Given your speakers don’t present an overly hard load, have a tendency toward brightness in the treble, and your budget I’d consider a Clayton Audio S40 Class A amp. There's also a Plinius SA103 for sale in your price range if you feel you need more power. Not sure the Bryston will do much to tame any perceived brightness you may have, so Modwright would probably be the better choice of the two. Best of luck.
Bryston vs Modwright?
I'm looking to replace my old power amp with a new one, in the $4500-5000 range; I'm running an ARC ref 5 SE that I got from a friend, and will be driving Dali helicon 400 mk 2s. I have been thinking solid state to complement the ref 5 SE, and have been exploring the Bryston 4bSST2 vs the Modwright kwa 100 SE. Anyone have experience with either or both of these amps?
