Tube pre amp with 2 outputs for Biamping


Im looking for some brand names of tube preamps that have 2 outputs so i can biamp my speakers. I do Not want to use a Y adapter. I want two seperate outputs, one for each amp.
Looking for something in a resonable price range, would also consider solid state but tube would be the first choice.

My Airtight ATC1 has two sets of outputs. If you can find one used they're usually under $2k and they sound great.
What's the difference whether the Y connector is on the inside or the outside of the preamp?
Rwwear--The difference "on the inside" would be --it would have the same wire--inside-- as the rest of the wireing--With an outside Y ;we are talking one brand of cable;another brand of Y .Seldom a great thing(understated)
Audio Research Reference 1 has two outputs and I would think that the reference 2 also does.
