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
Why not simply use a Y-splitter from the output of the preamp to create the four outputs for the amplifiers? As long as the preamplifier can drive the load (the input impedance of the amplifiers will drop by half) it should present no problem. Give it a try before throwing in the towel on your current preamp. Most preamplifiers with multiple sets of outputs simply use a parallel circuit (electically equivalent to the Y-splitter) and provide no additional buffering circuitry anyway. Good luck!
