Hi I have had a dem of the Denon 3805 and some B&W 705/HTM7/DS7/ASW700. I have a small 12 x 13 ft room. When playing 2 channel music the amp sounds fairy happy and reaches loud volumes at -25db. Sound quality is smooth and nice Switched to 5 channel, the volume control has to be raised to -5db to acheive realistic volumes and the sound quality drops somewhat. Is the 3805 capable of driving the B&W set ? Would it fair better with the MA Gold 10 / GR Centre / GRFX set up. Is the B&W particularly hard to drive ? Do I need to look at Denon 1SR / Yamaha Z9 quality amps to get reasonable sound from these types of set ups ? Many thanks Tom.
