I can hear the difference between silver and copper in interconnects, speaker, and power line cables. I know of many people that can also hear the difference. I have also heard the difference when a Denali in used in the power path. Do you think all diodes sound the same?
AC does not "sound" as long as there is no "hum" in your sytem, because AC = hum. Period. Diodes do not "sound". They just rectify some AC into DC. The "sound" comes from the signal (music), speakers, crossovers, room modes, air temperature and moisture (and in some cases from the drugs used to change the perception of sound). Good amps and their transistors / FETs etc... also do not "sound" as long as they are not overdriven, since the distortion is way too low to be noticed among 1000 times more distortion from speakers, crossovers etc... (with the exception being some tube amps that are intentionally built to color the sound.)
That takes me back, didn't even have to turn the stereo on
Perhaps you can see Rick how I can easily dismiss what you say as twaddle
Wow, some interesting posts. I guess all that injuneerin stuff I did wirin dat big ol thigamajig was useless. Wires iz wires, diodes is diodes..
Rick, are you some kind of diode guy?
I guess the bridge diode in my amp cannot gate the hf audio currents into the line during conduction. Who da thunk.
And I can just drop snap recovery diodes in all my low level equipment.
Oh, let's not forget the perfect lyrics that don't drop off capacitance with frequency, jelly roll what?

However you look at it, DC does not mean steady state.
Yeah I'll buy that Lordy Be, lest you put my Pompey self into a Kelvinator!
The problem with this statement is that it's wrong and there are plenty of measurements on here to show that. All good science.
Yes I am, if you have or can find a copy of the magazine "The Audio Amateur" the first issue of 1994, page 26, you can read my article on diodes.
I did a lot of work with Walt Jung back then on power supplies and we found that everything could change the sound of power supplies. I know that just about everyone here does not believe this, and I am ok with that.
And I know more people who don't. Since this is an internet relativism metadata vote we win.
Rick: I assume that you have read the work of Mark Johnson done in the 21st Century on this? Linear Audio | your tech audio resource
Precis: One resistor and one capacitor and all diodes end up the same.

No, what I was claiming was valid ... just that it's been 45 years since I've done the atomic physics of electrical conduction so writing the explanation is a little beyond this tired brain!
You had a stereo back then!
My system was mono till after Sgt. Pepper.
The mono mix of Lucy in the Sky with Diamonds still sounds the best!
Fairy nuff, I'm still interested to know as I never got further than viewing metallic conduction as a big sea of electrons nudging each other about and depletion was only a term used in semiconductors.
I use Rick’s selection criteria for low noise diodes and CLC filtering and then apply Marc Johnston’s Quasimodo jig to optimize CRC snubbing of the transformer and positive/negative bridges. Then I can hear copper/silver wire differences ...............................
I kind of like your stances about copper, silver, stones, raisers, diodes, etc... You can hear them all, good for you, although you must not be so happy about the amounts you have to spend to make your audio experience enjoyable.
At least you are not following the frustrating example of some your Golden Ear colleagues, trying to scientifically explain what they hear. Quantum effects, Maxwell daemons, perpetuum mobile, etc... nothing is off limits in their attempt to justify what is ultimately a personal experience (or improve sales). You hear what you hear, good for you, if anybody wants to follow your experience, so be it.
Yes, every element/compound has it's own characteristic 'sound', some pleasing and some not, and some 'play nice' and some do not.
The problem is that 'just about everyone' believes that the above is not possible.
I asked questions in lectures and got told forcefully that cables/wires 'are not and cannot be directional'.
Because of this 'advice' I chased a channel imbalance problem for ages until I found the culprit....turns out shielded cable used as phono interconnect can be directional and was indeed the cause of the problem in this case.
Since then I no longer subscribe to this commonly held belief that cables 'cannot be directional' and have proven the opposite many times.
Averaging type meter/analyser will not reveal this directional characteristic, but ears can and do.
