In Issue 188, December 2008, of The Absolute Sound (which subscribers should be receiving soon), RH reviews the Onkyo TX-SR706. He seems favorably impressed with this $899 receiver when hooked up to the Wilson Alexandria X-2s. The Onkyo has Audyssey room correction.
RH says "Audyssey seemed to clean up the problem frequencies while maintaining the fundamental character of the sound in my room".
AHC, a few issues ago, while giving a Golden Ear to two Onkyo receivers, didn't seem happy with Audyssey set up at least.
JV, in an email to me says "ergonomically it is a nightmare (including that vaunted DSP program)"
We'd love to hear the experiences of others who have tried this (whether in an Onkyo, Denon, NAD, Marantz or other product).
