Stereo pre-amps with dual outs for bi-amping and a subwoofer line out

Thanks all for the comments and suggestions. I'm currently running a split signal with Audioquest, just looking for something a little more elegant and I suspected I wasn't looking in the right price point.

Not quite ready to put $3 to $5k down on DEQX, Anthem or Parasound pre, but I'll certainly keep my eyes peeled.

I find it interesting that in a world full of bi-amp + speakers, most stereo preamps leave the solution out of their equipment. But Al seems to have hit the answer on the head. And stereo preamps are dinosaurs nowadays despite being some of the most satisfying/frustration-free listening experiences. 

I see that zero tube preamps are represented here!

Also, I was honestly surprised to see Anthem on the list, I thought they went out of business, guess they just went out of the tube business. Good for them, glad they are still here. The business sure has had to change. Used to be 4 hifi shops in my town, all carrying different brands. Now I've got to travel 120 miles round trip to reach 4 dealers.

My tubed Schiit Freya has 2 single ended and one balanced out. The 2 single ended outs go to my main tube amp, and a generally not in use SS amp for "remote" speakers. No impedance issues noted, and turning the "remote" amp on has no audible effect on the main amp whatsoever. 

Rogue Audio has those features!

BAT pre amps have two balanced outputs 

Yes ...however, better sound can be had using only one pair of preamp out connections.   Listen carefully and  hear a smaller soundstage and less dynamic contrast.  Also using 1 amp of a higher quality  is better than bi-amping otherwise.
