I've got a pair of Bowers & Wilkins MM1's on my Apple iMac. Far superior to the stock speakers on the Mac. At maximum volume the B & W's seems to lack that last 'push over the cliff' in volume. I can use Airplay to send music from iTunes to my Yamaha RX-A1020 located across the room behind me. (My studio is 505 square feet). But that way I'm hearing music from behind and ass-backwards, not as if I'm sitting in a concert hall. If I understand correctly a Yamaha A-S801 amp will provide better sound at my office computer. Is there a smaller footprint option? The computer desk is 35 x 71 inches.
