Douk Audio. Any experience with any of their products?

I've had a few things from them and have seen them mentioned in other forums. My overall impression is that they build decent quality stuff with designs as best that they can figure by some of the big names. A small dac that I purchased for my brother was very, very good for like a hundred bucks. I would not count on getting the highest level performance, but I would expect great value for the money. 

I do appreciate the info on ebay feedback.  What I'm really looking for is any experience with the sound of their products.

Last night set up my Dug Mei AV-21 I bought from Doukaudio. (Using as pre-amp on top of my Adcam 5002 amp driving Dynaudio DM2/6 spks.) In a word...superb sound. I bought on Ebay an inexpensive input swicher box (JVC) which I will use between my CDP, tuner, record player and CD recorder. Haven't received this yet. I wanted to get familiar the sound to see how much the sound gets affected. Since the pre/amp, tube buffer is passive I had to turn up the volume. No problem at all. In the first hr. the sound was so-so. I heard the potential...the second hr. the sound blossomed. Unit is larger than expected and build quality appears excellent. Using the stock 12AU7 tubes which came w/the unit and may exchange w/some vintage RCA tubes I have in the future. Overall, too new to comment on long term longevity. But for the little $, quite pleased so far. Doukaudio promptly sent the unit (pack very well) and arrived in perfect condition. Hope this helps....Bill.

Dun Mei Av-21. Sorry...

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.
