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.

Hey Supratek owners -

Quick question - what rectifiers and regulator tubes are you using? Anybody out there rolling these? and, if so, what are your opinions about the best sound?

I'm running a Mazda GZ32 as a rectifier and the standard 6N3C regulator tubes. I've always been curious about whether and how much different it would make to swap these out for, say, a 274B and a pair of 6L6, KT66 or 5881s.

 Not sure how much I can contribute since I own and rolled tubes in a Cabernet not a Cortese.  All tubes make a difference.  My preferred rectifier is a ‘58 RCA 5R4GY brown base ST shape.  Another bargain is a Sylvania 5U4GB USN Tall straight bottle with D Getter.  I preferred both over highly recommended and pricey Philips 5R4GYS and Mullard GZ34.  Your Mazda is most likely going to be hard to beat.  A llot of people rave about the Sophia 274b Aqua II.  It’s more than I want to spend and some have had failure issues. For your regulator tubes I would definitely upgrade from those stock Russian tubes. I like ‘60’s RCA  6L6GB blackplates  and 807’s with adapters.  These were a nice improvement over the stock Russian tubes.

I joined the Supratek owner’s club recently with a new-to-me Chardonnay.  Very happy with it.  It’s been a better than expected improvement to the music over my Schiit Freya+.  What amps are people using with their Supratek?  

@nymarty I’m in tube heaven with my Decware Torii Jr. I finally received in January. It was a 2 year  build wait.  I think it’s 4 year wait now 🤯.  In the interim I bought an LSA  Warp 1 but sold it once my Decware amp arrived.   It’s a fantastic Class D amp at a great price. It did everything well including bass.  Just have to follow my audio component rule “If I buy one I have to sell one”
