Hey waytoomuchstuff,
Thanks for the post. I'm actually very happy with the B&W's and they may have already been modified. I bought them used.
I brought them to a hi fi shop years ago and the salesperson was slightly amazed, saying they sounded a lot better than he expected.
As for the Denon,
I am sort of attached to them as they were a major upgrade from a Sansui receiver I had in the past, but I"m willing to upgrade now.
I definitely would like to hear these speakers with more power. As I mentioned I'd also like to have a streaming option and a better pre amp.
Thanks again.
