FS: Bryston SP1.7 processor/pre-amp 19" silver
Posted: Mon Sep 23, 2019 11:22 am
Moving house and downsizing system so up for sale is my Bryston SP1.7 processor/pre-amp – silver 19” rackmount 230V version.
In excellent cosmetic and operational condition.
Basically, it’s a highly regarded Bryston BP25 stereo pre-amp (same analogue circuitry), but with DAC/surround capabilities in a single box with remote.
Looking for €500 ONO. Cash-on-collection in Dublin (or via bank transfer or paypal friends and buyer pays shipping from Dublin).
Specs/reviews below.
Pics can be found on my wigwam and avforums ads. See: https://hifiwigwam.com/forum/topic/1360 ... nt-2437853
