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.

  • Perfectly said. My interaction with Mick was like this:
  • Initial Contact of expression of interest in LEARNING his views on Preamp selection Vs my Amps Vs my speakers.
  • The Sound i would enjoy at 70 dB SPL in the late quite hours of the evening + a Humble description of the type of Music i typically listen to. In this case it is Jazz.
  • The outcome product is very successful for the Ears & Eyes for both of my wife - i allways involve her in my passion - and myself.
i must also to acknowledge you all here. You have educated me. You have opened my eyes towards a Huge Joy. And this to happen in this now famous 2020.

Here's what I think Joseph means regarding the "handpicked tubes" - the Supratek sounds incredible with the stock tubes. And Mick has carefully auditioned all the usual suspects to identify high-value, solid-performing, reliable tubes that he can purchase in quantity. That's the way I've felt about my Cortese, though I have done some tube rolling.

I was very intrigued to read the comments on tube-rolling earlier in this thread and, based on that input I'll probably track down some Melz 1578s and a pair of the Shuguang WE6SN7 plus tubes, just for fun. At present I'm listening to a gorgeous pair of CBS 5962s. They sound wonderful.

All the best,
Markus
Markus -- Thanks. Never heard of the CBS 5962. At least at Upscale Audio they don’t come cheap, but I just noticed what look like a good matched pair on eBay for a reasonable price. I've been using the Shuguang replica and it's a nice tube. There are some other possibly good choices at Grant Fidelity.
The CBS/Hytron 5692 is a pretty good reasonably neutral tube. I roll a pair through the Chardonnay periodically.
A 6SN7 search today turned up a few resources I had forgotten or hadn't come across before (links can't be posted on Agon). Some good info.

What these lists don't include are the more recent Chinese tubes.
