86 dB sensitive speakers in that 4 to 6 ohm range, and a good sized floor stander at that. I bet that Revel speaker needs a high current amp to drive it. From my *general* listening experience, Pass Labs amps, especially the dot five and dot eight series bring the dynamic goods to the table. Plus, the air, space, layer separation, and that wonderful midrange bloom that lights music from within with Pass equipment is good stuff. I've listened to some Mc gear, and while it seems pretty good to me, it seems to have a little bit more laid back character; it is not bad to say the least. I think getting a 350.8 will solve your problems as that amp doubles to 700 wpc at 4 ohms. That's some beans right there. In my experience, Pass amps can be picky, and there is definitely a synergy that comes to life when a Pass line stage is paired with a Pass amp. While this might be apples and oranges with your situation, I have Pass Aleph 1.2s paired with a X0.2 three box Pass line stage behind it and it's glorious; prior to the X0.2, I had a Sonic Frontiers Line 2 behind the Aleph 1.2s. While it sounded *okay*, even with getting some more expensive tubes from Upscale Audio (when he ran it [the business] out of his house...), it still did not *pop* like equipment of that caliber should. When I sprung for the then newly inrtro'd X0.2s, and let it burn-in, holy Moses, it's like someone pulled off a veil and those big Class A monos made my Von Schweikert VR6s sing and soar very high! I mention my experience because you have an Anthem (the old Sonic Frontiers) line stage and you are thinking about getting a 350.8 Pass amp. In any case, happy hunting as the saying goes.
