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.

Hello there.
I believe that I am the first owner of the new Grange LCR phono and DHT line stage preamp. I received it on Oct 12 / 21, after six months waiting for it as a reward. I have been playing it few hours every nights since I received it, no noise, no hiss, no hum. I am extremely pleased with the sound quality from this preamp phono and line stage, the sound of this preamp is so liquid and natural that just can not be described.
Which flavor do you have? DHT dual active? You using mainly a TT with it or digital too?
I bought a Grange DHT line stage built into a Cabernet chassis (basically the Grange without a Phono) in September '21. It has the circuit, transformers and capacitors same as Grange. Very happy with the performance. My previous pre was a MINGDA MC300-PRE
I am bi amp my Grange preamp, 6SN7 tubes drive my woofers, 300B drive the midranges and tweeters. I play both the vinyl and digital, the line stage is as good as the phono.

I ordered a Cabernet 6SN7 a couple of weeks ago. Expecting a three-month wait. Came here to learn more about this preamp. Looking forward to receiving it.
