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.

the LTA preamp and amp are based off David Berning’s OTL designs. He advised/designed for LTA.
That's why it rang a bell, I heard this preamp at the Florida Audio Show 2019? 2020? man I'm losing my memory (and did not get that C.....), I have been to the 2 florida audio shows anyways, it was good, and neutral, almost like my Atmasphere MP3 but "almost" not the same,

I get tired of saying this, for the money the Atmashere MP-3 is the best preamp on that class, if you like "realism" the LTA is a good choice, I would prefer the Supra Cab Dual as it could give me warmth + realism + bi amping, the LTA could be a little better (slightly better than the Supra) in neutrality but the Supra is a Swiss Army knife of a preamp. To me it is very very unique and Mick is a man that knows what he is doing.

Just my opinion of course.
But listen don't "listen" to the people in the forums, wait for the next audio show and see if you could audition the LTA and maybe get some more feedback on the Supra. I can make you a video with music from your favorite tracks if you want..... I will be setting back my Supra soon (maybe this week don't know yet)

I see you posted on teajays ZOTL thread, that makes sense, the thing is you are comparing preamps that are targeted for either the neutral, realistic, studio crow or the warmth euphonics mushrooms crowd.
The thing with the Supra is I prefer it so far on the 6SN7 stage, I wanted to experience the DHT stage but I was surprised how good the 6SN7 with its stock tubes is.
I am a tube roller but 2 preamps shown me that the tube it does not matter if the designer built the preamp around a specific tube set.

Take Ralph, his preamps with the stock Chinese Shuguang orange base 6SN7 is almost perfect, I tried the others and yeah you get different flavors but the stock tubes are very good and for comparisons I always go to these.
Mick with his EH tubes wow, you need to hear it to believe it.

Neither Ralph or Mick speak much about tubes and tube rolling, they say that yes sound could be improved but their preamps are excellently designed even around the stock tubes.

I wish I could remember the tubes on the ZOTL, very very neutral, not detailed but that could have been the source most likely and very musical and..... Let me find a good adjective, circumspect? Polite?



I haven't tried the DHT on the Supra with 45s, I have em here new production 45s and NOS, dying to try these as they are supposed to be more towards neutral than the 300Bs, need some time.

If you are in the south Florida area you are welcome to come by
Hey, fellow Supratek owners. Got a request for you, and I think it’s relevant for those who might be considering Supratek. Here’s the ask: Please share what other preamps you owned or considered when choosing Supratek.
My only personal comparison was a Naim NAC 82 with hicap powersupply. The Supratek taught me the meaning of the phrase "not even in the same league". In many decades past I'd heard a Covergent Audio Technologies preamp (it was pretty good) and an Emmanual Go First Sound (It was awesome). When I chose Supratek I considered First Sound and the Don Sachs. I wasn't aware of numerous other boutique builders at the time. I wasn't crazy about the looks of the Supratek, but  have grown to love it and now think that exposed tubes are just about the coolest thing to look at in my music room.
A couple of practical features I really appreciated on the Supratek were the large number of inputs and, it turns out, the ability to connect up to three different power amps. Never would have thought I'd need that, but I'm now running a solid state from one output for my quads and a 300B from another output for my 93dB efficient JBLs. Turns out this is a capability I use all the time.
I’m not asking you to go into a detailed comparison (though that would be cool if you wanted to). I’m just requesting you to say what you upgraded from or auditioned against or whatever. BTW, this is not intended as an opportunity to "slam" anybody else’s equipment. Just a place to try to collect and document people’s experience.
