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 just bought a used Chardonnay and got it running after a few hiccups like a stuck input selector and then getting a bit confused on using the correct input. But, all is well and this is one terrific preamp!!
A few things that were noticeable right away: 
1) detail retrieval is excellent 
2) this is the best representation, by far, of individual voices in a chorus 
3) voices and instruments are much more natural 
4) less glare/harshness and I’ll admit to having an asymmetrical room that needs lots of treatments  

The tubes I currently have are 
5U4C rectifier - Russian (green and white box)
6NS7                Tung-Sol 
6N3C                no brand visible

I’m quite open to tube rolling and an upgraded umbilical cord, maybe even a fuse upgrade. A couple of Agon members have been very helpful already and I much appreciate that.
