OK, I ran some diagnostics on the PAS. Tubes all test >100%. Voltages are where they should be. No high ESR in power supply caps.
Listening: the PAS sounds gorgeous, but that's really the problem. It's gloriously euphonic, but not honest. It adds just a bit of compression. It's like one of those TV shows like CSI Miami where we know that everything is run through filters to make everyone look good.
Switching back to the passive volume control, some recordings are less pleasant to listen to, but the instruments sound more like I know they do when heard live. Bass guitars and drums are much more defined.
