I was hesitant to ask since I didn't want to open up this can of worms again.
So let me start off by saying this: I know a lot of folks believe that skinning caps cannot have any effect on the sonics. Point heard. I understand where you're coming from and the basis of your argument.
I have, however, experimented with this myself and I've found that sometimes, not all the time, skinning the electrolytics can affect the sound of a system.
To keep this from turning into a "Can to!," "Can not!" argument, I want to simply ask those who have tried it and have heard a difference this question:
In any instance, did skinning the caps result in a sound that you found undesireable?
Most accounts from people doing this are positive, but I doubt if any sort of tweak or modification, however valid, can be universally positive. I'm wondering if doing this has resulted in a sonic change that you've found negative, and if so what the characteristics of the changes were.
Thanks,
KT

What is 'skinning'?
Is this covering the component in some sort of conductive wrapping and earthing it?
Please clarify this for me. Thanks

Thank you for that interesting information.
I might do it to all my H.T. and bypass caps then, as I'm almost sure this modification will show tremendous sonic improvements!!!

Even better you can order a range of caps from me...that were formerly Black Gates...but I've skinned them and you can only see the aluminium now...but they sound even better. I then paint the alu with shellac! Sounds sublime... 😉
Want some? ...100$ a piece for any value.
Enough joking now..I skin mine.
The reason : Just like Nils Bohr said when people asked him why he had a horseshoe above his door for luck...people said: "you are such an intelligent man..surely he did not believe in such nonsense" his answer was brilliant, it went something like this : "I've been told that you don't have to believe in it for it to work" 😀
Hi KT,
Yes I have done this - I produced a 'cottage' mfg amplifier in 1990 called the Eidetic here in Australia using multiple parallelled PS caps, all 'nude'! It was very highly regarded, maybe a landmark product for a number of reasons.
It did seem to make a difference but the main object was reliability! The physics of it dictates that elerctrolytic lifetime is related to temp elevation and that shrouding the things in plastic can't help! I also used multiple parallelled caps to spread the heating ( in the ESR).
Having said that it appears that the lower ESR that heating causes is a dependency of some, especially cooking chassis, despite the dramatic decrease in lifetime from say 2000hrs to 200hrs.
I was emphasing good design being about sustaining performance for a good lifetime.
Cheers,
Greg

Now that this has gone tech. I could add that adding heatsinks to PSU caps is also not the worst idea.
