Beautiful Colored Tube Preamp ($10k budget) to Pair w/ Very Accurate Monitors (PSI A25M)

apparently EAR 912 is a good option 

came up in another thread 

Linear Tube Audio  they make a great preamp get it with the max Lundahl transformer ,order with the 6SN7 tubes , and it also has I believe 12at7 tubes or similar 9 pin tubes ,it was originally designed by tube guru David Burning 

then improved upon again ,it has several stages of regulation ,clarity best CMR capacitors you can dictate the sound with these tube types and at around $6k retail 

will compete with anything in the $10 k range check itout , Mike at Audio Archon 

will give you a fair price and check out all the excellent reviews ,use a good quality power cord and high quality tubes , vintage tube service, or Brent Jesse recording 

for true NOS  tested matched tubes.

My experience with PSI active speakers are they tend to be very “forward” or “energized “ so please consider a preamp with input gain control

Take a look at the Supratek line of preamps. Unique designs,  6SN7 and/or DHT. Adjustable gain. Lifetime warranty. I have the 6SN7 /  DHT Cabernet. Great flexibility to tune the sound to your preference.
