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.

It is the same as the gain bypassed on the DHT stage, I measured it yesterday. IOW max gain is the same on each stage
Gain is a tough spec to gather on Mick’s preamps.

I found this review of the Supratek Sauvignon preamp. Overall gain measured 22.67 dB.

That’s in line with a figure Mick provided to me in an email exchange, but I haven’t been able to find the email to verify.
Are there any Supratek Cabernet owners out there who might have had the chance to hear a Shindo or Allnic or BorderPatrol preamplifier? Per @luisma31 , I am not trying to (or unintentionally) knock any brand down. I'm sure these preamps together with the Supratek are all wonderful preamps. But they likely have different sonic flavors that appeal to different people, and so was hoping to get a feel for the different flavors to help me decide. If you have experience with any of these other preamps and would be happy to share your impressions, i'd love to hear them. If you prefer, you can private message me too. Thank you.
