Anyone compared BAT Rex vs. Atmasphere MP-1?

Maril555, my MP-1 is a modded MkII that replaced a BAT VK5i and VKP10. The main thing about Atma is the sense of wide open bandwidth and agility, as compared to the mellower & prettier sound of BAT. However at CES BAT REX components were fast on their feet, effortless, yet a bit fuller in embodiment than I hear at home. Of several exhibits this was the only one that had convincing synergy with Shashas. In other contexts at THE Show I heard MP-1 Mk III sound remarkable with Classic Audio Reproduction field coils and VPMS. It's a close horse race.

I heard MP-1 in the same room at THE Show with CAR speakers, and liked the room very much.

i agree with dgarretson that mp-1 are moreso than most any at being wide open, add they are great at chameleon. I've had loads of fun rolling tubes and finding what I like for certain disks to help "flesh out" or even "thin out" the musical presentation, at my discretion. great unit.

Ralph- I just saw (for the first time) your MP-1, but with a stunning brushed alum. finish. IF you had that available 2 years ago, I would be a proud owner. Well, hopefully my next preamp. Impedance wise, is the MP-1 a good match for Burmester 911 MK3?

Talk2me, There is no power amp made that has an input impedance too low for the MP-1 (it can drive 32-ohm headphones directly from the same outputs that drive the power amps). The Burmester is completely balanced, so no worries.
