I just purchased a pair of Wharfedale Diamond 9.1's and would like to match it up with a nice integrated amp.
I live in the middle of nowhere and can't get to a place to hear these two amps, but I have read plenty of great reviews for both (I guess I should say I am making the assumption the 640Av2 is comparable to the 540Av2). Unfortunately, I am going to have to make a "deaf" purchase. So...
I would appreciate any thoughts, experiences, and suggestions in making a choice!
