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.

@rh67 looking forward to your impressions of the XA25 with the Chardonnay preamp! Please keep us posted.

What preamp are you using now?
Good choice and definitely worth the wait, although I’m surprised about the time, as not long ago he was advertising the Chardonnay here on Agon and delivery looked almost immediate.

An idea while waiting is to time to acquaint yourself with the tube 6SN7 and recti tube market, if you aren’t already (the rear tubes in the preamp section are probably best left alone). In addition to reading this thread, good sources I’ve found are the following:

head-fi:
- the reference 6SN7 thread
- dubstep girl’s massive 5ar4 5r4 5u4g rectifier review (p.1 & p.118 redo)

What’s Best Audio Forums:
- Lampizator Valve Tube Rolling thread
- Psvane Acme Series (new flagship series)
- LampizatOr Golden Atlantic + TRP

TNT Audio:
- shuguang treasures cv181 thread (pt 1 and pt 2 - two threads I think)
- shuguang globe 6sn7-e thread

YouTube:
- 6SN7 NOS tubes video

Grant Fidelity: go to GF site and click on Tubes for info and sales (located in Alberta Canada I think). Top notch & prices & service

Some of these are obviously indirect and just a matter of reading through and spotting ideas that you likely won't come across elsewhere, and also asking questions privately. I wish I had read these earlier, as it would have saved me a lot of time and money with both my Lampi TRP and the Supratek. Also feel free to message me if you have any questions (and for ideas from some private messages I’ve received). Good luck,

Gene

P.S. As for isolation, the AV Roomservice EVPs are about the best truly effective low cost deal around (I have four MDR’s under the pre and four HDR’s under the pre PSU -- under speakers too).
I`m using a LTA pre now. For me the LTA`s are a little on the cool side. And thanks everyone for the 6SN7 info.
highstream. Mick said he has been very busy during this pandemic.

The reason i decided on Supratek was not only the reviews but reading thru his blogs it became apparent that Mick and myself have the same beliefs in sound and what sounds good and what does not and the whys. And his thoughts and experience on class D amps mirrored mine to a tee.
