Hi, We've recently moved and, after a period of redecorating, I'm in the process of upgrading from a Yamaha YSP-1000 soundbar to a seperates 5.1 system. Audio-wise, the only carry-over item is a B&W ASW300 subwoofer, which will be mated to 5 new satellites and a new receiver. As a B&W fan, and for aesthetic reasons, I'm decided on 5 x white B&W M-1s. Noting that the sensitivity rating is a fairly low 85db, I'm assuming that amplificiation of at least 140W per channel will make them sing? Top of the shortlist at present is the Yamaha RX-V767. Sensible choice? Advice much appreciated. LH
