Need advise on HT Pre / Proc

I'm want to integrate my 2ch and HT set up and am looking for solutions for a pre proc.

My 2ch systems consists of a pair of Dunlavy Sc IV A's driven by a Mcintosh MC 352. This is driven by a Metric Halo 2882 used as a DAC fed by either FW or optical out of an Airport express.

I'm looking for a 5.1 pre the has a good 2ch analogue path or a DAC on par with a Benchmark or Lavry da10.

Inputs will be.
PS3
Oppo blueray DVD
Apple TV or other set top server box
2 Ch audio via afore mentioned DAC analogue output (balanced) .
or 2 Ch digital is the pre has a nice DAC.

Looking to spend in the 1K range, not opposed to used.

My TV is 720p/1080I Sony RP LCD and has 1 HDMI input, 1 DVI input, 2 Component.

Some of the pres. I was looking at were.
Yet to be released Emotiva.
A used B&K AV 50
A used Krell HTS.

Open to any and all suggestions.

thanks,

dw
