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.

Jaynewt- which seller did you buy your Dartzeel clone from? Prices are from 800 shipped to maybe $1600 shipped

thank you!!
@jaynewt I'd be interested to know too. Douk sell for $1600ish, but others sell for around 1/2 that. Are they the same clones?
Ref . Douk audio and Amy . I have purchased the Hi-Fi 2.0 Channel Stereo Amp Board Kit/Set_UK and it was the biggest mistake I have ever made. Before I started the build I checked the contents and found that a number of components were missing so I made contact with Douk through Ebay and received a prompt reply from Amy saying would I purchase the missing parts in my country and they would pay .From that I assumed the reply was coming from China even though it was supplied from UK stock , I replied that I was not in a position to do that and if they could not supply the missing items I would complain to Ebay through the appropiate channels . I received a quick reply as follows.... hello dear customer wish you a very nice day OK will resend it the tracking number is JV093944637GB best regards Doukaudio-Amy")..... What they are sending I have no idea.  I am no pro. at building circuit boards and at the age of 91 I thought it would give me an interest having built a number of Heathkit items in the past but I am now in trouble reading the resister coding as no instructions are provided in the kit , just a bag of bits and two heat sinks , HELP.

Albert,  In "My Ebay"  go to "Purchased" on this transaction,  look to the right side, where it says "Leave Feedback", click the drop down and choose "Return this Item".... Tell them the item "Is not as Described"  request a refund... Do it right away.  Ebay will get involved and you'll get taken care of. 
Hello timlub , thank you for advice, it seems that you have to wait seven  days from delivery before one can do that but I have it in mind . regards Albert . (Englebert )
