Tube preamp for pass labs ?


I recently bought a brand new Pass Labs x250.8. It seems to be finally broke in after about 800 hours. I’m using a good preamp, the BAT VK-33se. I’m curious what other tube preamps others are using with this amp? 
one thing I did was bought inexpensive Wireworld stratus power cables on Sale for $116 shipped brand new for amp, preamp, dac, and server. They seem to have helped settle my system down quite a bit. I really like these inexpensive cords. 
but, again what tube preamps are you owners of the 250.8 using?

TIA for any info given.

The motherlode XL and Custom 300B Pset

My plan is to have the motherland go to both the 300B and my Luxman M10X.

At least until I decide the M10X is not needed.😁

@maxdukecapone Wow, great products. I am using the Super line stage with an earlier version of the Transcend amplifier. Will likely have the Transcend upgraded to the latest version.

What speakers are you using?

Don’t have experience with Pass but have been very happy with Cary SLP05.  BAT and AR are also great.  I don’t think you can wrong with any of these.  I went with Cary because of 6N’s and tube regulated power supply.
