Which preamp to go with pass labs x150.8

Hi all, 

I am getting Pass Labs X150.8. I am considering following preamps: 

Simaudio Moon P740 

Ayre KX-5 Twenty 

Audio Research LS28SE

Pass Labs X12

Which preamp would sound the best with the amp? 

Thanks for your input. 


Aric Audio! His preamps are a sublime pairing with SS gear. I have the original Motherlode first paired with Pass monos and now with a Coda Model 16 and I cannot speak enough about his tube knowledge, craftsmanship and customer service. 

+1 for Aric Audio. I'm using his Super 6SN7 (with upgraded PS and volume control) with my Pass X30.8. A great combo and big step up from my previous preamp, CJ CT-5. Aric has great customer service and can taylor his preamp to your needs.


Good luck

Okay, my .02.

While my equipment is different it might be revelant, I currently have a Pass 260.8 and run it wilth an ARC 5se. Before that I also used a ARC 28se (which is currently running with a ML 23.5)

Have always liked the sq of the mix of tubes and ss and had tried a number of tube and ss pre with these amps until I got to my current rigs. Not even considering a upgrade of either, but you never know when the bug will bite...
