To explain a little further on #117, I am sure our friends have heard
more inner detail when one purposely leans their system, or even brightening
the top end frequency response. On a good system, one can hear the
effects down through the lowest bass regions. One is removing masking
by leaning the bass, or due to over bassing, or masking caused by
electrolytic capacitor(s) DA, or even other parts.
Of course, one can teetor/totter and over lean one's system and
lose naturalness.

Ok, so let's install polypropylene capacitors in place of electrolytic
capacitors in the entire system, removing the masking caused by electrolytic
capacitors. This will allow us to perceive the smallest frequency
response and inner detail changes, easily past -120 db. (Although not
reliably, we have tested FR down to 1 part in 11,000,000, or approx.
-140 db change). -120 db actually becomes the limiting factor in inner
detail retrieval in my system. We have to remember though that this is
a lab system, not a typical system.

DA, 7% of the music is lost to non musical nonsense in each electrolytic
capacitor used. Compare that figure with 0,02% for a polypropylene
capacitor. We actually hear more inner detail while improving the
naturalness of the music (assuming an accurate polypropylene cap is used.)
The difference in naturalness, and sensitivity is profound.

Specs sheets do not mean much when comparing components.

Virtually all audio components use multiple electrolytic capacitors.
(My lab designs do not except for the high voltage output which is
bypassed with poly caps.)

Any small change, such as bending an inductor lead, or bypassing a 2 ohm
resistor with megohms, the response and inner detail change is perceived.
