Phono preamp Pass Labs XP-17 or XP-27

I used to own the XP-25 phono and listened to the XP-15 quite a bit before I bought the XP-25.
  The XP-25 was quite a bit better than the 15. almost every aspect of the music was better, especially the flow of the music and dynamics, both macro and micro.
 
   I would anticipate the XP27 has similar performance increases over the Xp17.

 What table and cartridge are you usiing?

Maybe there will be good deals on the 25 now that it’s been superseded by the 27. That’s how I would shop.

I am using a Townshend Rock 7 with an Ortofon A90 cartridge with Harbeth 40.2 speakers
