RE: Film Capacitor Orientation Question

Posted by tube wrangler on July 16, 2021 at 09:21:38:
A SET is different from a p/p, or a diff-amp.

The SET, if built in a transparent manner
(power supply caps not too large, excellent
layout, good grounding scheme, use of brass parts,
silver wiring, use of circuit standoffs where needed,
careful avoidance of excessive plate currents-- even
to the point of slightly lessening full power linearity--
then such an amplifier will easily reproduce everything
you can throw at it-- not just in usable
frequency response, but also, in fast rise times,
and in shades & colors of music, micro
and macro dynamics, and depth of and placement
of multiple-layered sonic images..

That kind of attention to detail will allow
reproduction of nuance on a level that other
amps can't, and do not, match sonically.

In such an amplifier, it becomes obvious
when a high quality capacitor is installed
backwards.

IAR/TRT is one place where this has been
discussed over the years, JACMUSIC.COM has
linked to others, Michael Percy Audio has
extensive knowledge of this subject.

Dynamicaps, Mundorf Silver/Oils, etc., have proponents
that install the caps one way, while another guy
might purposely install one backwards, while trying
to obtain better overall tonality, not quite
realizing that if the cap is installed correctly,
he won't be getting any wild effects, but will
instead, simply get the best that the cap can offer.

To each his own.
