It seems if you want a multi-channel amp from Outlaw today, you've got 2 choices, the 7125 (7 x 125w) and the 770 (7 x 200w). Curiously, the 755 is still listed in the Products section of the website, but says "discontinued." None of those choices have balanced inputs.

Is there some reason why you want balanced inputs? Is your environment particularly "noisy" with EMI/RFI?

Cheers,
