Bryston 4B NPB
The Bryston 4B is a a go to power amp for both the HiFi and music production world. Clean, crisp power with excellent control. We love to pair these with an Icon LA4 valve pre amp to add a super natural soundstage and silky smooth top end,..BINGO!, power and control without the harshness of transistor amplification.
