Capacitor Bypassing

[jt]

I read this on Auricap:

Do not use bypass capacitors in the signal path. A single capacitor for DC blocking / AC coupling creates a simple path with one time constant. The signal quality will be compromised if a bypass or multiple bypass capacitors are added to a signal path capacitor. Bypass capacitors were used in the past to bypass low quality film capacitors or electrolytic capacitors. The bypass was the lesser of two evils. With the advent of better quality film capacitors the need for a bypass capacitor was eliminated. Bypass capacitors create multiple signal paths with multiple time constants. These time constants are very short but they can still be heard as a smear or overall loss of focus.

What do you guys think?

I agree with it. Did the experiments nearly 20 years ago with another JT - John Tucker. We both thought the transients were smeared when a bypass cap was added to a coupling cap.

I say try it.... I have used both in my 1st order high pass on my Maggie's. I have heard improvements in some cases and degradation in others. Ex. Obbligatto's did not improve. AmpOhm p/o did. I have had my Mundorf s/o in and out of the circuit several times now with the Mundorf EVO's. They are now soldered in.
