Douk Audio. Any experience with any of their products?


I've seen several products under this name on eBay in recent history, including a tube preamp board that looks pretty impressive. Especially for the money.   They reference a pretty exotic Audionote preamp in the title.  

Douk Kondo Audionote

I noticed the url on the board, and decided to find out more. Turns out the entire website is blank. Assuming this was an error, I messaged the seller.

"Hi,
I was interested in learning more about the Kondo board, and tried the website to see what info was there, and I get a blank page. Just fyi."

I thought they might appreciate the heads up about the error. Instead, I received this response:
 
"Hi dear customer
wish you have a nice day
the amp board designed by our designers
so you cant find it
best regards
Douk-Amy :)"


Not exactly a confidence builder. I'd be interested to hear if anyone has had direct experience with these folks.

Ok, this is a different model than I thought you were talking about.  This is clearly an active preamp, and does indeed have vacuum tubes.  And yes, it is not passive.  They would do well to get someone with stronger language skills to write these up.  

It might be ok, but one thing I do know.  The vast majority of the finest tube preamps and amplifiers operate on very high voltages.  This is one of the aspects of tube audio that makes it what it is.  This one however only has an 18V power supply.  It is cheap though.  MC preamps are usually in the hundreds if not thousands.

These guys do a GREAT job at a very competitive price!  Bought a Digital Amp from them.  Had some problems getting it hooked up.  They were very responsive and willing to make it right.  User error on my end.  Amp sounds GREAT and very competitively priced.  Liked it so much  bought a phono preamp.  Btw, they were willing to go the extra mile and replace the amp with a new one if we did not get it working.
Hi have a Nobsound NS-01P Tube pre amp I bought used on ebay. I have NOS-Mullard 12AX7 tubes with a vintage Telefunken rectifier tube.

It's about as basic as you can get in an active pre.

The unit is dead quiet and built like a tank.

I am very happy with it, punches way above it's weight class!
I have bought several items off of douk audio. they are primarily a re-seller for chinese gear manufacturers. Their EAR phono stage clone is really good, as are their tube pre amps. Great value for the money.
