I currently run the Polk LSi tower speakers with a 7 yr old NAD 320BEE as the sound system for my TV. We are sparse watchers of TV and 5.1 while nice may not be in our future anytime soon. I am very happy with the current combination. However, I am looking to setup the 320 with smaller PSB speakers for the TV (moving to a new place and TV room will be smaller) and getting a NAD 375 for my office with the Polk LSi towers. (Office in home and I can crank it while working) I can't wait to hear the Polks with the 375 but they also have a M2 and frankly after reading a bit about it I am not sure I understand it. The inputs are different.
Any feedback with NAD Polk combo appreciated and also have question regarding the M2 unit by NAD. Will the LSi speakers do the M2 justice? I have heard of people running special cables for the M2. Will I need a large room to play the M2 on my Polk speakers? Other items to consider ref NAD M2?
