MikeM:

I went through a similar analysis when my 975 gave up the ghost early last year when Outlaw sold the Marantz AV7705. IMO, the Marantz processor line is totally superior to Outlaw's when it comes to features if not functionality (e.g. Atmos, HEOS, Audyssey, MM Phono Input etc). The 976's is reportedly quieter but I have 69 year old ears. I ended up purchasing the 976 as it was the most cost effective solution to my immediate needs.

Regarding waiting for a new ProPro from Outlaw, you might wait far longer than the decade it took Odysseus to return from Troy. Whether is fair or not, its been over a decade since Outlaw canceled its 997 replacement for the 990.
