I tested the 7125 around Christmas and during my testing the 7125 got super hot when driving my B&W 603's. I really don't know if I got a bad amp but I couldn't touch the top of it and it when into protection mode on the left channel. Now I did talk with Outlaw , tried there sugestions on the power outlet, speaker wire,and a few other sugestions. Well I sent the 7125 back got the 7500 and haven't looked back. The 7500 is the ticket for me. Good luck!!!
