Bob Pease had an open challenge to wundercable manufacturers back in the late 80's to put their high-dollar products against basic Belden zip-cord &:coax in randomized, double-blind tests. None accepted. People forget there is also lots of wire earlier in the signal chain. Most amusing are the "golden ears" that insist their kilobuck pure silver/gold/platinum power cables will make some mystical improvement, when standard Romex is in the other side of the outlet. Snake oil salesmen are alive and well in the 21st century. (ETA: Bob Pease was a brilliant analog EE who worked for NatSemi, wrote seminal application notes and great articles in trade magazines. Like the Bob Widlars and Jim Williams and so many more, they gave light to the often nuanced world of analog design.)

John Dunlavy got a bunch of flack many years ago when he said cables make little-to-no difference at audio frequencies, and a lot of 'golden-ear' audiophiles went nuts. He found that the inexpensive Radio Shack gold RCA cables measured extremely well, better than most 'audiophile' cables costing a lot more. When the doubters made a big ruckus he decided he'd build the best interconnect and speaker cables he could using proven engineering, then they accused him of trying to have it both ways. He was simply proving a point; here's the most accurate cables ever built, if they make such a big difference then you should be able to hear it. He spent a lot of time in his showroom comparing cables doing blind and double-blind testing, and let people bring in their own cables to compare. The results were no better than guessing.

In all my car audio days (mid '90s-now), I've used inexpensive Radio Shack RCA cables and maybe occasional slightly nicer sets, but one of my favorite moments for my home audio, I was at a nice mid to high end audio store and bought a Marantz SR5400 receiver for my Paradigm Studio 100v3 towers and CC-590 center, also happened to get a great deal on a Rotel RB-1090 amp. On the way out, the sales guy said, "hey, you gotta get these RCA cables". I can't recall the brand, but they were $70 per set, so not super high end, but much higher than the Radio Shack cables I was already using. I asked him, "honestly, could you or I hear the difference between my Radio Shack cables and these higher cost cables?" He said, "probably not". So I just thanked him but passed. I do have slightly higher cost cables now, but don't feel the need to try anything outrageous. I guess some day I should do a A/B/X listening comparison, just to try. Maybe even A/B/X with and without cable risers... Ha!

Great video. "if you care about high frequencies that you can't hear, use the co-ax" - I almost fell off my chair in laughter! I think the only reason to spend more on interconnects is for longevity, some of these cheap cables break too easily or the insulation becomes hard & brittle. Other than that, as you've just proved in this video, the ridiculously priced "audiophile" cables really are a waste of money.

Hi Eddie, during all my years in RF and EMI-testing, I have seen and done lots of testing on various coax cables…. Until you get into the GHz range, well, it is debateble, much like the audio-frequency stuff… However, I have had some experience with audio-cables too…. For most part, one cable is like the other, whether it is single, double, or triple-shielded, oxygen-free copper (whatever it means),,, but I have seen some really bad shielded audio-cables too, in whick I learnt there was a difference in cables. Instead of a braided cable, some really, really, REALLY cheap audio cables, some audio cables just had the outer conductor do like one twist/inch around the center conductor. On an audio analyzer you could immediately see the 50Hz pickup on a length of that cable, if you use that cable as the interconnecting cable between a pre-amp and the power-amp, you could hear the hum… never looked further at that type of cable, it just went straight into to rubbish-bin, but maybe in the 70’s and 80’s the market was flooded with that type of cable and that is where the whole audio-cable religion came from????
@Hellhound604
@Hellhound604 13 күн бұрын
Listening to your final words, typical impedance from what I can remember to an audio-amp is like in 47k ohm… maybe the -cables should be tested at that impednace…. Not that it should make a difference????

Good day Eddie, outstanding video. This video should have been multiple videos. Lots of important information. You did not show us the baseline cable plot. You might have shown it later, but it was very confusing. When you plot the data, be careful of the frequency scale. When you plot 10 hz to 40 mhz, this should be plotted log and whe you do 10 hz to 100 kHz this should be linear. My real concern is with the introduction of phase information. You need to discuss group delay through the cable. Group delay is both frequency and length dependent. To accurately discuss the group delay to need to unwrap the phase data and subtract out the system group delay. This will give you the real phase change your looking for. Remember on the VNA, omicron 100, the phase wraps at +/- 175 degrees not at +/- 85 degrees. Thank you for your time and effort to produce these videos. I recommend not plot more than 2 plots at one time. It is almost impossible to compare traces.
@KissAnalog
@KissAnalog 10 күн бұрын
Thanks for your great feedback!! I hope it was obvious that there was no phase change in the audio band so no group delay to discuss. I am afraid if I talk too technical that I will lose a lot of the audio folks. I think you are right that more videos breaking down each technical aspect might be easier to get all the points across. I was going to do at least one more measurement video - and then a summary video. It is always tough to know how many and/or long I should make these. I don't get as many views as other videos - but I think they will stand the test of time;)

@@KissAnalog Eddie, mad props. This is an EXCELLENT video, and it needs to be shared and viewed by as many as possible !!! When you produce a series of related videos like you are suggesting, you need to label and name them as Part 1, Part 2, and so on, and put them in a Playlist so your viewers can easily watch the entire series. Such as, "Audio Interconnect Cable Test: Part 1 - Losses (Gain), Amplitude Response, and Phase (or whatever)"... ... ... "Audio Interconnect Cable Test: Part 4 - Final Summary & Conclusions" I've also noticed that you rarely ever complete a sentence with the subconscious thoughts or point you are trying to make...you always seem to stop a bit short of finalizing your sentence with your complete subconscious thoughts, which might leave some scratching their head, especially when you sometimes mix comments that are "matter of fact" with occasional sarcastic ones. And for the laymen, whenever you are "talking numbers" even in quick reference, ideally you should still state WHAT that specific number value refers to, i.e. Phase, Millivolts, Microvolts, Amplitude/Amplitude Response , Frequency, Inductance, Impedance, Capacitance, etceteras, because you are prone to randomly "jumping around" a lot. :-P It's a problem I'm plagued with as well due to some A.D.D. Sometimes you do make it clear, but many other times when jumping back & forth between the metrics you just say something like, "look guys, it's just 45", and the more unfamiliar folks might not understand what you are refering to, while you already subconsciously know what you're looking at and showing on the display or refering to. I would also try to prepare a bit more of a strict outline or "script" to follow, as you seem to bounce all over the place or back and forth repeating or rehashing things which makes your videos unnecessarily LONG. I'm not saying to strip them of all your unique character or flavor and all spontaneous thoughts (good stuff!), just try to keep things a.bit more "on track".... A lot of potential viewers simply skip over videos that are more than 30 minutes and even if they're over 20 minutes due to their busy work schedules and/or a busy family life. I'm retired and I was still reluctant to watch this video due to its length. Hope you just take all this rambling as constructive criticism. ;) Thanks again!

now you need to test for external interference to these cables, 60Hz power line and 60Hz fundamentals. that's where you hear the hum in a speaker when you use unshielded or cheap interconnects. the shielded coax like your RG400 LMR coax should fair well in noise rejection. Great video, and thank you for telling us about the Southwire multimeter while it was still cheap!

I think it’s part of the cult of obscure/expensive must = “better”. I’m also guessing most flat earth types don’t use tone controls (I love tone controls) and would rather spend hundreds or thousands on a different Cable or new speakers/amp/cartridge rather than turn up the bass/treble on the preamp a notch. Snake oil salesmen love audio! Peter Walker of QUAD fame was happy to demo stuff using orange lawnmower flex as speaker cable.

It's funny to me how many of the people claiming that cables make a big difference have speakers that aren't very accurate, and have mediocre impulse and step response, even mega-buck brands like Wilson, Vivid, Sonus Faber and numerous others. I have Dunlavy SC-V, arguably the most accurate passive speakers ever built, and John Dunlavy said they were the most accurate speaker he ever built, even better than the much bigger SC-VI that measured so great by Stereophile magazine. John said that a speaker is never going to sound better than it measures, so he spent a ton of time getting step response, impulse response and frequency response correct, and his speakers were able to reproduce an acoustic square wave with better accuracy than most tube amps.

If you have the time I highly recommend reading the Stereophile interview "Loudspeaker designer John Dunlavy: By The numbers," it's really interesting. His background was in antenna theory, and he designed the very first Log Periodic antenna in 1952, classified "secret" by the Air Force. He later designed the cavity-backed spiral antenna that was used for voice and telemetry on the Gemini rocket program, which he held the patent for. He also held the patent for felt on speaker baffles to reduce diffraction. Brilliant man.

Im looking to build a 5v-15v variable power supply with the 10a transformer. A DIY lab supply . I would like variable -constant current ,,and low current cut off, same with voltage. Good for charging lithium batteries and testing projects ,low noise etc. My question is : do you know of a chip that can do all this. I can solder SMD but have never designed a PCB. Seem those cheap lab supplies you love should have something Im looking for,but are usually switching. A whole board with chip would be ideal . I fouund a couple with google ,but figured asking an expert would be a good idea. Thanks .Brendan

Great question! Digital is even more simple and straight forward. Analog is continuous, so any change could be interpreted as meaningful. With digital - it either works or doesn't. Simple as that. Think about when we sent video (High def) through cable and it was analog - that was not easy. But then came HDMI - and the world was saved - digital made high def easy. Digital is high frequency (but not that high) and it is on or off - much easier to read.

According to audiophiles, the only valid instrument for measuring interconnecting cables is their eyes and ears. They have to look cool. We know that the amount of inductive and capacitive reactance on a cable at audio frequencies is so small that it has no effect on the signals. The level of shielding on input signal cables is the only real important thing thus lowering the amount of noise to signal levels. I may be missing something because it's true that I'm not very bright, but I don't see the point of taking measurements of audio cables above 15k.

The part I think is ironic is that cables are not born on trees - so the audiophile doesn't believe in the engineer but love the equipment that he/she designs and develops. Crazy!

@@KissAnalog Yep, that'll do ya. Or Amazon basics etc will likely do. I use Van Den Hul The D-102 MKIII, it was a different scene back then, however it worked well, it wasn't outrageously expensive, so I stuck with it.

Eddie, sorry to tell you bluntly that your testing methodology is flawed and so meaningless. You did not lift the cables under test off of the bench/ground by 4.2744609" using stands made of tiger eye stone 🤣🤣🤣🤣
