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.

I ordered the new Supratek Pinot Phono Stage in black on black. I sold my Sutherland 20/20 to make room for it. This will be my second Supratek, the first was the Syrah pre amp. I loved the Syrah but had to sell my gear and downsize around ten years ago. But I still have some of my tube collection and they will work in the Pinot, such as the Sylvania metal base 6SN7A, Western Electric 350B, and Bendix 6106. Its going to be a month long wait though as Mick went on vacation right after I ordered. 
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.
Audio 123, Western Electric never made a 6SN7 tube, nor an equivalent. Shuguang needs to go and do some research.
Marcus, sorry I did not see your question until just now. I haven't received the Pinot yet, Mick is still tinkering on it. But, with the Syrah pre amp I did quite a bit of tube rolling. As far as the rectifier goes I tried the Mullard GZ34 and GZ37, Bendix 6106, RCA 5V4GA, Cossor 53KU. I could not tell a significant difference in swapping regulators. That is until I rolled in a pair or W.E. 350B's as regulators, then the Bendix 6106 was daddy'o! I put all the others away and stayed with the Bendix. On the 6SN7 I tried too many to list. All of the WWII Sylvania's are just great in the Supratek, as well as the 1949-1951's. You cant go wrong with any of them. But, the 6SN7A, 6SN7W, 6SN7 GT metal base version are easily superior to all other Sylvania's. The Ken-Rad black glass are excellent as well, but not as excellent as the Sylvanias. The very best 6SN7 that I used was easily the Tung-Sol black glass with the round or the oval micas. Just completely gorgeous organic sound when paired with the 350B as regulators, and the Bendix rectifier. I was also using Western Electric 417A in the phono section. 
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. 

Never had that problem but Mick does find a solution, he did for me!
Let us know how it turns out.
