Arnyk, I have to define world recognized audio designers as something. 'Master', 'Expert', or 'Recognized' or something like that is appropriate.

"World recognized" infers that much of the world would know of these people.

Tain't so, and it is getting to be less so as the boomer generation dies off or at least loses interest in high end audio.

But thanks for providing the evidence that personal fame is a strong value in some people's lives. IME, not a universal trait.

Well as I point out to the wife. Her ancestors were building amazing temples whilst mine still handn't worked out that chimneys were a real good idea and still thought bullsh*t was a great building material.

"Count Andrea Ludovici's ancestors were ruling Venice even then. Mine were raiding English cattle over the border from Scotland, wearing nothing but blue paint beneath their plaids. If they even bothered to wear their plaids."

Well some people know about audio quality and others don't, and some people even recognize the names the master designers over the decades.

I find the connotations of you now referring to your self as a master designer rather disquieting... Again it is reinforcing the esoteric audio belief system, with "masters" who hand down nuggets of wisdom to their acolytes... no proof required:😱

the point of the discussion
Ap user: resistor sound is BS
JC-CH audio design: passive matter
Diy (at last I and Jacco) resistor have a sound

Actually the "OBJECTIVE" crowd (AP users and others as well) have pointed out passives do matter and standard practice when going any electronic design is choosing the correct passive, at the correct tolerance and de-rating it (or us multiples) to ensure that any negative effects are catered for and will not occur during normal circuit operation (thermal with resistors is one example, do not use at greater than say 25% rating in critical areas). This is common practice in most areas of electronics.

Don't forget that they also realise that a resistor has associate capacitance and inductance and model accordingly. Or as was once said to me 'all components have extras'.

Agreed.
In some ways the traditional engineers were miles ahead of most amateurs in this regard.

For example, in terms of things that actually make an audible difference, there was nothing, nada, zero in Marsh and Jung's allegedly ground breaking capacitor article that was not conventional wisdom among experienced traditional analog designers. One of them was National Semi's highly regarded Robert Pease, and he even published an article about this for a well known electronic engineering magazine, which was of course ignored by audio's high end press.

It would have been very hard even in in the days of the Marsh/Jung article, to find audio gear from good pro audio or consumer audio manufacturers that misused capacitors in ways that actually compromised sound quality.

When I learnt circuit theory and its background the names we learnt were Ohm, Watt, Kirchoff, Ebers-Moll, Maxwell, Poynting, Fourier. Did my teachers omit some I should know?

Hmm. The answers you might get to that question could lead you to people who wish you to ignore or even contradict the names you've already mentioned. What would Watt and Ohm have to say about class A power amps? ;-) We can only speculate. The possibility of corpses attaining high rotational speeds in graves exists. ;-)

I have to admit that among more modern audio authorities I think I have learned a ton more valuable audio information from people like Fletcher, Munson, Zwicker, Fastl, Vanderkooy, Lipshitz, Toole and Olive than others whose names may be currently more proximal to this discussion... ;-)

we know that 1w resistor sound better , we use 5xW

Wrt _audio_ quality, listening is important; did you learn what to listen for? Did you learn enough about proper sensory testing? 😉
Click to expand...

Based on the relevant papers I've been able to review, the sensory testing was either absent or highly flawed.

Got any good examples?

BTW one key to sensory testing is that the effect to be sensed be above the threshold of reliable perception. Got any modern references showing this to be true?

Rather than leaving the table empty, this document may help:
