This excellent Bryston 4B amplifier has recently been professionally inspected and had a new power cord installed (see pic of receipt). The tech who serviced the amp said, "This is best made amp I have ever seen." What others say about the Bryston 4B. "The Bryston 4B is something of a legend. As our most popular model, it has attained international status as an amplifier suitable for the finest and most sophisticated sound systems." "This power amp is built like a TANK. 55 pounds of quality, 200 watts per channel, power that will drive speakers with demanding loads without breaking a sweat! I can't believe the solid deep bass and the crystal clear highs. The mid-range is smooth and silky without the grain like other amps at this price. Bryston has a 20 year warranty that transfers to the new owner. This one is a keeper. You can't go wrong with anything Bryston!" Description: Solid-state stereo power amplifier.
