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.

Hi audio123,
What other 6SN7s did you try? Those WE6SN7s look very cool.

audio 123,
Don Sachs also raved about the Shuguang Black Treasure CV181z. He prefers them over all of the NOS treasures of which his favorite is National Union black glass. The N.U. black glass doesn't even make it to my top 5, so that just tells me its all individual preferences. I have a friend who owns a Sachs pre amp, I loaned him a pair of Ken Rad black glass to try. He flipped over them, said they are easily better than the Black Treasure tubes contrary to Dons opinion. 


But, you do have me curious about the Shuguang WE6SN7 (a copy of a tube that never existed). But a 200 hour burn in? No reflection on you, but that's beyond ridiculous. That would take me 8 months of listening to achieve, I would probably toss them long before that. I would love to hear what you are so happy about but that's too much time waisted on something to "break in". 

Still waiting for my Pinot to arrive. Two weeks in transit is getting painful.
