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.

@jslateiv Do you know what could be causing audible noise coming through the left speaker when adjusting volume?  The noise stops as soon as I stop turning the volume knob —which I usually adjust via remote.  Thanks!

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?  

@tksteingraber Nice Decware!  My speakers (Devore Fidelity Nines) can run on 20 watts but they seem to come alive with more power.  I'm using the Chardonnay now with 3 different amps -- Schiit Aegir (two running balanced as monoblocks), a Line Magnetic LM-34ia as power amp, and an old McCormack DNA-1.  All have their unique sound qualities but using balanced outputs from the Chardonnay to the Aegirs is by far the quietest pairing -- in that there's no noise at all coming from the speakers when not playing anything.  With any of the other amps running RCA cables, I get a little bit of noise.  Granted, you have to be right up to the speaker to hear the noise but it's there.  Adjusting gain doesn't seem to affect it at all. The music coming out of the amps with RCA connections is still great, though.  I'm curious about your time with the LSA Warp. I'm inclined to pair the Chardonnay with a solid state amp using balanced connectors.  

@sim_audio_nerd  Thanks!   That must be a really nice combo.  What speakers are you using?  And are you running balanced connectors between the Grange and Coda and have you compared that to RCA connectors?

Just upgraded my Chardonnay with a new remote control. Nice heavy aluminum and just the 2 buttons I need. The remote Mick supplies is fine but this just has a nicer feel and no unnecessary buttons. Easy to program. Sounds better too. ;-)

 

@sim_audio_nerd i bought it on Ali Express.  You’ll need your original remote to teach it but it’s very easy to do.

@jslateiv  Thanks!   The noise makes me wonder if a better motorized pot would be an overall sonic improvement but not sure what to even change it to or how.  That little bit of noise is a worthwhile tradeoff for how good the preamp is. 

@gryphongryph Thanks!  Good to know it's the same on your preamp too.

In completely separate news, a 6SN7 died in the Chardonnay last night.  I was listening to music, heard a loud unpleasant sound from my right speaker and then the speaker went silent.  Swapped around amps and speakers just to troubleshoot that they were working fine and then started swapping tubes.  Visually, the tube looked fine, maybe a little dimmer than the other, but it was pretty dead sonically.  Had a nasty ozone-like smell to it.  Luckily, had a backup pair of tubes.   Have never experienced that before and it definitely surprised me.  

Any new production 6SN7 that anyone would recommend?   I'm running Sylvania GTB now and would like to try a new tube vs a potentially old "NOS."

@evank  Thanks!  System is looking good.  Did you move?  Are you going to CAF?

@tksteingraber  Thanks!  The noise isn’t much of an issue and only happens with remote, so will just ignore it.

@jslateiv Thanks!  I’m going to DM you about something else when I have more time. Really appreciate all the help.

@tksteingraber Glad you like the remote!  The instructions are on the product page on AliExpress but you figured it out.  I think Mick should buy a bunch of these, screenprint a logo on them, and ship them with his preamps.  They’re much closer to the build quality of the preamps than the current remote.
