Coupling caps suggestions

[multi]

OF course Audiophile caps sound better!!! They cost more!!
Recently a friend asked me to fit some Mundorf .56uf caps to his amp.
I always test caps before fitting; I got these readings for caps labelled .56 1%
.39..49,.. .56… .5..
Imagine what that lot would sound like in a push pull amp?
I will stick to Ero, Wima. I have never found caps so far out even cheap Chinese ones. Ero and Wima always measure very close.
So always test your caps

I think that is good advice Phil. Every batch of Russian PIO I've got usually has one cap that is double the capacitance of the label.

I cope with the first however...in what way does tolerenses affect sound? It does not matter whether the coupling capacitors have 1 or 10% of tolerance. Only in tuned circuits ... RIAA, tone controls, etc. .. does tolerances mean anything.

The subjective discussion about cap sound is nauseating to me.

Which tempts me to mention: a couple of weeks ago i spent a good few hours listening to caps in the PS of a dc motor. The caps supplying the raw dc before regulation... Nauseated?

I'm always intrigued by folks making the claim that people will hear what they want to hear. I know of numerous occasions where I've been in an environment where I've been expecting a big improvement (due to boutique parts, or high end components, or perceived value, or reviews) where I've been decidedly underwhelmed and dissatisfied, and conversely numerous occasions where I've been expecting things to sounds pretty unimpressive and been flawed by the quality of reproduction.

Seems to me that if I'm hearing a change, it's due to what I'm hearing, not what I'm expecting.

Please don't confuse people's simple beliefs. Surely there has to be something which gives you a cue for your likes and dislikes. Maybe it is the capacitor's colour... shape... tactile feel. Whatever it is, it cannot be the SOUND

Don't forget the "story" and the corresponding price. These are huge influencers of the brain.

And, at times, there's also the extremely inferior performance of an expensive "audiophile" capacitor which, because it does actually sound different due to its defects (typically moisture-laden paper dielectric and/or loose windings), is selected as "vastly improved."

The guy used grey carpet, he was a sound guy and amp tech. He said it stopped the speaker cab colouring the sound.

Yep...you need a grey carpet to do that!!!!

Oh yes, thousands of humans living on different continents with different cultures hearing the same attributes on resistors, cables, caps, transformers etc but they are all fooled but you smarta... got it right - oh please....

In other words, the same "evidence" which "proves" the truth of astrology, alien abductions, dowsing, ESP...

Its sooo easy to proof that millions of people, all believing the same thing, can all be wrong. Proving that the fact that millions of people belive the same thing says nothing about it being true or not.
You guys want me to go ahead?

Well you don't want to colour the sound. Just think what deep purple would do!

Gee it not like going to war over it or is it ? Proof only applies to Burbon for most people .

Nah.... somebody has to do the dirty job, as long as it's not me.

Apparently my sarcasm got lost between the lines. Will try harder next time.
