hello to all.... recently, I have changed the stereo to the multichannel systen sound . Before, I had some SF guarneri with a subwoofer SF gravis. When I bought the AVR192R, I also buy B&W nautilus 802, Htm1 nautilus, 805 nautilus and a subwoofer ASW850.. After, I listen for long time, my new system, every time I liked less and when I listened the system in stereo, it hated it. (how is it possible? with better speakers and better processor.???.. the speakers were "running in"). I returned to the dealer and he tells me that "my pleasure " in sound is that of Sonus Faber that there is not any problem between TMA and B&W. From my point of view with SF, the system sounds excellent, clear and soft in stereo, wide sound image, while with B&W, I put on of bad genius... question of synergy or of sound pleasure?
