Tube based surround sound amp???

Hello fellow audio nuts!

I am trying to downsize in a fairly drastic way, and my hope is to merge some gear from my two channel set-up with my home theater.

I plan on selling my beloved highly modded Fisher 500c, as well as my Eastern Electric Minimax CDP (both from my 2 channel rig).
What I hope to do is find an integrated amp for an IPod based 2 channel system that I can also use to run a 5.1 home theater set-up.

My speakers are Northcreek Rhythm Revelators- 4 ohm, 90 db efficient.

I would love to find tube amplification again because I'm addicted to it, and it helps tame the slightly tipped up highs of the Northcreeks.

I would love to make the Northcreeks my main speakers, and integrate them into my home theater set-up.

Right now I'm very intrigued with the Peachtree Audio iDecco, because it has a digital direct iPod port and, at least, tube preamp. Not sure about the 30 watts though?

Any thought on the iDecco?

Also, would I need a separate surround processor for home theater? Any cheap recommendations?

I'd like to keep my budget well under $1000. I saw a used iDecco for $575 on Audigon, so I have about $500 for a surround processor if needed.

Thanks for any advice. I am obviously an enthusiast, but not a true audiophile and any advice is much appreciated.
