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.

@luisma   probably isn't but only 1 maybe 2 of the new Grange pre's with their owners yet.   I believe he only shipped the 1st one within the last month.     There's alot going on in that pre and it takes Mick a long time to complete the build.   Hopefully  an owner will post here with impressions but I'm pretty sure I already know how it'll go,.. lol
I should be getting my Grange Signature by New Year. Mick said it was his favorite circuit design. 

I ordered Gloss black with Chrome. Looking forward to it.
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
