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.

@cal3713 yeah I am that user, need to add that the DHT sound is very pleasant and I could listen and enjoy it very much as it is very special, just not on a daily basis.
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
I have the Supra at home, amazing preamp, dual stages, one warm stage one analytical, roll tubes and choose your poisson, it is a versatile preamp.
I haven't heard the LTA (don't know why I got confused with the David Berning one)


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?



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)

Markus I believe you when you are saying not intending to slam anybody else but the result will be that, in fact the result might even be slam the Supra, I have experience with different pre’s and everyone is different for good and bad and it wouldn’t be fair to compare these, specially on a Supra thread, I know is your thread but I am going to pass and I think others should too.
I love my Supra, does bass extremely well (like a SS), the cheap stock Russian EH tubes sound incredible (this have put in perspective my opinion about rolling tubes, it is not the tubes so much but the designers purpose with it), my wife likes the chrome and the wood matches her furniture perfectly (now that’s a big plus as she gets off my back, she asked me and I had to invent a story the preamp someone sent it to me to tune it, she doesn't know I purchased it), it is very musical and enjoyable, you have dual sections (mine is the cab dual) today I tested levels SPL, Mick matched the DHT and 6SN7 sections perfectly.

Like everything in life the Supra has tiny little shortcomings when compared to other preamps, but that doesn’t mean is not a great preamp,
It is the same as the gain bypassed on the DHT stage, I measured it yesterday. IOW max gain is the same on each stage
Does anyone know the Cabernet Dual input impedance and sensitivity, I can't find any specs on the site.thanks
@gryphongryph hey maybe I missed it but have you tried the EML 45 vs 6SN7? If you can try it, solid plates not mesh, I tried good NOS 45 but prefer the EML
On the Cab Dual Mick recommended to stay away from the mesh plate tubes, was it the current draw?
Sure you can use these, I was just talking about Micks recommendations, specifically not using a tube using more than 1.5A of heater current
Anyone care to comment on the new Grange preamp? I don't recall seeing any comments about the sound.
Which flavor do you have? DHT dual active? You using mainly a TT with it or digital too?

@reimarc thanks for posting

Could you share a picture of the Linlai that came with the preamp?

For 45 try the EML 45B, I personally like it 

 

 

Hi @reimarc 

The reason I asked about the Linlai's is that these are supposed to be good tubes but the stock you received could have been different. There is a thread about these, the ones with the E are supposed to the best and the Linlai letters on the tube are running vertically.

There are some others the letters run horizontally and some have described these as different.

That's why I was trying to find out the ones that did not work for you which specific type were
