I'm done with proving that somebody is wrong or I'm right (it's not exactly the same thing) on the Internet
It takes considerable effort to do and doesn't gain anything for me, because the end is always the same. It's silence. So I just present what I know and if one doesn't believe me it is his right. But as a consequence, I have a right too. A right to not care about it
Regarding the subject, let the sh* hit the fan. Shunting lytics with PP works and the result is easily "nullable". I use direct-coupled ADC and direct-coupled DAC for tests. Maybe DC is not that important, but mine are DC, so I just present my condition. Audibly, the effect is more prominent with fast-transient stereo tracks. I use oversized Pana FR/FC lytics and Wima 0.033 uF MKP-2 caps.
