Hi I had your phone stage about 6-7 years ago and upgraded. The Superpak is a big deal. The tonality and everything you like about your P10SE stays, however everything is presented with ease and flow that your current phono stage just can't do. Background is a little quieter, allow more info (details, soundstage cues, etc) emerge better also.
It's definately a worthwhile upgrade given your cartridge (not sure what a classic TT is? VPI?). Also if you're not running a balanced tonearm cable, this should come before the superpak upgrade. (and a balanced cable to your ref 3)
The big caps in the BAT VKP10 SE SuperPak take a while to fully break in, but you notice the improvement immediately, just get's better over a month or two of playing time...
I do believe if you search, I posted some other comments here soon after I did the upgrade...good luck, post back if you do this and what your thoughts are...
