Do equipment stands have an impact on electronics?


Mechanical grounding or isolation from vibration has been a hot topic as of late.  Many know from experience that footers, stands and other vibration technologies impact things that vibrate a lot like speakers, subs or even listening rooms (my recent experience with an "Energy room").  The question is does it have merit when it comes to electronics and if so why?  Are there plausible explanations for their effect on electronics or suggested measurement paradigms to document such an effect?

Well, he’s wrong. And you (and he) are the ones who don’t get it. And Argument From Authority never impresses me. But you don’t have to believe me. Honest, I don’t care who you believe. But if you're serious about understanding audio, you’d do well to cancel your subscription to the audiophile magazines and join the AES instead.


My two cents as a 40 year technology professional who only dabbles in audio as a hobby these days is that its always all about how noise and distortion is effectively kept to a minimum and more ways than ever to tackle that beast cost effectively these days.  No individual or entity has exclusive rights to a secret sauce.

The rest is mostly personal preferences which differs for each but has nothing to do with science and technology solving a problem better for the most part.

Also I will cast some lots in Ethans camp though its a bit narrow-minded and say that room acoustics are perhaps the first and primary thing to consider before during and after buying any home audio solution. If you get the acoustic fit into the room right to meet your needs its pretty clear sailing these days from there.

... Yes, many fabulous recordings have been made on old school analog equipment. But that equipment has lower fidelity than even consumer-grade modern digital converters. So again, the perception that analog recordings are more "lifelike" than digital is a psychoacoustics effect caused by the addition of distortion.
This is an old, tired and transparently silly argument. It's the logical fallacy of causal reasoning.

If distortion were the key to the preference for analog recording, then obviously more distortion would only improve those recordings. But of course, those who've made the best quality analog recordings typically did so while working to keep those distortions to the lowest possible level. You have simply confused cause and effect.

Honest, I don’t care who you believe.
Oh, you care very, very much ... so much so that you've resorted to profanity-laced ad hominem attacks here that have resulted in multiple deleted posts.

Man, I’m still surprised by the amount of hubris out there.

I’ll never forget the first time I heard a direct-to-disc LP, the second Sheffield. That label’s recording engineer Doug Sax went back in time, resurrecting recording without an electronic recorder at all, cutting a lacquer directly from his mixing console. The transparency, the "aliveness" of that recording, was astounding. It showed how much distortion was being added by the recorder itself.

The bypass test, in which the component being tested is inserted into the reproduction chain, the audibility of it’s insertion being listened for, is the ultimate test of a components transparency. That audibility will vary according to who the listener is, it has been established. The "better" the listener, the more audible the component. Perhaps Kavi Alexander has a much lower tolerance for digital and/or solid state distortion artifacts than your average AES member. To claim that his recordings sound "good" because they contain pleasing "musical distortion", when one has not even heard one of his recordings, and further that Mr. Alexander is "wrong" for preferring analog to digital (and tubes to solid state!), is not only ignorant, but arrogant.

The lack of humility is a very unflattering trait.


The very definition of high fidelity is a flat response and low distortion. Yes, many fabulous recordings have been made on old school analog equipment. But that equipment has lower fidelity than even consumer-grade modern digital converters.
Ethan, when you say that a person 'prefers distortion' I assume that you know that the ear/brain system converts distortion (unless outright, as in clipping) into tonality. This is why a lot of tube equipment sounds 'warm' or 'rich', because of the presence of the 2nd harmonic. But this does not have to be made by tubes in particular, solid state can do that too (the early 70's Sunn solid state instrument amplifiers are good examples, as is the old AR amplifier). Much also depends on topology.

For example, you can prevent tubes from having a 2nd harmonic simply by employing fully differential design from input to output (which is how a lot of transistor gear is designed).

Regardless, the admonishment I am offering here is to be careful about attempting to place all the 'deplorables' in one basket! The issue is that the human ear/brain system is relatively insensitive to lower ordered harmonics (2nd, 3rd and 4th) while it is **very** sensitive to higher ordered harmonics- so much so that it can detect them when often test equipment cannot. The reason for this has to do with evolution and the fact that our ears use higher ordered harmonics in order to gauge sound pressure (this fact was first documented by General Electric about 1965) and is very easy to prove with very simple test equipment (I have documented how elsewhere on this site).

So if the ear is insensitive to a certain distortion, does that mean that if that distortion is present in a given bit of equipment, that it is heavily distorted or not? This refers to a comment I made earlier where I mentioned that the audio industry tends to be about 40 years behind where it should be because for the most part it ignores how our ear/brain systems perceive sound. Certainly our ability to detect sound pressure has to be one of that more important aspects of that perception!

So where I'm going with this is that just because analog systems have more distortion to which the ear is relatively insensitive, that is not saying the same as its 'less high fi' when the succeeding art tends to have **more** of the types of distortion to which the ear is far more sensitive! In essence, as far as I can make out, digital fails because generally, while having lower distortion on paper, in practice that distortion is far more audible to the ear (which is converting it to tonality). And since this is all about stuff we hear rather than what we see on a bit of paper, I don't think its correct to say that analog is less 'hifi'.

What is more accurate is to say that analog, despite having greater distortion, more closely follows the rules of human hearing than does our current state of digital. BTW this is also true of tubes (and certain transistors) as opposed to transistors in general.

I get that it takes a bit to get your head around that 2nd to last paragraph! If you look at how stuff measures on paper, in essence the wrong things are being measured. So as a result, if the paper spec is your guide, you miss something.

This is why there is an objectivist/subjectivist debate, a tube/transistor debate and an analog/digital debate.

BTW I do not regard myself as a subjectivist- I'm an objectivist (if such a thing is really possible- philosophers will tell you that it is not) that feels that to ignore aspects of our hearing that our testing ignores is not wise.

This is why tubes and analog are still around. The market keeps it for a reason, and high end audiophiles are not that reason! They represent a tiny portion of the marketplace that keeps this stuff alive.
