BruceH,
I've owned a lot of exotic gear over the years. IMO, I feel that the Outlaw gear is the steal of the century backed up with the best customer service I've seen

.
The 770 has 7 seperate amps however they share the same monster power source. This amp is no doubt a tank

.I run mine on it's own 20 amp isolated ground circuit for good measure. BTW, I also ran 4 Magnepan MMG's off my Outlaw with no problems, however I'm now running the Axiom M80's, vp150 and qs4's. The mmg's are in my office

.
I could go on and on but I'll spare everyone the sos. The bottom line is that this amp is awesome and worth trying.It's really hard to say why the guy had problems and we can only guess at this point....Good Luck! I hope this helps.
Tom
