Denon 1 said : Plinius SB301 is in a different league from bryston 4bsst2. I fully agree with him. Long ago, I own a pair of Bryston 7b mono block, it sound harsh and not musical. I sold them and switch to MBL 9006, I own the later for 11 years and still using and enjoy it very much. In my another system, when I listen the Plinius SB301 in my house, I sold my Accuphase A45 and never look back. I use the SB301 almost 4 years till now and still love it very much. It is open in character,very transparent and powerful in bass,very musical. I learn the fact : we cannot simply conclude a Pure Class A amp is better than class AB amp.
