Hey, fresno, thanks for the info. Yeah, the Audyssey algorithms seem pretty cool.
There's almost always pros and cons to each unit. The Onkyo 506 (I'm not sure about the 576) can't process audio from HDMI, nor does it have a switched outlet, a 12V trigger, or THX surround modes. The MCACC auto set-up feature on my Pioneer 1015 impressed me, and the newer models have an updated version of that algorithm. So, while the Audyssey algorithms do intrigue me, I'm not going to rule out a new Pioneer because they don't have them.
However, now that my 1015 is working again, I'm not in the market for any of them.
