Jack,
I can find the VSX-9300TX for sale on the web but not the VSX-D1015TX-k...
and at the Pioneer website they show the VSX-D1015TX-k but not the VSX-9300TX...
Stupid Internet!
Oh well, the VSX-9300TX is the better receiver right? and it is within my price range so I may be getting one of those.
I get some Hi-Fi DIY magazines that have surround speaker kits that look interesting as a speaker upgrade.
