Bryston 3B ST or McCormack DNA 1

I've owned both and I would have to give the nod to the Bryston 3B-ST. The 805's are a highly detailed speaker that like a highly transparent signal. I agree with the other postings in that the DNA1 may gloss things over a bit, resulting in a smooth polite sound. The DNA1 may be better for a speaker that has the propensity to sound bright. I've tried the Pass Aleph 3 as well with my Nautilus 805's and they sounded gorgeous except for that last ounce of bass detail and refinement.

Bigdave you hit the nail on the head regarding DNA-1 with brighter speakers. It's a really nice matchup with my good ole' Klipsch, which are pretty revealing & can sound on the bright side. Careful system tuning is a must with these horns, & the "smooth/politeness" of a mosfet amp works very nicely. If the Bryston is bipolar output topology (I dunno 'bout that) it likely wouldn't work so well into a brightish speaker.

Try a Belles 150A. It is between the 3BST and DNA1. A little brighter and more accurate than the DNA1,but warmer, smoother than the 3B ST.

I have a Belles on the way to my house right now. Will report back, although can't vouch for performance w/B&W's which are flatter/smoother than my spk's. Should be interesting

Thanks all. Just wanted to let you all know that I did purchase a 3 channel Belles 150A.
