Only regret is not getting them from the getgo. Not sure what you mean am i running them at 8 ohm. I use a denon 3311 with a emotiva xpa 3. The M80's are rated 4 ohm nominal but really have only a small 4 ohm dip. The impedence of a speaker is constantly changing and the M80's present no real problem for a quality amp even if is only rated at 8 ohm's. You have a small room and i seriously doubt you will have trouble driving the 80's to deafening levels. The emotiva came on sale and i just couldnt resist picking one up. I am very impulsive .)
