Modified vintage CJ preamp vs. new one

I have a vintage Conrad-Johnson PV11 preamp which I had modified by the company with Teflon caps.
I like the sound of it.
As a matter of curiosity I’d like opinions as to whether it would be an improvement if I were to replace it with a new CJ model.

There does not seem to be a lot of feedback , or reviews in regard to the ET6 available. I am also curious how the ET6 compares to the ET3 and even other vintage CJ preamps.

For what its worth,  I own the Classic 2SE and after demoing that and a non SE ET3 in a 50k plus system I thought the Classic with Teflon caps  sounded better.

KeEp the upgraded CJ Pre. 
  Use her for many years to come.  Enjoy he music. 
   Ou would make a sidestep and be out of unite a lot of money.

 Save $, new cables. 
 The PV pres’ were great   
 Keep your upgraded preamp!

 Probably not even broken yet, those Teflon caps take hundreds.  Of hours to fully break in.

Hi rvpiano--
Your PV11 only has Teflon caps in the power supply. There is no physical room in the preamp for Teflon caps or Vishay resistors in the audio circuit.  The ET6SE, has better quality RCA jacks, Teflon caps in both the audio circuit and power supply, and Vishay resistors through out will sound cleaner, more dynamic, more detailed, and more neutral. Hence, more musical and maybe even a tad warmer. If your ears want that great of a change then go for it. Would be happy to speak off line.
