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
