Loud is pretty subjective to most people, but to me, my system plays very loudly and I certainly don't have a tenth the system that Tharkon has. My setup is a H/K 3480 (120 wpc), with m60ti's. I don't even have a sub and it cleanly plays louder than I can stand in my medium sized living room that's pretty open to other parts of the house. I can't imagine anyone not being impressed with how loud my current system is, let alone m80's with a big honking sub and 200+ watts of power like you're talking about. In fact, the first night that I really cranked it (while the family was out of the house) it was so loud that even with the windows closed, my wife said she heard the stereo playing from inside her car (and she had the radio on and the windows up) when she pulled in the driveway. Hey, I just wanted to make sure the new speakers could handle it! Oh and the sound was amazingly clean to my ears even at that volume.
