Good choices in a used A/V pre-amp?

I'm slowly re-building a home theater. My amplification is about the only thing set -- a B&K TX4430 (200w x 3) for the fronts, and a B&K EX442 (200w x 2) for the rears.

Now I need a DTS pre-amp, and I don't feel any need for 7.1 (or should I?). I'd like to try to stay around $500 or under, hence going used. I haven't made any firm decisions in the speakers I'll be driving, a project for another day. This is a home theater system only -- no music listening. I'm re-building because I'd broken up my rig long ago for a dedicated 2-channel high end system for another room.

Is my $500 price point enough for a used a/v pre-amp? What are some key features I should look for? Brands and models?

Thanks!

Kitchener,

In responsze to your question on 7.1, I highly recommend auditioning a properly set up 7.1 system before finalizing any decisions.

In my own case, when I expanded from 5.1 to 7.1 I found a significant improvement in surround envelopment, so much so that I'll never be satisfied with 5.1 again.

The Lexicons recommended above will give you the ability to generate 7.1 outputs from any source. An alternative that is now coming into more widespread use is DPLIIx.

Thanks

Good stuff. Gives me a short list to work with. The 7.1 vs 5.1 argument is worth further consideration, too.

How picky do I need to be for sub-woofers for a relatively small room (~11' x 20' with the listening position forced to be in the long part of the rectangular room, ~10' from the front speakers)? Was thinking a Sunfire Jr or an HSU. Again, this is not my music-listening system, so I don't need to find something that serves both needs. What would you all recommend I put on the short list for a subwoofer?

Another vote for the Lexicon DC-1. With Logic 7 processing, it was designed for 7.1. DTS capable as well as Dolby Digital. One of the easiest processors to program on top of that. I still know of one that was installed in a million dollar theater(I'm not joking) in Mendocino that is only now slated for upgrade.

I neglected to mention that I obtained my DC-1 v2.1(DTS,DD,THX,Logic7) for only $500. This is an absolute bargain by any standard of measurement.

Porchecab,
I actually have 3 Angstroms--2 w/dts and the 205 and one just pro logic. Moffit was way ahead of his time. Too bad MML had to close; who knows what he would have come up with!
I use on of the Angstroms in my main system sharing time with the Lexicon MC-12B. The other is for the second system. I'll save the third one for parts, etc. I do not use the 205 at the moment; it's kind of a pain in the butt to set up and use. I just use the Angstrom for dts and matrix (mostly for sacd 2 channel-the lexicon won't process the 2 channel in surround). IMO this pre-pro performs with the best of them at about any price. By the way, there's a 200/205 combo for sale on this site for $895; alittle pricey but still worth it. When I see a good deal on the 100, I'll get it for DD.
