Bryston's are awesome with Maggies, but IMO, Nelson Pass, rules! If I won the Power Ball Lotto, I would select almost any speaker around Pass Labs. Yeah... Pass Labs is pricier, but what the hell, if you won the lotto.
I had the pleasure of trying out a pair of the Magnepan 1.7 with an old set of Threshold SA 1 Optical Class A monoblock amps and of course my Pass Labs X350.5. Both amplification set ups being designed by Nelson Pass. I could not find better amps for the new Magenpan 1.7s
