Best 6NS7 Preamp for a Pass Labs XA25 amp

I'm finding this to be a very interesting thread; thanks to you all for the helpful posts. I too have a Pass amp, and X150 in my case, and am considering a new tube line stage preamp. I'm now using an early Conrad Johnson preamp, a PV4, and very much appreciate it's sound characteristics, but would like to have xlr connection options and a remote would be pretty nice, too.
The OP mentioned something like "...no Schitt kit", and I'm curious as to why so? I have not heard one, but from specs, the few but positive reviews available, and very reasonable price, I agree with wolf_garcia that it is an attractive option. So, I'd be interested to hear any specifics as to why the other options mentioned above, especially those say under $2k, would be preferable.
Thanks.
p.s. rest of my system includes a Pass Labs Aleph Ono phono stage, Thorens TD160 w/Soundsmith Boheme, Cambridge CD transport, Schiit Bifrost multibit DAC, Vandersteen 2Ce Sigs.

I also have the Aric Audio Motherload preamp with phono stage and Dueland caps. I have been very happy with it.

+1 for Aric Audio.  I have the xa25 with an Aric Audio Unlimited preamp.

Atma-sphere MP1. Any version. Balanced or rca option. Both excellent.

Linear Tube Audio manufacture 3 magnificent preamps that can use 6N7. They are delivered with 12N7's but by moving a jumper on the pcb you can change the heater powersupply to 6 volt and then use the mores expensive but cool sounding 6N7 tubes. The MZ2 with our without your remote should be within your budget? www.lineartubeaudio.com
