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.

Thanks Bill.  That's great to hear.  New components go through a break in period, so it's understandable the sound improved over time.  It's great to actually hear about the sonics of one of their products.   They seem almost too good to be true for the pricing.  I was a little skeptical when I could find no mention online from someone who had actually listened to one.  This hybrid looks very interesting.  

Thanks again.

Well... Today I took out the Chinese 12AU7 tubes which came w/the unit and put in the 1958 RCA tubes that I bought recently just for this pre-amp/buffer. Night and day difference for the better. What a great way to experience such musical sound for so little $. (Maybe the stock Chinese tubes needed more break in? But I have not read on the internet any praise for Chinese tubes, so decided to change out. Glad I did.)

The Chinese tubes themselves are bound to be the weakest part.  Western NOS are best in breed, then the (former?) soviet tubes, and finally Chinese.  It can be quite surprising as to what a difference this can make.  Seems the chinese electronics like this example are quite a bang for the buck.  

Thanks for the update.

This is one of several pieces that interested me.  For a single ended tube amp of this sort, the price is dirt cheap.  I did notice that what appears to be the same amp on Amazon, received several good reviews.  

One thing that did put me off was the response from Douk when asked for more info.  I wasn't necessarily looking for their deepest design secrets.  Although they claim the preamp I was looking at is based on an Audionote design, which is also puzzling.  You could not buy the raw parts alone for these prices, so it is tempting.
