I've heard the Mac stuff with at the Legacy showroom and it sounded good. Bill likes the Mac very much. He uses their multiamped piece with the Helix and stereo amps with Whisper and Focus. I've not heard the Bryston with Legacy but think it would sound good as the Legacy speakers like solid state. I use Krell at my home. You might also check out Coda amps as this is one of the main amps the speakers are designed with.
