March 22 update.....sound report after recent (further) upgrades = very impressive. Just spent a couple days playing this up against 3 other good preamps, and this little unit stands strong. Using a very nice Dynaco VTA70 tube amp with good nos tubes. And DC10 Audio Mini Berlins speakers - this combo is very revealing as to tone, detail, imaging, etc.
...Audible Illusions Modulus 2 - decent example worth about $800. Elekit sounds really quite close. This particular M 2 could use a tune up, but is fair to say it sounds typical of a stock unit, and is itself one of my fav preamps. Tube type. Runs 4 x 6922. After I spend some money on tuning and upgrading the M2 I expect the M2 to sound better than Elekit, but for now....pretty much interchangeable.
...$4000 custom tube preamp - Super Blue custom my tech does...runs 4 x 6922. Very good preamp. No the Elekit doesn't quite match it, but its close. Close enough you'll probably make more difference in your sound due to different amps, or speakers, or tube rolls if running a tube amp.
..Classe DR-5L solid state - a beauty example. Considered a very good solid state preamp. Value $1000. Elekit sounds better, quite noticeably so.
Good sounding tube preamp and considered a bargain at the price.
Recently upgraded the pair of 12AU7 tubes (Ecc82) to 6H23 (in the 6922 family). Not sure on what exactly these are - possibly old stock Russian military spec? Just don't know so wont promise.
Please disregard the photos here showing a pair of Electo..something tubes, and also the tubes seen in the "open case" shots...I can't delete these photos for some reason. Tubes have been replaced with 6H23s.
My tech is convinced this the 69 stuff kicks butt on the 12 series. Pretty much all my better tube preamps that I have or have had have run the 69 stuff. Probably my tech had to change out some resistors or bits to make the 6H23 work here, but he's quite capable of figuring that out.
Has phono stage for both MM and MC. The MM really is decent - better than lots of old vintage stages for sure. Havent tried the MC so cant comment.
Also has a switch to jump the Gain from flat to I think plus 3 Db?
Google around and you will see that this is a well regarded tube preamp. Made in Japan.
And this one will slap down a stock example.
Replacement would be about $1200-1300, Pre alone was $880 back in fall of 2016. Then my tech did some significant further upgrades at a cost of over $200. Plus the new tubes 6H23 worth about $150-200..
I also tried a set of NOS Mullard 12aT7 as was told they were an improvement - didn't do much for me actually, not like this last upgrade.
Latest upgrade includes changing out one (2?) of the critical opamps to one better suited for the circuit....the one supplied with the new amp isn't an ideal match for the circuit, according to my tech - who is pretty with it.
Very compact unit. Note the photo sitting on top of a conventional rackmount preamp which is 19 in across. Compact can be your friend.
Nicely finished all metal silver chassis, faceplate and cover. I find the knobs a bit flimsy, but otherwise build quality is good to very good.
Nice blue running light. Will fit in great with a lot of silver face vintage gear - especially Marantz, Pioneer, etc that have the blue light thing going on.
Just over one year old.
This is a good sounding preamp. I've owned and used a few different preamps in past few years, and find this one sounds better than most - and gives much more costly units a run.
It's been an eye opener to run this preamp ahead of various vintage solid state amps I own. Like Sansui Au-9900 and Ba3000, also my rebuilt Kenwood 700M and Technics SE-9600 amps really responded to this preamp.
Tube amps? Yes...works very well with my Dynaco ST-70 variation(s).
Only for sale as I have at least 2 other preamps now that are comparable. I really dont need 3.
On other hand, I wont be giving this one away. Thought perhaps someone out there was interested in one built right, with some extra tasty upgrades.
Normally sold as a kit - but I had the importer Victor Kung personally assemble mine. Cost me $85 with silver wire, but worth it - I am sure my soldering skills (and many other kit builders ) are not as good.
I went with every upgrade Victor recommended. In addition to the following items that he charged me for, he did a couple more upgrades as a bonus. The photo with extra parts may be all that were replaced, or maybe there's some extras mixed in from factory?
TI 2227P Opa-amp (2)
Mundorf Supreme 0.47 (Qty 4)
Amtrams 1/4 W AMRS carbon resistor
Then a year later I took to my local tech for the further upgrades.
Factory double box, manual, 2 sets of tubes (comes with the GE shown - Mullards are installed).
Quite low hours - probably under 400.
No damage, no abuse.
Lowball offers go straight to spam and stay there. Sent one today. This isn't kijiji boys - grow up or move on.
Local sale preferred with audition, but surely will ship. Double factory box so should be fine. Wont be a lot to ship either as is compact and light.
