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 brought a 2nd hand Cabernet DHT a few months ago ... what an amazing preamp, I also have a range of valve amps to compare, Ayon Auris, AR LS15 and a 2nd system using McIntosh C22/MC75's, the DHT just nails it ..

I have a range of valve and SS power amps and after much trialing settled on it fronting a Accuphase A70 driving a pair of Dynaudio Platinum C2's.  My main sources is DAC Accuphase DC37, but also a Marantz SACD/CD player.  I am yet to be happy with the quality of sound from my phono, have a Linn Lp12 and Rega RP8 so this is a project for the future to sort them out ...

The awesome guy who sold me the Supratek also supplied me a great set of valves which so far sound the best against what i have rolled.  He did a lot of work tube rolling and really knows his valves.

Output tubes - Emmission Lab 45 Mesh Plates (these are just amazing) and a set of PSvane 300B

Input Stage Inner - Sylvania Metal base 6sn7 - unfortunately 1 went microphonic so I have some vintage Sylvania's in now .. though absolutely luv' the metal base sound, lush and open but $$$

Input Stage Outer - Sylvania Vintage (1950s) 6sN7 (nice clean open sound)

Power Regulator Pair - Valvo EL34 1960

Rectifier - GEC U52, again an incredible valve


I also purchased a set of vintage Mullard GZ37 rectifiers to try, but there is a audio difference with the GEC U52.

I am tube rolling 6SN7's, have and tried EH, Shuguang - Grant Fidelity, RCA, and the Sylvannia sound best for my ears.  I have just acquired some Ken Rad black and clear which will ship today.

I tried the PSvane 300B, but much prefer the EML 45M.  Also picking up today a pair of RCA JAN 2A3 and just acquired a quad of RCA Cunningham Radiotron 45 valves.  See where I end up ...

there is some warmth, I also have some NOS RCA's, the Sylvania ( GT - 1951 and VT-231  1944) sounded nicer and smoother. 

Been running the RCA JAN 2A3's this afternoon ... very nice, more detail and separation than the EML 45M's, beautiful vocals .. bass is a little better on the EML 45M's, and they seem a little more tolerant of poor recordings and better for driving music eg., Funk ..  Overall very happy, will leave them in for a while.

I acquired a 2nd hand Cabernet DHT middle of last year, I am extremely happy with the unit, it replaced my Ayon Auris which is also a nice pre-amp.  It came with Emmission Lab 45M in the output which are good but i have been tube rolling and now run mainly vintage 2A3 valves.  There wasn't a remote with mine and the seller said can get a 3rd party remote that will work.  Does anyone know what remote/s work with the Supratek ?
