Melos MA333 Reference upgrade worthwhile from MAR

Has anyone had any experience with Melos Audio Restorations MA-333 preamp Reference upgrade? MAR has upgraded my MA-333 with Solen caps and resitors about a year ago which made an improvement in extention.

The reference upgrade removes all mosfets in the circuit to make it a total tube preamp amoung many other changes to the 6922 tube circuitry.
Thanks for your time.

In addition, I am looking for power cord recommendations for the Melos MA333, Plinius SA-100 and Sony SCD777ES.
Thanks for your time.

i can't say whether or not this upgrade is worthwhile, but at some point, it is something i will have done to my music-director. what i'd *really* like is for m.a.r. to come out w/a more reliable version of the photentiometer - an amazingly transparent volume pot, much better than the alps that replaced it for reliability reasons.

re: power cords, i use the stock cord, but the pre is hooked up to a vans evers unlimiter. as far as power cords go, i am considering making my own w/a recipe from john risch's diy cables website. i am not ready to drop big money on powercords...

I have the Maestro and want to upgrade my alps volume to the photentiometer also. I upgraded the output caps and the sound is better.
