gonk,

I think you may have misread... FYI, this is the spec of ONE of my 6 (I had said 5... I miscounted) monos that I thought I might need to replace due to insufficient power handling of my apt.

Output Power..........................300W (8W), 600W (4W)
Class-A Power........................100W (8W)
Frequency Response..............5Hz - 40kHz (+/- 1dB)
Input Sensitivity......................1 V
THD..........................................≤ 0.01%
S/N Ratio.................................97 dB
Input Impedance.....................47kΩ
Dimension (WHD)...................17" x 7" x 21"
Weight....................................80 lbs

Each of the 6 has a 1500W torroidal transformer. So, essentially, I think I have the equivalent of ~6 770s...

Now, I don't think I can run them on a single 15A circuit. Can I (if so, then I guess I won't need to buy the 770)...
