I am surprised at the Bryston's lack of bass. I do not use them but it is suppose to be their best future. Have you tried different speaker cables? These can make huge difference if the ones you have don't match the characteristics of the amp and speakers. Otherwise I like the Blue Circle, I am in the process of becoming a dealer for them. Also had good results with Musical Fidelity. There is a TriVista 300 available for $2200 now. That is a real buy for a top quality amp. It would be hard to better its bass without spending 4 or 5 times the money.
