Supratek Owners Thread

Greetings All - 
It appears that the 26-million-plus view, multi-decade "Preamp Deal of the Century" Supratek thread has been removed. I'm not sure why, but suppose there must be a reasonable explanation.
In any case, on that thread I recently asked whether there might be interest in a "Supratek owners thread" and received some interest. 
The purpose of this thread is for Supratek owners to share the details of their system, ask questions, share information about any tube-rolling they have done, and so forth.
I'll kick us off here with a few details about my system -
ancient Linn LP12 with Ittok arm, Dynavector 17D3 cartridge into Cortese LCR phono stage
Power amp is a fully serviced Innersound Electrostatic amplifier
Quad ESL63 speakers (not USA monitors) or JBL 4430 studio monitors
Digital sources are immature and evolving - ancient Fostex CR300 cd player/burner
DacMagic 100 DAC
Nordost Blue Heaven 75ohm interconnect
Due to the fairly long lengths of speaker wire required in the new listening room, speaker wire is Belden 12 gauge wire designed for low-voltage outdoor lighting systems. 
Next steps - dedicated circuit, new power cords, new interconnects, new wires.
Received an email today From Mick saying that my Pinot Phono Stage is done and is being play tested. It will be shipping next week! In the meantime I have been re stocking my Supratek tube rolling stash. Another long week of waiting though for the Pinot.
What tubes have you rolled? What have you found to make the biggest difference? What is your favorite configuration?
In all my emails with Mick he's basically expressed the idea that tube rolling is unnecessary for his preamps.

@markusthenaimnut the only other dac I've tried was a Parasound.It actually didn't sound too bad,but it became congested with complicated music.My Vincent CDP died(which I loved!) so I am going with separates again after a ten year hiatus.The Tubadour(upgraded caps)is a keeper for sure,really euphonic out of the box and becoming more open and organic as it breaks in.Don't want to hijack the thread,sorry audio123!

The 6SN7 tubes I really like are Sofia Electric,lush but detailed.I've heard good things about the Shuguangs but haven't tried them yet.
Greeting to all the Supratek owners...Just a little info...but these new to the market  Shuguang WE6SN7 are SPECIAL! about 200hrs on them and they are a end game for me...will be giving a little more info when i get another 200hrs on them...but so far....LUV THEM!... Micks latest  Chardonnay GEN 3 pre is a beauty to the Ears and Eyes...and without a doubt one if not the BEST audio decisions i ever made....if your on the fence about buying on of Micks masterpieces...well jump off it and BUY'll be glad you waited and got the latest Model (GEN 3)...TRUTH!
