Oh, do tell us how much 6.1 or 7.1source material is out there and why he
should unload his 5.1 system. I guess you'll just come back with "gee, fake
6.1 is just the bomb"

Loco, all Dolby Digital will play through the rear CENTER channel so long as
you have EX decoding. All of it. Only DTS won't. So that means MOST material
will play 6.1.
I'm not going to attack you over this, I only learned about it when I upgraded
to a current decoder. The rear center is quite nice. I'm using 3 matched B&W
LM-1s with a secondary Paradigm sub.
Here's a pic of Center rear:
