This is a MUST WATCH for AR XA owners and enthusiasts, and anyone else who wants to be schooled on the most historically important and significant turntable design ever! I thought I knew a lot about these tables, having restored many and own two. Well I was wrong, and I learned a great deal from this professional, well researched, well demonstrated, and very informative video. Our host does a fantastic job of not only teaching us why EVERY turntable manufacturer either copied or borrowed from the AR XA design. He also demonstrates these significant design characteristics to "Hammer" his point home (sorry, couldn't help that one)! This is an extraordinay table and I would like to see how the Linn, Thorens, and other tables stand up to these same tests! If you love your turntable and listening to your precious vinyl as I do, then we all owe a debt to Edgar Villchur! Watch and learn from this great video.

Not only was he an innovator, he was practical.

Yes indeed, he got it. Turntables don't (or at least shouldn't) make ANY sound; it's the CARTRIDGE which makes the music! All the turntable/arm does is silently propel the medium along and hold the cartridge - in the exactly correct position and with the exact amount of tracking force, even on warps. - with the platter rotating at a very exact and unwavering speed, regardless of conditions (heavily modulated passages, for example, have more friction and can temporarily slow rotation on lesser brands) - rotating without any eccentricity (it should rotate in a perfect circle, not an ellipse) - without any vibration migrating to the platter/arm from the motor, platter bearing, nor room - without any motor EMI hum field being picked up by the coils in the cartridge (hence AR's use of a plinth with a steel top plate to block EMI/RFI from below) - without any audible warp wow (hence the use of a very low pivot point height)

I bought an AR-XB turntable back in 1975 when I was a teenager, simply because it was the cheapest "serious audiophile" turntable available at the time. I quickly fell in love with it! One day, a friend of mine bought a table, with all the bells and whistles, costing 10 times what I paid for the AR. I brought the AR over to his apartment for a side by side comparison. We did many of the tests shown in this video, including cranking up the volume to induce acoustic feedback, tapping on the plinths, jumping on the floor and of course just playing records.The AR put my friend's turntable to shame! He was so pissed! It was the only turntable I ever owned since the day I bought it, until it was lost (along with everything else I owned) in a tragic house fire. Besides priceless family photographs and memorabilia, the loss of the AR hurt more than anything else. One day I'll get another.

I have one of these in a box in my basement and it drives me crazy that I can't find it. There are many hundreds of unopened boxes in this house since I moved in 21 years ago. I bought it at a church bazaar for $2. It really was a landmark table. Fantastic performance, fantastic price. Just like everything else Villchur did. He's what I call and intuitive inventor. He was not a scientist or an engineer but he got right answers, was very enterprising, and sold his products at affordable prices. You're right, the AR-XA turntable was a landmark. Many others copied his spring suspended subchassis including my best turntable Empire 698. Like the 598 it has the same design in that respect. They also used the outer trim ring design which I think was originally copied from Thorens. But Empire has a massive 8 pound individually balanced platter on a huge journal bearing in individually machined pairs to +/- 1/100,000 inch giving it a claimed unweighted rumble of -90 db. What AR calls neutral balance Empire called dynamically balanced, that is the center of mass of the tonearm at the pivot point, the pivots in their case being sapphire bearings. In the Empire arms tracking force is applied with a long clock mainspring, not a weight imbalance. In an earlier embodiment of the concept without the suspension, 398GA a small weight is used for aniskating just like SME. In 698 it's set with a dial. The indicated applied tracking force markings on the adjustment are dead on correct according to my guage. Anyway Villchur had to build one hell of a turntable to prevent rumble and acoustic feedback from the likes of AR3. I actually met him and saw him perform the hammer demo at a hi fi show when I was a teenager. My best speaker system is Teledyne AR9. I've got a lot of other AR equipment.

I bought one in '73 and it was one of the best bang for the buck audio purchases I ever made. It was about $80 mail ordered from the now defunct Illinois Audio which was on of my favorite sources of high value hi-fi in my youth (I was about 13-year old then). Your video really reinforced my excellent experience with this table. I always thought the AR turntable was an excellent design all-around save the headshell perhaps...now I get the hidden beauty of the "box" plastic head shell. I don't know about you but once you've had a well-made turntable with a suspended sub-chassis you kind of have contempt for the plethora of modern tables that saw both low and high mass bases with vibration absorbing feet. You have also educated me on the beauty of the AR tonearm's pivot point. I find your way of both audio and electrical measuring of the isolation and tracking of the AR a real window of this simple machine's brilliance. I couldn't agree with you more when you state that the AR turntable is one of the most important turntable designs of all-time. And this point brings us a question. Why in the day and time where vinyl is experiencing a resurgence has the AR Turntable not been re-introduced? If you look a bit you can find some references on the net to the fact that around 2017 it was rumored to be coming back. It didn't happen however and I'm scratching my head. Perhaps the closest thing made today with at least a floating sub-chassis is the Linn LP-12 which is at a minimum north of $2.5K. There is a real need for a newly minted AR Turntable and your excellent video should be all the proof any rational soul needs to come to this conclusion. I don't count the Project Classic as such as I don't think it has a T-Bar sub-chassis and it certainly seems to only sorbothane puck under the top plates. I also imagine the tonearm isn't supported on a common under plate support with the platter (I"m not certain of this I admit). Please someone at AR either re-introduce this excellent front-end or license it. Thanks for your absolutely eye-opening real-world proof of just what an amazing piece of audio history this fine turntable really is. Fremer can keep all his mega-money ruminating for his elitist fanboys who must have butt-wiping money to burn. You have hit the soul of true audio brilliance here.

Good to hear. For the best possible sound/vibration isolation it may be necessary to replace the rubber grommets (washers) at the base of the three suspension springs. This rubber can harden and get stiff over the decades which compromises the performance. Amazingly my local hardware store had them in stock in their large "nuts and bolts" drawers section and people also sell kits for it on line. Apparently the designer had the forethought to use some existing, generic, easy to find spring/rubber shock mount. I show a close up of it at 28:47

@@m.zillch3841 thanks for the advice I’ll look out for those. I’ve now got it all set up with an AT VM 540 ML (about $300 ) tracking at 2g. I took a lot of care on aligning it with a very good protractor and invested in the fantastic iFi ZEN phono preamp which was about $200. This uses top quality components and is also built to last. Overall this is a great combination and my vinyl has never sounded so good. What amazes me is the perfect tracking especially on classical music where most inner grooves are very loud and brassy endings. For a simple looking arm this is outstanding. Now I just need a top quality amp to complement the system. Got a budget of between $1000 and $1500 and need typically 75 to 100w per channel into 8 ohms. I was considering the Cambridge Audio CXA 81 as it has won awards in the U.K. and has no compromises (no tone controls, no balance control, no phono stage) so it can exploit the iFi’s full talents.

Wow what a great video. This must be the most detailed and informational video on turntable design on the KZfaq website. I have been using AR turntables for over 45 years and have three of the XA models and one of the 1980s Resurrection models. I would note that the AR's are susceptible to footballs on a wooden floor. This is due to the resonance frequency of the suspension coinciding with the resonance frequency of the floor. Thank you.
@m.zillch38414 жыл бұрын
Thanks. The susceptibility to footfall often comes from placement on a shelf/rack with lateral motion/sway. The key to getting the best shock immunity on the XA is to understand that the three internal springs protect in ONE direction only: up and down. The springs provide very little protection from vibration that's side-to-side or front-to-back. [The hammer test I show at the end, for example, will completely fail if the XA is struck on a side panel instead of the top plinth.] People found it hard to believe but AR insisted that often the most solid location was to mount the XA directly on a hard floor (with no rug/carpet)! It has little lateral sway compared to a stereo rack.
@TomnJudy4 жыл бұрын
Dear Mr. Z, Thank you for your thoughtful reply to my comment. The AR"s springs have a natural resonance frequency of around 4-8 Hertz and will filter out vibrations above that frequency quite effectively However, vibrations that enter the plinth, (especially vertically) with a frequency at or below the spring's resonance frequency well excite the spring and can often cause the tonearm to jump from the groove. This has nothing to do with lateral movement from a wobbly rack. I have been using AR tables for over 45 years and they have always been much more susceptible to footballs than any non suspended table but this is a small price to pay because on the other hand they are much more effective at filtering out frequencies that are produced by the speakers, whereas the other tables do not. Nevertheless, I love your video and hope to see more from you in the future. kindest regards.

Wow-and-flutter, WnF, come from many sources and sometimes is embedded in the music in the grooves themselves (the cutting lathe's rotation as it cut the disc can be at fault, or the master analog tape deck may have had issues too), however the AR has the best shot of eliminating or at least reducing all the other problem areas, namely platter rotation, off-center or sloppy spindle hole location, and warp wow, as I explain in the video. As for exact speed, be sure to clean out the platter bearing hole and apply just a couple of drops of oil, ideally sewing machine oil or light machine oil. The thrust plate at the base of the shaft may need to be replaced, or if you are lucky, as I was, simply flipping it over gets you to a new, nice flat surface. Also, test the speed with a strobe disc. [Although I show the use of a cellphone's gyroscope sensor and the use of the RPM app in the video, I no longer trust this method because of the considerable weight of the cellphone being added to the platter. I fear it will add drag and skew results, at least on this turntable, which was specifically designed to have the weakest possible motor to get the job done, because weak motors have weak vibration. This minimizes motor rumble being picked up by the stylus.] It will never be perfect speed (33.33333. . . . rpm), however you can tweak it slightly by ever so slightly tilting the motor towards, or away from, the platter's rotational plane,with a thin shim, or conversely, adjusting the front and rear suspension springs slightly so the platter tilts either ever-so-slightly towards or away from the motor's rotational plane. This is described in the AR's service manual, which you can download for free after signing up to become a member at Vinyl Engine. You also can download a free strobe disc there, I believe. (I use the free app True Note as my strobe light.) By doing all this I was able to get incredibly precise speed on mine, in fact it slightly beats a $500K turntable I compared it with. Recheck the speed periodically because it can drift over months (not perceptibly, but the strobe disc is very revealing) and also be advised that if you are being really, really picky you may need to tweak it for unusually heavy LPs or if you add the weight of a record clamp [not really an important tweak on the AR, in my estimation, but YMMV]. Belts wear out after years so be sure yours is in good shape, the correct one, and AR recommends you talc it yearly. AR encouraged the use of strobe discs so consumers could see for themselves how accurate their AR turntable was, factory tested and guaranteed to meet or exceed NAB broadcast equipment Standards.

They used to show off this feat in their showrooms, at trade shows, and in this ad: www.audioholics.com/audio-technologies/turntable-history/ar_turntablehammer.jpg The AR turntable must be placed on a dead solid, immovable surface with absolutely no sway for it to work so most affordable stereo racks won't do. I used my kitchen's rock solid countertop. And the rubber grommets at the bases of the three internal suspension springs should be new, soft, and supple, not the undoubtedly-now-dried-out, stiff, half-century old stock ones they installed back in the 60/70's when the turntable was originally built. I was lucky and found new ones in the nuts and bolts department of my local hardware store but there are online sources too. Have fun!

If I jumped in my room it would skip horribly. Glad I hadn't got rid of the AR. You can literally rap your knuckles directly on top of on one of these ARs and no skip no sound no nothing.

It initially looks quite simple but that's rather deceptive, because its engineering and performance are top notch. They are fragile though and people often break the threads because they assume it is like most other bayonet style designs where rotating the outer fastening collar will "pull" the headshell inward, towards the tonearm. Instead that action can break the delicate threads! Proper use is explained in the owner's manual: Insert fully and ONLY THEN tighten the outer collar to secure it in place! Doing so properly and they can last over half a century, like mine. AR warrantied them for initially 1, then 3, and finally 5 years, as well as the rest of the 'table, and replacements for the headshell after that were a mere $2, including shipping.

Kudos on the great job in interjecting easily understood scientific methods on a too often subjectively quantified subject. Now it makes so much sense. I had recently re found my teen years fascination with HiFi and finally put together a high end system that I sweated over back in the 70's. While I completed the system using all the top of the line models for the specific brand, I was always intrigued why the TT I bought was only considered Mid Fi, and most of my audiophile friends and community in general always gravitated towards the AR XA/XB, Linn LP12, and Thorens TD124, with the later two a copy of the AR floating platter design. Whenever I asked what makes them so different, all I got was subjective statements of sound quality, dynamics, and other reasons that I couldn't pin down. Looking at the AR, it reminded me of the Heathkits I built in the day and couldn't understand what all the fuss was about. So I bought a clean XB just to see and hear. I don't have an educated ear as some audiophiles have or claim to have, but it did sound good. But now with your video it makes it clear on what I should be listening for and what the differences may be. Thank you for that and clearing up the murkiness for me. I am sure there is so much more to be learned, but great video.

The Delphi or Rega cannot. Bump the tracking force up to 2.3 or thereabouts in those two TTs to achieve the same tracking ability of the same cartridge in that allegedly "poor quality" AR tone arm. ;) I've owned several expensive TTs over many years and none of them could (can) actually out-perform an AR XA as far as JUST playing a record and "staying out of the way."

It s clear that this is the unique reference on the cutting edge technology of this turntable at its time that was presented and made. Implemented in state f the art simplicity, functionality and extreme efficiency f the technologies applied in it. It is not only the the information that you are aware of it is also he way that you master this turntable in adjusting it in its optimum state! What surprised me is the floating chassis suspension and the wa it isolates exterior vibration. I'm an owner of two Thorens TD160 which have floating chassis as well but implemented in a slightly different way with identical springs suspension system. What is highly interesting is the efficiency of thensuspension. It would be very helpful if you share some of your knowledge in how someone optimises the suspension to perform the best way. We thank you for sharing all these knowledge with us! Friendly Greetng Panos

Thanks. On the AR the springs are adjustable once you scrape off some factory glue used to lock the bolts in place. You can then adjust the tightness of the 3 springs, known as "tuning". Depending on the record's weight [think those audiophile "200 gram" pressings, for example], plus the cartridge, mat, and any record clamp you may be using, you want to tighten them so the platter is flat/level and has about 1/8 to 1/4 of an inch (IIRC) clearance above the base plate. Check the manual. If all goes well the resonance of the entire floating section when pressed down and released should be around 3.5 to 4 Hz. Not sure if this is also true of the Thorens but I know they are similar.

Great educational video about the turntable I owned and used from 1969 well into this century -- too bad it explains an obsolete technology that at this point in history amounts to a pricey nostalgia craze. BTW, as delivered the XA had felt feet which tend to compress flat under the weight of the turntable and fall off after a few years as the adhesive dries out -- I replaced them with aftermarket tape recorder pressure pads when that happened to mine. Another weak point of the design is the cheap, off-the-shelf clock motor -- such motors have accurate rotational speed but are not designed to operate under the tension of a drive belt, so their front bearings will wear out much faster than a purpose-built counterpart and need to be replaced at an interval determined by the number of hours they spin under that tension. Thank you for an excellent presentation!

Very nice presentation. But to set the record straight, the 1955 H.H. Scott 710-A pioneered the 3 point floating sub-chassis (platter/tonearm combo) but it had a conical gear drive. The real pioneer of the 3 point suspension with belt drive was in 1958 with the Stromberg Carlson Perfectempo. AR, Thorens and others then followed suit.
@m.zillch38413 жыл бұрын
Villchur cites the Stromberg Carlson (and Scott? Weathers? I forget.) in his Audio paper but as I understand it the AR was the first to make a careful analysis as to where to place the three springs so that they would be equidistant to the floating sub-chassis' center of gravity. This improves stability greatly and when jostled it comes to a rest more quickly whereas some of the imbalanced designs wobble about for much longer when agitated. I also know some floating designs stupidly use four springs, not three, so they lose the "inverted, self-leveling camera tripod supported from the ceiling" effect. Not sure but I think some SOTA work that way.

For restoration I followed the advice from Vinyl Nirvana kzfaq.info/get/bejne/sK94nLCjppORpqs.html m/Turntable1.html I also joined the forum dedicated to it, vinyl engine, to ask picky details that came up and used John Weather's page on the AR-XA: www.johnsweather.com/Turntable.html I flipped the thrust bearing plates (small hard plastic discs) over at the base of the platter and tonearm shafts because they seemed slightly pitted. The new belt, ~$10 on Amazon, was nothing special, so not as good as what AR supplied which was machined dead flat on both sides on a rotating drum, once frozen solid with liquid nitrogen (I think), in order to minimize flutter. My current mat is Hudson HiFi Silicone Rubber I bought at Amazon. The rubber grommets at the base of the suspension springs were found at my local Ace hardware store. The AR manual and service manual, found on line, discuss platter leveling (spring tensioning). Other than defeating the arm drop damping mechanism discussed in the manuals and on one of Weather's pages, (you simply remove a pin), because I couldn't find a replacement washer and silicone, my unit is 100% stock. My cartridge is a Shure M97xE but they are discontinued and the remaining ones are pricey. Some other restoration details here: kzfaq.info/get/bejne/fch-qaZ8qMfNhoE.html

Unfortunately AR belts are no longer in production. They were specially manufactured by freezing them on a rotating drum (with liquid nitrogen?) and then they were precisely machined (ground to a dead flat, uniform thickness). This was said to minimize platter rotation speed fluctuations, aka "wow and flutter". I just bought one on Amazon which specifically mentioned it was the correct size and tightness for the ARs and it seems OK. . . . Another thing to consider upgrading are the three rubber "washers" at the base of the suspension springs. Sorry, I haven't been able to find/locate a good, low cost source for them to recommend, but they are sold as part of a complete "spring kit" you can buy on line. I amazingly found some ala carte at my local ACE hardware store in their "nuts and bolts" drawers in their "various cone springs" drawer, but when I returned a year later they no longer had them. 😕

Very revealing test this is. For the most part, but not everything, I’m pretty convinced. However, the absense of anti skate is a serious problem. I have been around long enough that even the lightest of the light tracking carts need anti skate. Tests that I carried out myself using all kinds of test records and ultra light tracking carts prooved that over and over again. The distortion that occurs without anti skate may not always (but often it will be) be audible, they surely are measurable. Also, the wear and tear of the side of the stylus towards the spindle will be higher. I have carried out my tests with all kinds of tone arms available back in the days. And the cart that I used were ADC XLM’s. By today’s standards a real pain for many tone arms. In fact, the mass of todays’ tone arms means they can’t accommodate the ADC XLM. I still own a new in the box XLM by the way. Kind regards from Hekelingen, Holland. Bye, Willem.

The photographs of the oscilloscope in the linked to Audio article prove that with the ultra low mass of the AR-XA' turntable's arm/headshell [the lowest of any ever made at the time] and the proper tracking force distortion is not a problem without the use of anti skate. This doesn't mean this is true of other turntables however. If it were true that the lack of anti-skate prematurely wears down one side of the stylus in a significant manner then how do you explain that there's not a single photograph of such a worn stylus in the entire history of modern, stereo LP use? The XA was a popular design in production for over a decade so there are many (hundreds of thousands) of them out there "wearing the stylus unevenly", plus other designs from VPI and others similarly don't have anti-skate, yet we have no photographic examples of this supposed, uneven wear. [Psst: diamonds are extremely hard. Rubbing one side of it with the pressure of a feather, even if for a thousand hours, doesn't do much to it.]

A very thorough review and interesting tests. After AR had announced their XA turntable but months before they released it I put in an order at my local hi-fi shop. When it did finally arrive the serial number was 00047. I paid $78. I agree with you that it was indeed ground-breaking. The tonearm did have a couple of weak spots, however, that you fail to mention. The teeth of the coupler of the headshell to the arm were of the same plastic as the shell itself and tended to suffer wear over time I never understood why AR didn't make that coupler from metal, which would have avoided a big problem. Also, the headshell coupling design could have been made standard so that other headshells could have been fitted to the arm. As it was, no other shells could be fitted, and as the years went by, it became more and more difficult to find an original headshell for the table. By the way, you don't mention the snazzy little kit that AR supplied for adjusting the tracking weight. That hammer pounding on the table was one of the ads that AR used to market their product. Never tried it myself.
@m.zillch38414 жыл бұрын
Thanks. The hammer test only works on a solid surface, like my kitchen countertop I used. Attempting it on a rack doesn't always work well and of course the internal springs provide protection ONLY from vertical shock (and room rumble) but do little for lateral shock, nor front to back shock. In order to put out the lowest mass tonearm ever released on a TT, AR abandoned their metal headshell design and converted to acrylic at the last moment before release. You are right that the "teeth" of the threads are easily broken but in AR's defense they show in the instructions that the headshell should be fully inserted with one hand FIRST and then held in, pressing against the spring, while the other hand simultaneously tightens the outer collar to lock it in place, hand tight only. Any attempt to suck the headshell into position via the screw threads, like one can on a Technics TT, can snap the delicate, low mass acrylic teeth. New headshells were a bargain, by the way, at only $2 each with free shipping back then!

One can never 100% eliminate inner groove distortion on ANY turntable/arm even by moving to a linear tracking arm. Geometrically the LP's inner circles are smaller, tighter, and have more curvature so they "pinch" the stylus, also providing less info per angular rotation (but the cutting lathe attempts to jam it into the tighter linear space anyways). Setting the overhang properly (via a small screw hidden underneath the back of the arm in this design) and using a good protractor during stylus setup is all an owner can do, but they can't change the format itself.

I'd also like to see if you can determine the best turntable platter, whether it's felt, cork, vinyl etc. and don't forget the argument about interconnects and speaker cable! Cheers for the information....now where can I get my hands on one of these turntables!!

Very very impressive turntable, I have 2 very good turntables but if I ever find one of these for sale I am getting it. BTW the hammer and nail demo would have been unbelievable if not on video... can't believe you actually did it but thanks so we don't have to. This is the Volvo P1800 equivalent.

AR showed off the XA turntable's incredible acoustic feedback immunity and shock/vibration isolation using a hammer blow both in their showrooms (one of which was right in the main concourse of Grand Central Terminal in NYC) as well as their magazine ads: www.vinylnirvana.com/history/ar_brochure_1.jpg Of course consumer video distribution didn't exist back then so I thought to prove it was legit on KZfaq.

This is the best techincal analysis of an audio component I have ever seen. That said, I have to disagree with the AR XA's designer on one point. Edgar Villchur said that he disagreed that the turntable is the most important link in the audio chain. You have demonstrated here that the turntable has to do so much, from isolating the playback system to maintaining constant speed to tracking warps to even centering the record and more, nothing further down the audio chain can correct the signal if any of these processes is poorly executed. He's still a genius.

Thanks. Well I think Villchur's point, "The turntable should stay out of the picture" means that if your turntable contributes to the sound in any discernible way, other than being completely transparent and invisible to your experience, then what you have is a BAD turntable. Listening to a good TT is like looking at a pretty view outside a glass window: ideally it should be so incredibly clear (transparent) that you can't even tell it is there! Good turntables are dead silent and don't make any sound; It's the cartridge that reads the grooves and the TT (and tonearm's) only job is to let it do that as best it can, without adding anything to what the cartridge does.

@@m.zillch3841 I understand his point, but the turntable staying out of the picture is not a passive process. As you showed in this video, the turntable has to do many things actively. If there is no isolation from feedback, the stylus to groove circuit is not tight mechanically, the speed isn't constant, the motor and bearing generate noise, and the tonearm can't keep the stylus in the groove, the best cartridge in the world will misread the musical information. Going to your analogy of the turntable being like a transparent window, windows don't stay clean all by themselves. Someone has to put a lot of elbow grease to keep it clear. The analogy I would use is that it is the walls and roof of your house that keep you dry, but without a solid foundation they don't mean much. I see the turntable as that foundation.

@@johnnybgoode1950 I additionally think what he was largely objecting to is high end reviewers describing turntables as having "a sound signature". They don't; at least not good ones. Going back to the glass window analogy, if it is described as giving the view a "particularly appealing tint", then what you have on your hands is a BAD window. The window should be so clear you think somebody forgot to close it! No tint. The job of the window is to faithfully render the image without any alteration whatsoever. Turntables don't have "good dynamics", "imaging", "tonal balance/frequency response", "stereo separation", etc. as the reviewers he objects to often claim .Those are aspects of the cartridge (perhaps), the particular recording, and the peripheral playback chain including the room acoustics and speaker placement. He also never said "Staying out of the picture is easy and everyone's TT does it", but perhaps he didn't appreciate that his design did it successfully for a fraction of the price than other ones which also "stayed out of the picture".

@@m.zillch3841 I can appreciate that he was objecting to those reviewers who were worshiping the turntable, but those reviewers at that time were experiencing a seismic change in thinking. Everyone thought that the speakers were everything and all the turntable did was go round. Linn did not give the AR it's due credit, but it did demonstrate that turntables made a big difference. Like many ideas that change suddenly and very unexpectedly, it got carried to fanatical extremes and Linn rode that wave all the way to the bank. Most of what they did was just to improve the tolerances to which the AR was being built. I think the difference in the way I see the issue is that the turntable must do many things actively to appear completely passive. When I set up a stereo system or a PA system I emphasize the source components more. It makes more sense to start with a good signal than try to fix it down the line.

@@m.zillch3841 your video is what convinced me to pick one of these up. It's been a year of great listening! I love the simplicity of this turntable and the modding culture around it is interesting. The shop I bought it from drilled into the headshell so they could mount an ortofon blue cartridge hahah maybe that is less than ideal but sounds great to me cheers!

@@khemshet Good to hear. Drilling the top of the headshell is indeed a common mod and maintains everything that's good about the headshell yet improves the selection of possible cartridges one can use.👍
