Used. A rare gem from Bryston. Pots and connections cleaned and tested. Unit sounds excellent. Left main-out plug can take a twist of the RCA to seat the connection properly. Once seated it's perfect. It should be an easy and quick resolder job for a hobbyist or tech, but it is something to be aware of before purchasing.
