Joe's comment to me was if you are running seperates, there is no issue with the M80's. I have had the M80's now for a week and the wife left for a few days, so I have had a chance to open them up. No problems yet and all sounds great!!!
I like the 976, It's a 60 watt amp X 6 ch. but you can bridge the 6 ch. into 3 and deliver 150 watts/ch. Thats what I have done for L/C/R. I have a couple of older Rotel amps bridged at 150 watts for the rears.
These toroidal power supplies Rotel uses really help to increase amplifier stability. Not to mention I love the British sound they produce.
