I just got my 7100 bstock last week. First off built like a tank, I couldn't believe this is the lightest Outlaw amp. Others have mentioned the improved sound quality at high volume, but I hear a great difference in the sound quality at low volume. The low volume quality of my system has bugged me since moving from two channel receivers to home theater receivers, no longer. For home theater this amp really excels, the rear surround channels are crystal clear (I have 5.1 setup) and center channel dialog is equally clear. I was worried that 100 watts would be enough, but the difference between the 100 watts in the 7100 and the 75 watts in my receiver is like night and day, more than enough power for my fairly efficient speakers.
Any complaints, only that it seems to run a little hot, but I haven't had any problems with overheating. Thank you Outlaw for a great amp, I can't wait to upgrade to a pre/pro.
