I just purchased M80's after many months of careful auditons and I am very happy with what I have in my home. My current systems has a rotel preamp/processor and a five channel amp for surround sound. I purchased two new two channel rotel D amps and am absolutely convinced that they make a huge difference in sound quality. I am curious if I should be concerned about knowing how much of the current is running to the M80s? Entering into this new world of power, how can I make sure I do not over power the new speakers?
