I'm going to order a 755/770 and I'm currently borrowing a Proceed 2-channel amp from my friend. If anyone wants to see entirely subjective test results of stereo performance comparison between these two amps, I'd be happy to provide these. Additionally, I ordered a set of CDs with test tones, so I could provide a rudimentary frequency chart comparison of the two amplifiers.

My system is: Pioneer Elite DVD player, used as transport to a Proceed AVP (old version), and Linn 5140 speakers ran large (I have an SVS sub, but prefer to listen to stereo with no sub). There will be no differences in the tests other then amps, and I'll set levels with a Radio Shack tester (and possibly CD or Avia test tones). I guess I could also provide subjective HT tests, but I don't know that I would be able to hear much of a difference.

Yes.
...and thanks for taking the time.

Ok, I'll post in about 3-4 weeks. I have to clear some space off my credit card before ordering, and then set up the two amps. Unfortunately, unless I have another tester, I will not be able to do a "blind" test (where only the tester knows which amp is playing). I may be able to con a friend into helping. We'll see.

I second that. I would definately like to hear your opinions. Compared to my aragon x5, the 770 was sent back.........

Me too! I third it!
