SIMAUDIO 400m vs Bryston 7bbst2

HAve one heard the other ..might want to switch..any comments ..thanks
I have a SIMAUDIO MOON the W-5 limited edition, and

all that I can tell you is it is very musical from top

to bottom capable of driven any speakers from 8 ohms down to 2 ohms it is the best power amp for

the money nothing come close.
Simaudio 400m had a great review in Soundstage I believe, but not much else written about it. I am also very interested in a pair for my Revel Salon 2 (which is what the reviewer used). Need power and warmth, and the 400m's seem to offer both. Let me know what you find out or if you hear them.
