I should have given a bit more information on my above post. I am interested in istening to the M60's and or M80's because I am seriously considering purchasing a pair. We have a very large 'main floor' with cathedral ceilings (20' x 40' and vaulted ceiling of 20' in about 1/4 of the room). the speakers are for a 2 channel application and dedicated to music listening. I am in the process of building the system and will likely purchase the NAD C375 BEEE intigrated amp.
It's likely I will need to add a sub due to the size of the room which I will do down the road.
It would be great if I could hear the M60's and M'80's prior to purchase.
