a good pre amp with remote usd6000 or less used


any good suggestion for a pre amp, SS or Tube..etc..does not matter , but with a remote control, I have 4 sets of AMP
Pass labs XA160, Krell 450MCX, Cello Performance II, Classic 30
ideally this Pre Amp will have XLR, as my active crossover are XLR only

mainly i listen to my B&W Matrix 800
mgmmgm
wondering...does the VK52 wroth the extra .as i can afford upto a used unit of VK52SE
Do BAT pre-amps get really hot?
I've heard some nice systems at the NY shows over the years using BAT preamps (not a controlled experiment of course) but they sure weren't doing anything wrong.
I just don't want something as hot as a power amp.
Normal preamp heat is fine (like 12ax7/6ns7 heat, which I am used to).
Thanks.
