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.

Just ordered a Chardonnay a couple of days ago will be using a Pass XA25 amp. Was told it will take 3-4 months, if they are as good from what i have read it will be worth it.
I`m using a LTA pre now. For me the LTA`s are a little on the cool side. And thanks everyone for the 6SN7 info.
highstream. Mick said he has been very busy during this pandemic.

The reason i decided on Supratek was not only the reviews but reading thru his blogs it became apparent that Mick and myself have the same beliefs in sound and what sounds good and what does not and the whys. And his thoughts and experience on class D amps mirrored mine to a tee. 
As i posted earlier i ordered a Chardonnay. I have been listening to my music lately and thinking how good it presently sounds and i`m starting to question ordering the Chardonnay. I do not want to waste my time and money making a side ways move or even worse a step backwards.

Has anyone had experience with both the LTA pre and the Chardonnay? I do not want to lose the magic that my system presently has.
Decided i`m going to hang in there and wait for my Chardonnay. Thanks everyone for your input.
In Sept.  i had to cancel my order with Mick. My daughters car quit on her and with the holidays quickly approaching the wife said that the pre was going to have to wait and grudgingly i had to agree.

This weekend the wife gave me the green light to place another  order. I`am now looking at the DHT so looking back maybe everything has worked out for the best.
I`ll have to see if Mick is still building the DHT/6SN7 for the special price he was offering earlier this year. That way i`ll have both options.
Did you clean the pins on the new tubes? Also new tubes can be noisy at the beginning.
I own one of the 6SN7/DHT 300B/45 pre amps and it has to be one of the best sounding pre amps that i have owned without spending 25k and more.
No, it's the fact what you posted is not the norm.

And what about your summary? What are you implying? Your experience with a used piece that was purchased ten years ago is what future new owners should expect to experience? The fact that what you bought was used and is not what most have experienced should make you think.

Try disconnecting one component at a time from the pre amp. First the TT then turn everything on. If it still hums reconnect the TT and this time disconnect the DAC then turn everything back on. If it still hums your now down to the amp and pre as the suspects. You could have a ground loop hum. For about a $100 on amazon you can buy the iFi GND Defender, first try it on your amp then next the pre. If that does not get rid of the hum i'm not sure what the issue could be. Good luck.

In my DHT i'm using Cossor WE300b tubes which are a major upgrade over the stock Psvane tubes. For a rectifier tube i'm using a Phillips 5R4GYS immediate improvement over the JJ GZ34, the music is cleaner with an added layer of textures presenting a very real soundstage. The 6SN7's have made the least impact as to sound maybe because of their use as driver tubes, i'm using original Bad Boy's. The Cossor WE300b's are very close in sound to original WE 300b's and for the price are hard to beat i bought mine from VKmusic. The biggest surprise was the 5R4GYS rectifier tube which was a major improvement in sound right from the beginning.
