Preamps with Dual Main Out?


Greetings,
I am setting up a twin pair of Eminent Technology LFT-8a's (that's four speakers) as my main two channel speaker system.
I would like to run both of these pairs of speakers in passive biamped configuration, which necessitates my splitting the signal from the cd and either obtaining a second Audio Research LS-9 preamp to match mine, or a different (and hopefully comparable sonically) preamp with dual sets of main outputs rca.
I had a Meridian 501 at one time which did have the twin outputs, but frankly I will not step back down to that level again to obtain my objective (I feel that the AR is superior).
Any AR-like quality preamps with dual single ended outs? My budget is approx. $1,000 and I prefer to purchase used/audiogon.
Appreciate the suggestions.

The Audio Research and Classe outputs are not independently switched if that matters to you. In your case, I guess it wouldn't.
ARC LS2BMKII has dual balanced main out, one single ended main out and one tape loop single ended out. I have one in your price range if interested. See www.arcdb.ws/LS2/ARC_LS2BRMKII_Back.JPG
