Guys, I need advice on the performance of Sony power amps, specifically ES models like the T-AN 55ES. I can't find detailed reviews on this model. I know they are 120watts/ch. at 8ohms and bridgeable to 300watts mono at 8 ohms . They were made around the early 90's and already uses toroidal transformer.
Any comments, specially to those who already experienced using this or similar models, is highly appreciated. Tnx
