Are you saying that electrolytics are or aren't audible ? I can't
figure that one.

Think what you like pal, I've grown utterly tired now of this thread,
and
your tedious replies ...

Show me a capacitor ( other than those I've mentioned ) that distorts
will
you !

You sound very gullible to me.

Please don't descend into trying to trade insults. As I said, believe
what
you like.

It's not a question of believing. That's what the audiophools do.

I've actually gone to the trouble of measuring ! With Audio Precision test
gear
that has a generator residual THD of 0.0007% ( -103dB ).

Not a single film capacitor of any type I've checked has any distortion
whatever. Nor would I expect any from first principles.

What's your experience in the matter ?

Did I actually say that any capacitor per se had distortion ? The problem is
that you have such a bee in your bonnet about this relatively minor point,
that you are either not listening to what I am saying or deliberately
misconstruing it in order to continue with this senseless lambasting.

Clearly there must be differences between different constructions of caps
from different manufacturers, otherwise, there wouldn't be different types
with the same value and voltage rating, and different price tags. You
wouldn't for instance use a cheapo cap intended for decoupling purposes, as
the timing element in an oscillator. If you wanted it to last, you wouldn't
use a bog standard cheapo electrolytic in a switch mode power supply. But
there's my point. Manufacturers do - not because the designer wanted them
to, but because cost dictated it. This results in inferior performance of
the power supply over what the designer initially intended, and ultimate
failure.

You may also be getting confused over what I am treating as 'distortion'. I
am including anything that not only makes a piece of equipment deviate from
the ideal, but also from what the designer intended. If *any* substituted
component on cost grounds causes any deviation from what the designer
originally measured on his development model with the components he used and
specified, then this under my definition, is distortion. It need not
necessarily result in mishaping of the output waveform in any way that would
normally be considered as distortion, which may or may not be audible, but
could include unwanted phase shifts or gain non-linearities.

You're right. I don't spend my time measuring caps with high precision
generators - it's not my job. I leave such things to people like you, and
read about it later. I make judgements based on what I read, and who wrote
it. That makes me neither gullible, nor any kind of 'phool' - audio or
otherwise. Enough time has now been wasted on this. I have made my position
quite clear in as many different ways as I know how, and since no one else
has joined in with you to have a pop at me, I can only assume that they
understand what I am saying, and don't disagree strongly enough to find it
worth bothering. Considering some of the stuff you have come back with, I
think you have a cheek snipping " rest of rant ". I associate ranting with
the nonsense that goes on over on uk rec audio with this sort of thing.
Perhaps you should concentrate your efforts over there, where you must feel
much more at home ...
