Happy New Year to All:-)

It would be interesting to know how many on this
group think/find that:

a) capacitor "upgrade" results in a clearly audible
improvement.

b) a capacitor is a capacitor, and all caps of the same
value and voltage rating sound the same.

There's rather more to a capacitor than just value and voltage rating.
Otherwise there would be only one type on the market.

Yes indeed. I was trying to start the thread off in a simple manner.
Please add as many variables to the equation as you wish.
Do you have any opinions/experiences of the upgrade path?

Happy New Year Iain and everyone..

a) When I upgraded my Lumley monoblocks I modified one with Jensen copper &
oil caps and compared modified to unmodified The moded one came up tops
every time according to five enthusiasts but my back hurt afterwards with
the changeovers :-( The only way to know which amp was which was by
removing the base cover which we did expectantly after the event...I
breathed a sigh of relief that it was the moded one as those caps ain't
cheap.

But hey, we must have been imagining it all as we all know there is no
difference between competent amps, cables, CD players, components, stands,
spikes, cones :-)
Had a great late night session last night till 5am, the music just sounded
better and better as the night progressed... which may have been due to
certain beverages :-)

Not really. I tend to favour polyester layer for audio path stuff.

Well I presume that the closest approach to the ideal capacitor is
a pair of parallel plates in a vacuum! A bit bulky for anything more
than nanofarads though!

Hey, what limits the voltage on a vacuum-plate capacitor? I should totally
know this, but above a certain voltage for a given separation, is there
any kind of breakdown?

So what are your thoughts/experiences regarding upgrades?

Thanks, but this doesn't mean much to me. What is "dielectric strength"?
And presumably that is per (some unit of length), is it?

I don't understand the meaning of the legend in the middle of the graph that
seems to say "olts DC / MII". Uh? I assume it should say "Volts", but what is
"MII"?

Does the (hard) vacuum break down when the electric field exceeds
X volts/metre? When that happens, what, well, happens? I can't imagine there
is a visible spark, because in the ideal case, there is no gas to glow.

Excuse my ignorance, but at least I acknowledge it!
