Bryston 4 B. Older amp but wonderful sounding with no issues. I'm not the first owner but I have used it faithfully in a pet free, smoke free listening room. 200 watt solid state. Great sound. Asking 650 or best offer. I do not have the original box but amp will be double boxed with appropriate packing materials for shipping. Manual is included. Prefer Local pick up, But I can pack and ship if necessary. I rated this a 7 due to age. The amp has a few minor marks on the front toward the bottom. These were from the previous owner and are not visible from a normal seating position.
