what are your thoughts about digitizing vinyl such as Technics does with the SU-R1000
@terrywho229 күн бұрын
Very nice discussion of the differences between engineering audio playback and the art of audio playback. The former focuses on the accurate reproduction of music, attempting to extracting every detail as correctly as possible. The latter is primarily concerned with conveying the message and emotion of the artist to the listener as fully and completely as possible. I agree that that these can be different things. Interestingly, one could argue that in the case of the art of audio reproduction, some of the burden is on the listener.

I have not heard the Encores. However, the Encores are small bookshelf speakers, and they match very very different systems than my speakers do. Performance-wise: I think that's a moot subject. The question is always which is the one you like more... Knowing my preferences, for me anything that's less than 91dB/Wm is unacceptable - unable to resolve low level details, dynamic contrasts, and presents a dead / uninvolving midrange. Can still produce a wide frequency band, play loud, but without the rest it's not my cup of tea.

When I let people listen to one of my single stearo towers. They have to lay down on the floor , or take a walk. Or they go into twilight zone mode , and go into musical shock. Everything they thought they knew about sound reproduction goes out the window. Two speakers are not only unnecessary for perfect stereo reproduction. But are actually detrimental to the reproduction of music program. Due to unstructured wave overlap. This technology is as different as tubes and fets. But is better than both. Because sound propagation is treated as a science. Where act wave manipulation is employed. 😊

Hi Janos, as someone only using digital sources and also did some massive test on DACs and Streamers, I'd never ever go back to Vinyl and I"ve hifi buddies with some extreme Vinyl setups 😊 Unfortunately the DAC chase is a BIG BIG KZfaq topic and you see on a daily Basis new Review. My experience is that the best I'd tested and now own are in one extreme FPGA-based (Grimm Audio MU2, very sophisticaed DAC chip and output stage) and in the other extrem full-vintage from Abbas Audio (TDA1541A and PCM63, he is using even using only old copper from vinatege devices ). YES, I only listen to Qobuz/Roon or DSD files (nativedsd downloads) and of course very special recordings on CD, because some CD records outperform certain HiRes which is just upsampled. So recording must be carefully selected, like with Viinyl 😉 I've to say, even I own very expensive DACs and Streamers many times 44.1kHz/16bit sounds better as many HiRes or DSD titles. I do highly highly recommend to listen to CDs/Vinyl from THE LOST R3CORDINGS (france), I own all of their CDs and this is 100% timetravel, those recordings are just a different league and mostly concerts which have been Lost for centuries! Best rgds from Germany!

Very good points Janos! Thank you. You understand the magic music works on our souls. When we train ourselves to be critics, of the sound quality or anything else, we are deliberately stepping back from engaging and being immersed in the transformational experience. If you approach your meal with the mindset and vocabulary of a food critic, you might well enjoy the visceral experience far less. And possibly gain less nutrition as a result!? The problem with digital is that it has a finite sample rate and resolution. When the CD standard was established, the electronics were crude and storage was limited. Brick wall filters were used and dynamic compression. A very dynamic track (like most orchestral music) requires reserving headroom for the loud passages. This means quite passages are running on much less than 16bits.

I don't understand anything.😂❤🤔 Maybe I have no feelings or no way to connect to them..😂 I have thousands of LPs. And I have optimized my room and system with my turntable and those LPs..😂 "optimized for analog.." I am logical and thinking audiophile terms all times. All the technical types of LP recordings. All from recordings starting from 1906 and forward. Tying "direct to disc" recordings, Direct to Metal, first pressings, modern pressings of old recordings, mono/stereo, special audiophile pressings and so on and on. After optimizing and modifying front end TT and everything else. What I can say with a certain is that reel to reel (R2R) of a old (analog) recording is SUPERIOR to any version of LPs issued of the same recording! The problem is that most of us think that R2R is so much better and LP is the next best sounding that we can lay our hands on..😅😅 That is true but nobody reflect over.. HOW MUCH MUSIC IS PROVED TO BE LOST WHEN MAKING A LP, AND PLUS ALL ADDED SHIT THAT WERE NOT PRESENT IN THE REXORDING SESSION OR IN THE R2R THAT WE GET FOR FREE!🎉🎉 The ting is when I have optimized my system with TT, RIAA and DSP. That LP LOFI that NEED ALL help it can get (that is why we make tonearms using silver wires, advanced stylus shapes, on the fly SRA adjustments and so on and on (the list goes on)...😢😂 So my system is optimized with all of those LPs and when I switch over to digital playback. Then wow!! 🎉🎉 All those optimizing (except the frontend of course) will also benefit the digital playback!! So what we can say that by optimizing with LP (LOFI) then you need tweak everything everywhere when the source is so poor that it needs every help it can get in any form it can get.❤❤ Yeah, I have not the latest and I am a DIY with 40 year old magnapans that are highly regarded so no wooden box either so no emulation of acoustic instruments or other brain ghosts to chase.😅😅 So my personal conclusion is coming from that everyone says that LP is wonderful, analog is the preferred version, this and that old recording is just wonderful and so on.. (How do you think that I got all of those old recordings.. Yes I listen to "experts" that says this is great because of this and that.. Yes, I am courios to learn what they hear and I just source that old pressing..😂😂 but it is not even my preferred genre..😂😂😂 but shows how far I am going to find out what is good..😅 I am so easy to influence and I have during many years collected, studied, tweaked and DIY optimized. 😅😅 So I know at least two or three ways to adjust every angle on the stylus plus which one is the most optimized using and trying digital microscope and other techniques.😮😮 When nothing is left to the chance I can easily say now after intensive many decades of modifications, optimization and tweaking.😢😢 That no LP is not the magic bullet😢😂🎉 And MY mistake to listen to those that says it is so "wonderful".😂😂 (Not that someone else is doing the same wasteful journey, if the goal is the "nirvana of sound quality"..) It is fun hobby anyway.❤😂

@@EduardBroekman Thanks, that is a interesting rabbit hole to go into with mono.🥳 Unfortunately that has not been explored by me of several reasons. I have one TT with one arm board. And no quick connection for the head shell. Making a "quick" swap not that "pain free". So all my modifications and adjustments efforts went into one TT and stereo cartridge(s). Not having enough mono LPs to justify the work and cost to swap and buy a true mono cartridge. 😥 I have one of many projects/ideas regarding mono/stereo comparison. 💖 When I got a set of LPs of Miles Davis that contain a stereo pressing and a mono pressing of the whole album on two separate discs in the same album. My idea is to compare them when they probably is cut from the same source and produced on the same vinyl compound in the pressing plant (yes the cut and plating is producing other metal parts and they will differ). 🤔 Probably the closest comparison between mono vs stereo I could be able to do. 🤔 But I have not yet played that specific mono LP when I got several other stereo pressings of that album (Japanese, UHQR and so on). 🥰 And I know that to give the mono pressing a fair chance I need in my mind use a mono cartridge and do the comparison "correctly" and fair.🥰 And of course I have listening on other mono LPs in my collection but with my stereo cartridge. 🤪 And I hear the "potential" and how great they actually sounds and it is somehow in its "simplicity" captivated. 🤓 And sounds much better than I could imaging, feels like and sounds like, that less is more somehow.🥰 Do you feel that you can connect to the music better with mono than stereo ? I guess the power of mono is that there is not that much of the added information of stereo information that clearly makes it interesting with sound being placed horizontally and the ability for sound being panned left to right as a effect for example. 🤪 I suspect that all of those "stereo effects" makes it interesting/fun/spectacular. 🤔 But on the other hand it is probably in reality is a distraction from the real core/emotions of the music and makes it harder to connect to it!? 🤔🤯 For example do we really need a sound/instrument that gets panned left to right back and forth..🤔 Yes it is a cool and interesting effect that entertain and draw our focus towards that effect as wow and cool it sounds.. But is it music or just a ADDED effect to the music?! 🤔 When it is not coming from the artists really in many cases and it is a added artistically effect in the production after the recording have been captured by a mixing engineer. That draw a knob (or in the computer) left to right or just place the captured musician (from his microphone) to the left of the singer when it could in some cases be 50/50 percent chance that he could placed him to the right that day! (Especially on recordings where the musicians were recorded separately and were not at all playing together in the same session.). I suspect that it steel and robs our attention to the music and MAY be one reason why I maybe don't connect to the music in a deeper way ??🥳💖 With all of those "distractions" that is in its core not music from a artist..🤕🤯 What is your experience and thought, regarding this as a dedicated mono consumer ? 🤔

Sorry, to clarify the term LP as "LOFI".. It is not the same as saying it is not good enough.. But that is a whole other discussion.. 😝 I got it from my daughters husband friend. 🤕 When he is younger (40 year) and I were showing him my dedicated listening space with the system.. He referred and pointed to all of the LPs as "LOFI"..🤣🤪 We did not have time to listening to the system at that point.. 🎶 I were reflecting on the given "LOFI" remark. What did he think that someone put all the effort with treating the dedicated symmetrical room without comprises, and then just put on a crappy LP with bad sound to enjoy all the spent time and efforts?? 🤯 But yes the man have defiantly a big valid point.. 🥰 (I am not trying to stroke my brain to convince my self that that LPs is something better than they actually are.. They at what they are..) 🤓🥰 But I guessed that the man had some skewed view of what level of sound quality LP can in practice give. 🤔🥳 So the next time he were on a visit I had qued up a song on Michel Jackson thriller album (ultradisc one-step pressing by mofi. (Yes, just that ONE that started the mofi gate scandal. That showcased that audiophiles can't hear a difference between a digital processed LP or a fully analog one!)). 🤣🤣 And also stated the same tune on streaming. 🍭 All level matched. 🎶 Placed him on the sweet spot with the remote.. 🎂🍻 And told him: Here is the selector for switching between the sources. You don't see or know what source you got. The same song is playing. And you just need to identify which is the "LOFI LP" and which is the "superior" HIFI streaming? 🤣🤣🤯 Well it were one of the better LPs that I used so no klicks or pops were present on it so it will not give away that it were the LP source.. 🤪🥰 But anyway the random man with his preconditioned mind set of LOFI. 🤪 I saw him struggling and almost sweat when he were not able to determine which source were what with the remote in his hand going back and fourth.. 🤣🥰 And maybe he got a different view point and respect of the LP LOFI and its sonically capabilities. 🤔 Mission completed! 🤣🤣🥳 Note, that even with one of the BEST or BETTER LP pressings and tweaked front end TT (micro line, silver tone arm cables, discrete RIAA and so on).. The LP did NOT blow the streaming out of the water or were superior in any way. 🎶 Even when the streaming setup is a modest setup and far from tweaked and not put all of the work, attention and efforts into it as the LP frontend needed and had got. So the average LP in a collection has a lower sonic qualities than the one I used for this comparison. 🤓 (Limited pressing and retails for 100 USD for a record..) So with all that in consideration LP is LOFI but can be good or "good enough" and there is other reasons to listening to LP than just sound quality. 🥳 And we should not mix those two things together that LP is the same as "good" sound quality automatically! 🤯🥰

@@AmazonasBiotop There's a lot to unpack and in your thoughtful comments, but in short I'd say this: if you discover, or you prefer above else to feel directly 'why is an artist on stage', anything beyond mono is a distraction and actually anything that tries to impress/stand-out. Music is of the whole, the invisible spirit that interconnects every part, has it flow, expand, contract and perform magic. Mono also sounds far more like what you'll hear live with your eyes closed. For me mono also helps in how I listen to music: anywhere in the house, not sitting down in a sweet spot: the whole room is the sweet spot here. This is partly because I employ a nearly complete omni directional mono speaker, so I enjoy a near-total lack of phase cancellation and a very even sound level throughout the room. It also sounds great in the next room. On the pragmatic side, it allows me to far quicker prototyping of cables, amps, .. at half the cost - or doubling the budget for the same component! Now finally, to return to the subject of this video, it's my experience so far that a mono system is easier to tune and build to get in touch with the heart, soul, energy, flow, inspiration that created the recorded music... it also forces you to get fulfilment from music that has less distractions, so it comes from both ends. The way I started my journey was just listen to one channel, reposition your speaker where it sounds the best and then live it for two weeks - it will take that kind of time to getting used to it.. Don't expect though that you immediately will 'connect', there's no magic bullet for that but at least you've got a nice TT setup, so you've got elements in place that make it possible. I also bought some records that others had heard once that so impressed them (on let's say a exotic horn system at a show), but that same album sounded so shite at home so that got them into a journey to get the same sound... and with me having such records, it does the same.. at some point as the system gets to a point where these 'difficult' records comes to live, and so they help guide you to where the barriers between music and you are disappearing. In my experience, you'd like your audio system to get out of the way of music ... for which it doesn't need to be neutral but can pass on the spirit and energy when they hit 'record' !! :) Hope that makes some sense :))) Btw Janos has excellent record tips for this.

But I am lucky to also being able to work in the sweet spot but as said stereo is still a distraction in that position. 🤔 Maybe I should pursue more mono listening in my life..🤯👍🥰 Question have you a technique or a preferred way to make music of today into mono ?? I mean when they pan stuff and put stuff to the right and left on today's recordings then just taking one of the channels will make you to loose some information that is only present in worst case on the other channel. 🎶 So I guess it needs to be summed together, L and R somehow.🤔 I am not interested in to just listening to only 70 year old recordings that were recorded pre introduction of stereo. Then we miss out of 90% of today's different genres..🤔 Maybe it is OK to just take L and R RCA and sum them into a Y connector and get one summed channel? Or is there better ways to do it? 🤔 Did a quick google search and found: "To sum a stereo pair to a mono signal it is recommended to terminate 2 1K ohm resistors to the Left and Right channels and then tie them together. Solder one side of the first resistor to the left channel followed by soldering one side of the second resistor to the right channel." 🤔 Funny that we came to the same conclusion but from different experiences. 🥳🥰

Great video! What I like about those early non-microphone recording, is that our stylus wiggles in the same way, the original stylus carved it into the shellac master... nothing beats such connection despite it's limitations.. the sense of 'registration' or being allow to pop into that performance is something that 'technology' can't provide as I feel it inserts to many steps between event and us to listen to it again. In some sense, what pro-digital people say is to get great music, let's digitalise it, then analogue it again... looks like saying to get the best steak, we must mince it first and then re-create the steak... that make so much sense ;-)

So well said Eduard! Since then we have all the hype and show, but the direct link provided by shellac-stylus is gone. If I engage my clinical brain I can dissect the sound and figure things out that lack in technicality. However, the mind refuses to go the clinical way, it's a direct heart-to heart connection that is entirely unknown in later eras. Yes, each technology has its own aspect, and we are so easily dismissing the lack of the most fundamental aspect because we don't get to experience it.... and it is this lack that feeds the never ending hunger to up the technology, and in the meanwhile the answer lays in simplicity, to go back to the foundations, the roots. I was super busy lately, did not get around anything audio. I've read your email about the 3-way extension with the midrange unit. My take is that I cannot predict which version will give the best tone. You could optimize it for linear output, but tone takes priority over that, and it's next to impossible to predict how the crossover regions interact with each other. You will find the optimal solution by playing around with the values once it's up and running. Also, the exact positioning of the low midrange cabinet will affect it a lot, will give plenty of room to play around.

Hi Janos, thanks for the subject. You present this as an option for the beginner. But the approach also works for the veteran, based on what he wants of-course. I guess it goes without saying that if you want to do this, it is worth while watching some GR Audio videos. Danny has made this his business and he seems to be good at it. He also has a fetish for flat frequency curves. If this is your first battle, I would not bother with that and I would stick with the original component values (If that is the better approach in general, is a different matter for discussion). Many cross over coils do not have the inductance value written on it, so you may have to invest in a cheap LCR meter. e.Bay is your friend here. If you are on a budget and you like your cables, hard wire them in the cross over and save some money on the tube connectors. Even though the speaker you are going to upgrade is probably not a life design (Janos has many videos on this subject) be careful with bracing a commercial dead speaker, specially if you like the tonality and dynamics of it. A dead speaker can actually be seen as a narrow band life speaker. And many *good* speakers have those resonances at frequencies (by design or coincidence) that are as little obnoxious as they can be. If you start bracing the cabinet you will make it stiffer, but it is not a given that it will sound better. If it is booming, then go for it :)

Before anyone invests serious money in upgrading speaker, I'd consider the bigger picture. My best two choices in hifi recently have been moving to high efficiency drivers and adding an analogue source which allowed me to listen to recordings with little to no post-processing, which greatly helps any tweaking. Now, to go back to best thing no1, high dynamic efficiency drivers have their built-in benefits such as way less compression, more nuance/detail, less distortion, sounding good at low levels... but they also minimise compromises for power in the amplifier which I now see as the most influential in an audio system in matching the source to the speakers. So yes once one has their system worked out this optimising is awesome and totally appropriate but if you're working with low efficiency dynamic drivers, to me that appears somewhat like carefully arranging deck chairs on the titanic... Ok one last thing and nit-picking on one comment you made in this video, but the advising a Voigt pipe with a (high quality) 90dB/W driver seems to be a choice for a very particular type of listening.. you have the experience Janos but I see a very small sweet spot, needs a particular sized room, the aesthetics commission can allow proper placement of the voigt pipe... and depending on the room size and listening levels, it's likely to need power-derived quality compromises on the amplifier for it.

Hi Eduard, I can totally see where you are coming from. But there are many reasons why somebody wants to do this. The most important one in my opinion is for people who have treated their Hi-Fi components as black boxes so far. It is a very important gate way in getting confidence with DIY Hi-Fi. Some other people may have confidence but cabinet building is not something they are geared up to. Or they are stuck with certain types of gear for esthetic reasons, for good or for bad, that is not up to us to prioritize. Any way, I agree with you that if sound is the end goal, the combination of high efficient speakers with low powered valve amplifiers is something you ignore at your own detriment.

In order to get the equivalent speaker to an upgraded crossover medium price speaker you need to spend over $20K. I have upgraded several and the results were amazing. Just replacing cheap posts with tube connectors, $30,, makes a significant improvement.

Thanks for this advice! I found a nice pair of Mark Audio drivers for my first Voigt project. The CHR-120 with low resonant frequency and exceptional Xmax. The shallow cone and adsense of a whizzer cone should make the dispersion pattern more even... Methinks!?

Older jazz recordings, where some instruments are separated (completely or partially) on the left or right channel, by changing the channel inputs to the amplifier, revealed significant differences between FVP (folded Voigt pipe) and VP. The FVPs appear to be slightly livelier, but also less balanced, with more problems with certain tones and harmonies and more audible driver distortions at the same loads. Also, the FVP cabinet shows more resonances. This is especially present in the upper area of the cabinet, around the driver. It's true that some resonances are pleasant, but unfortunately they also stick out tonally too much. Changes in damping have a smaller impact than desired. Additional reinforcement - thickening of the sides silences these resonances, but then the sound is just not right, and the problem of driver distortion when under load cannot be solved. there are fewer problems with VP, or they are virtually non-existent. Based on the above, I concluded that the very placement of the drivers in the upper closed part of the cabinet causes these problems due to too much released energy, which the cabinet is unable to release due to the very shape and position of the driver, which results in problems. Therefore, I very much agree with what was stated in this article - video, that VPs are probably the only ones that ensure the operation of the speaker without (or far less) certain problems, which are characteristic especially of bass reflex and closed designs. Therefore, drivers of classic softer materials and more natural sound (paper bases) will generally have problems with certain loads in such designs. That is why the tendency of driver manufacturers is to use ever harder diaphragm materials, which does not mean that the problems are solved in the classic box. I also think that this is a logical problem for full-range drivers, which are already quite loaded and additional feedback energy - the load from the cabinet significantly affects the quality of the presentation. I don't know much about horn speakers, I have no experience with building them, but for now, after several months of experiments, it will probably hold that VP are the most optimal and simplest design for maximum efficiency and minimum distortions and overall problems.

Do you think there is any merit making an analogy between sound and a random-dot stereogram (a 2D-image composed of random dots that when viewed correctly will mentally produce a 3D-image)? I was thinking that sound:music :: RDS:3D-image. As is the case with RDSs, a fragile mental state can be obtained where the 3D-image is perceived. Similarly, music can be perceived in a fragile mental state when listening to sound. Extending the analogy further, as adding color to a RSD can ease the perception of 3D, perhaps tonality aids in perceiving music from sound.

Obbligato (for tweeter), mundorf and jantzen cap are inside and they sound great on a luxman r115 receiver.

Thanks for another interesting discussion, Janos and Kintaro. Since heat is related to the Brownian motion of molecules does it follow that damping materials are actually changing the frequency of the left over signal? Thanks, my friend!

Very interesting take, Janos! My short experience seems to go along this as well. I am finally having a blast again listening to vinyl with my newly added Trumpet MM that has only few hours on it! It together with the(not so old) tube amp are together giving a "life" to vinyl that I never heard before in my system 😊

I try to use resonance , not cancel it. I have developed an epoxy based speaker box coating. Thin textured layers, premote ( refractive resonance ). Flat surfaces are not conducive to resonance. Precisely, for the thermal characteristics mentioned here in. A micro splaying effect , that uses resonance , not fights it. To refract resonance into usable energy. Why waste it ? Resonance is like a turbo charger. Energy out the tailpipe ? Or recycled back into the engine ? The ancients used resonance and reverberation in ways we have yet to re-learn. Stone pillers in India. Appear all the same size/density. Yet all reverberate different musical notes on the scale. Resonance 🤔.

Dampening .............your obsdervations are correct . Another issue with damping is that' dampening is NOT uniform to variable sound pessure levels ( music equals dynamics) and damping is not uniform troughout the frequency range...... Also in a town the noise floor is HIGH but composed by countless noise sources, vehicules , human activity a quite nd reflections between buildings...etc , you get used to it and it becomes the reference .....but in a rural environment that is rather very the silent disturbed by the the passing of a single little motorcycle is an almost painfull experience. Have a sunny day Janos.

Hi Janos, this is a great video because it makes us think (well, at least me) about the topic at hand. I would like to weigh in on something I heard you saying a few times now. That is that modern speakers and modern amplifiers are not made for turntables. And I agree with that, so far as that it is unlikely you will get most out of your turntable with modern equipment hooked up to it. What I don't think is that modern equipment has been designed for modern DACs at the expense of turntables. I think a vintage ladder DAC, like a TDA-1541 will also sound better on tube equipment with a full range driver. Though a modern delta sigma DAC may be disappointing on this equipment. But what is going on is that on one hand there is a trend to make smaller speakers, enabled by the ease to build high powered amplifiers. And on the other hand sigma delta DACs became the de-facto industry standard, because ladder DACs are more expensive to make and a pain in the a$$ from a process perspective. With these developments it became more problematic to make music sound musical, thus progress (for the sake of progress) was made to make it sound "High End". Then it was only a matter of gas-lighting the end user and re-writing history (as to what it used to sound like) to the point that the way music used to sound has become a niche. Any way, that is my take on it :)
