Amp(s) to go with Joseph Audio Pearls

I need feedback on some new Amp(s) to go with my Joseph Audio Pearls. I have a Backert Labs Pre Amp (tube) and a DCS Bartok DAC. Budget is $10,000 to $15,000. Tube or SS is fine. Monos or Stereo is fine. Used or New is fine. 

Thank you in advance for your thoughts and ideas!

Great speakers.  At this level it’s almost all about personal tastes/preferences, so you should really share what sound characteristics are most important to you and what you’re looking for out of the amp and you’ll get much better recommendations here. Not knowing any of this critical info I can’t recommend anything at this point.
Thank you. I listen to mostly classic rock and jazz. I like to be able to turn up the volume and have it hold clarity. mid range and upper are more important than bass although these speaker deliver bass no problem.
