Re: Excellent interview. Should be required reading for all audiophiles.


I used the O-scope as an example and I am well aware that the test equipment that is available now has much higher resolution. It still does not give us the whole picture.

Well that depends on just what you're defining as the whole picture.


I don't know about the "Hearing and actual perceptions" bit. Having been involved in audio for over 25 years...I know when I hear a difference be it for the better or for the worse. If I like it, I keep it, if not...out it goes. I don't need measurements to validate what I hear.

To me, "hearing" implies perception arising from our sense of hearing, i.e. via our ears, and something which is an actual audible stimulus. I make this distinction because it's a rather well-established fact that our perception of how something sounds can be affected by things other than our sense of hearing. In other words, we may subjectively perceive a difference even in the complete absence of any actual physical difference.

As for going with that which sounds best to you, regardless of any measurements, I've no problem with that at all as that's essentially the same approach I take myself. However I don't assume that because something sounds better/worse/different to me that it's due entirely to some physical change resulting in an actual audible difference.

But that's precisely what many people do, and while we don't know everything, given what we DO know about human perception, I don't consider that a valid assumption, at least not at the levels we're talking about here.


The whole point I was trying to make with you when you implied that "using your hearing to gauge an auditory change was up there with aligators in the New York sewer", I took that as you need measurments to validate what one hears. If that is not the case then I apologize.

Apology accepted, though not necessary.

My comment only spoke to the notion that our ears are the most sensitive instruments on the planet. They're simply not. That's all I was saying and wasn't intending to imply anything further.


Measurments only reveal the technical side of a circuit. A good example is negative feedback in SS amplifiers. Yes it is a necessary evil but it also strips away the harmonics that renders the music "sterile and lifeless".

Hmmmm. I've yet to see any evidence that negative feedback strips away any harmonics. At least not any harmonics that were originally present. How could it? Negative feedback doesn't know a harmonic from a fundamental.

Now, it does strip harmonics in the sense that it linearizes a circuit and reduces the harmonics that the circuit would otherwise add to the original. Is that what you're referring to?
