I'm fixin' to buy an Onkyo amp from 2x6 at a very reasonable price, but I just happened upon this nice looking possibility:

It has twice as much power and has more name brand cache (I don't really care about that, though). On the other hand, it will likely end up being 2.5-3x the price of the Onkyo and I have no idea whether it actually works or not.
I'm pretty happy with the Onk (other than its tendency to fall asleep at low levels with quiet music).
Your opinions would be very welcome.
Thanks.
