first, i do not know what the "B&M" IS THAT you are referring to. obviously you haven't heard high-end audio equipment. And, i will stick by my more power the better. but, i do not refer to receivers, as the tuners create quite a bit distortion. i have heard, systems costing in excess of $100,000. i listened to HALCRO AND BAT if you know what that means. i don't want to brag, but i put together a world-class 2-channel analog system after much experimentation and auditioning.
