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.

Douk did not strike a good chord with me. I ordered a pre amp kit, board with some sockets and heat sinks, 24 dollars total. Not too bad, the board was good. The trouble begins when I am looking for a schematic or parts list. Their response was that the schematic is encrypted. The parts list is the circuit board. I have been making these type of kits for over 30 years. Even the basic kit gives you a shopping list of capacitance, resistance, voltage ratings, tolerances of these and so on. If I cannot decipher your board, don't insinuate that I am unqualified. I have been a tech for 30 years now. I have been unable to find out any more info on this preamp on the web.
