2 Channel pre-amp...where to start...

I have a dedicated HT/2 channel listening room. I know, it's not the best of both worlds but the room was designed for this purpose with complete acoustical wall and ceiling treatment (Owens Corning).

As I selected equipment, whenever a trade-off was involved I favored 2-ch stereo. That's how I ended up with 2 Aloia pwr amps vertically bi-amp (quite nice). The front end for the past couple of years is a Theta Casanova. HT is great and the audio is pretty good as well.

Now thinking of adding a 2 channel pre amp but because of the configuration I need one with a unity gain input (HT pass through) and remote control. The ones I know of are C-J and McCormack. I'm sure there are others. Aloia pre-amp doesn't have the pass through or would probably be an obvious choice. Since I will be looking in the pre-owned market I will have to read reviews, get some input and take a chance without auditioning. I don't like using (abusing) the local dealers and then purchasing elsewhere.

What other options to consider? Where to start? Thanks.
