In Reply to: RE: Do russian teflon capacitors lack musicality? posted by Stuben on February 17, 2017 at 08:19:11
BINGO.
People put way too much emphasis on a coupling cap,resistor,or a piece of wire when the truth is,it's all about circuit design.If you have a bad design,the best so called components in the world can't fix that.The signal path tweaks such as coupling caps and resistors are nothing more than fine tuning. The real change comes from the power supply upgrades as that's what an amplifier is.A DC power supply that we modulate with an AC signal.

With all that said, you can hear the differences in passive devices, particularly caps and output transformers of varying build and quality. I interpreted the term "Musicality" as a system attribute. I have to admit, I've never heard the term used before..:> )

BTW, I have used the Russian Military Teflons.
Very Nice results. I like em..

I agree! The whole is the total sum of the parts and part of the parts is the circuit itself. I was never a believer that one piece of wire, one cap, or one resistor can make such a difference sonically. I think or I should say, I believe there is more to it than just one single entity.
Exactly Paul
A lot of times I have put in particular coupling cap or used a particular cable and what happens is,we get fooled by the sonic change in a particular area of the spectrum.Our subconscious responds to it as a massive change when it's not and you notice it after periods of listening to familiar music many times.

People say they hear things when a change is made. But do they really or do they just want to believe it?
The best way to settle that is by double-blind testing. And be always suspicious of those who claim DB testing is not trustworthy--they usually have a vested interest in claiming that!

The problem is that snap judgements are just as problematic as unblinded testimony. To do it right, you'd need for the tester to be blinded for several listening sessions lasting several hours and listening to a variety of musical genres, using capacitor A (or whatever component A), for example. And then to go through the same process, blinded, using capacitor B. And then ideally back to capacitor A. After THAT exhaustive process, I might believe my own ears (but not necessarily someone elses). We think we know and can remember what something sounded like after 5-10 minutes, but we are delusional.
Agreed. External validity matters.

Why not try training the ears like the expert wine tasters who can get down to village level in the origin? I am quite willing to wager heavily that the learning process is not blind.

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
I don't know how true this is but a good friend and well known tech in my area said to leave the UF as stock or close to it as possible. He realizes back in the early days of stereo the caps were limited in what was available but the circuit designers knew what they were doing and did it well, despite the lack of quality in parts back in the day. Can improvements be made? Very suggestive answer but he did say that when modifying values keep in mind the T/C's(time constants) and messing with them can make something sound out of balance(to bassy, too much highs, etc.). The idea was a flat response but is flat always the best way to listen? Thus either tone controls or messing with parts values to create a different sound.
