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.

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.

Placette Active Linestage has 2 outputs. O.K., so it's solid state, but supposedly one of the most neutral preamps available due to its high quality volume control. Also has 30-day in-home trial. I'm considering this preamp for a biamp setup. They also have a passive preamp for less $$.
(See their ads in AS and their web site for info.).
Let me posit a conjecture: I believe that there could be a difference between using an external "Y" adapter vs. going with an internal two-output design in the possibly reduced input impedance seen by the parallel-connected single output in the latter case. In this scenario, hooking up two amps through a "Y" apdapter could increase distortion, reduce headroom, and compromise frequency response with a preamp whose output wasn't designed for it, whereas an appropriately designed dual-output preamp wouldn't suffer in driving two amplifiers. But I don't don't have the expertise to know this for certain; it would be better if someone more knowledgeable than myself could post after me confirming or refuting this.
