@tksteingraber , the shipped rectifier tube with the Cabernet 6SN7 is from JJ Electronic (Slovenia) JJ GZ34 5AR4 is their ID.
Many thanks for the list of choices...looks like the RCA are a good start.
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 tried Ingress rollerblocks under my Grange and heard some nice sonic improvements. From what I understand they are similar to Symposium rollerblocks but at a fraction of the price. I might try them also under the Supra power supply unit. There are few forums mentioning the Ingress products as well. https://audiotwo.com/products/ingress-audio-level-2-stainless-vibration-isolation-system

I don't have a Supratek power amp. If I needed a lot of power and wanted to stay with tubes I'd seek out something along the lines of an @atmasphere or a @donsachs Kootenai. If I didn't need a lot of power because I had highly efficient speakers (ala Klipsch or big Altecs) I'd seek out an Alan Eaton 45 stereo or monoblock setup. |
One other thing that has really improved the sound I'm getting from my Cortese are some Cardas cables. I'm using old, but new-to-me Cardas Neutral Reference wires from DAC to preamp and from preamp to power amps. Also Cardas NR speaker wires. They're, like, 20 years old, but they are a huge upgrade for my system. Previously I just hadn't paid much attention to interconnects or speaker wires. |
