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.

Have had my Supratek Gen 3 Chardonnay in the system for about two weeks. Went with some Psvane 6SN7 TII tubes. Last night things blossomed. Full, rich with amazing detail. Seems there's somewhat of a cult regarding these. Well, sign me up. 
Could have taken a more expensive path, almost did for sure. I just don't know how anything could sound any better. 

Guys - couple questions about the Chinese tubes.I see Grant Fidelity is offering (at a very high price) the Psvane CV-181 TII tubes. Also, for a much lower price, what they are calling the WE6SN7s.
On ebay I see the CV-181 tubes & various versions of the WE6SN7 tubes. Some look quite different from the ones offered by GF, but at lower prices.Also, GF wants $$ to offer warranty.So, which way to go? CV-181TII or WE6SN7? Through GF or one of the ebay sellers? Which of the ebay sellers have you used that is trustworthy?
Dentdog, where did you pick up your Psvane tubes? GF? or on ebay?
I went to Grant, but saw them yesterday on Amazon for considerably less. Ouch.
Don't know though if Amazon has the "special low noise" tubes culled out. Mick mentioned that the Psvane Tlls were the best. I have four different NOS 6SN7 pair but don't think they compare to be honest.
