I agree with Stewie in that I've been surprised by the 7700 and just how good it is. I have not heard the 7125.

My 7700 even holds it own against a stack of high end British 8000P Audiolab mono blocks.

I'm genuinely surprised at just how good it is.

As you'll see from my profile, I also have a serious active Naim setup. The Outlaw cannot match this, but the 2 channels of Naim Naim amplification run at $7500 per channel on the back of a $10k pre amp. This compares with $275 per channel from Outlaw. The intewresting thing thouigh is that the Outlaw is not as good as the Naim but the difference is not that great, i'm sad to say!

Good luck
Rob
