Bo1972 --
I prefer Pass labs over all other solid state. [...]
To each his own, and many factors could have influenced my sonic impressions where Pass Labs gear was involved, but on several occasions with these amps, with varying other equipment, I've found the overall sound somewhat dull and a bit lifeless. Certainly highly resolved, easy on the ears and well-balanced, but often lacking a sense of "snap," immediacy and being ever so slightly too laid-back and easygoing; in a sense, too "hifi-ish." Haven't heard their latest .8 series, so I can't comment on those.
