On balance, I would recommend the Bryston amps over the B&K's: better sound quality, better build quality, and a far superior warranty (20 years). If you decide to go with the Brystons, and you have smaller (i.e., not full range) center and surround speakers, you might consider the pairing the 4B-ST with a 5B-ST rather than 6B-ST. The 5B-ST has actual power output of 150 wpc, which is usually more than sufficient for the center and surround speakers. I have been using a 4B-ST and 5B-ST combo and am very pleased with it -- fine sound quality, and more than enough power.
Which Amp Is Better ? ?
I'm contemplating replacing my 5Ch.Amp on my system and going to separate 2Ch.& 3Ch. Amps. My choices for now are: Bryston's 6BST & 4BST OR the B&K Ref. 3220 & 2220 ..Any thoughts on which may be the better choice ? Also, any further suggestions on other Brand/Models would be appreciated ! Thank You ! Larry
