I have a pair of B&W 802D driven by a pair of MC501 monos. Recently I got an integrated 211 tube SET amp which only generates about 12w class A power per chanel. I hooked it up to the 802D, and it drives the speaker pretty well with such little power. The recommended amp power for 802D is 50-500w as per B&W. Does anyone know whether the little power from my 211 tube SET amp could potentially damage the speakers? Asking this due to a friend told me so. Please comment with your opinion. Thanks!
