My HT system in the works.

HT Receiver--------YAMAHA DSP-A1 A/V DOLBY DIG/DTS INTEGRATED ????
CC--------------------PMC DB1M-C
Front L/R------------PMC DB1
Rear------------------PMC DB1
Subwoofer-----------Paradigm Seismic 10
DVD/CD/SACD-----Denon 2200

My family room is 16'x13'x9'h
WAF is in full swing hence the smaller speakers.

My question is on the receiver.
My budget is $800 to $1000us.

I'm looking at the Marantz 7400, Denon 3805, and the Yamaha 2400.
I'm also seriously looking at a YAMAHA DSP-A1 in mint condition that is available to me for about 600us.

Though this is an older unit, I believe the amp section will smoke the above mentioned units in sound quality. I'm I mistaking?

The PMC speakers are higher quality and can really benifit from a better amp section.
Along with Bryston (which I can't afford at this time), engineers most likely used PMC to master the movies we listen to. (http://www.pmcloudspeaker.com/intro.html)

I'm interested in the best sound quality at my given budget.
I plan on staying with 5.1 and am not interested in the latest DSP modes.


Any advice or suggestions would be appreciated.
