Purchased a 2-headed USB cable (separate power and signal legs) from Douk Mall on Ebay . The first one they sent did not work. Not sure why...but DOA (as was a 5 V Enercell power supply I bought from a different US-based Ebay vendor). Bad luck on my part. Douk Mall put a new cable (this one works) in the mail to me before they ever got their defective one back. They were responsive via email though it was obvious English was not their first language.

Thanks for the responses. Glad to know they make good issues with failed products. I'm really interested in finding someone who actually bought either a tube kit, or a completed tube amp product from these folks. While they appear to have some good bargains, especially on the kits and boards, I have yet to find any real reports of experience with them.
I bought a from Doukaudio a tube 6n11 preamp buffer and I just received the package MUCH sooner than expected and was packed extremely well. I'll be able to give a listen in a day or two. It looks extremely well-built and I'm hoping it sounds as good as it looks! Larger than expected dimensions. Will post a follow-up.
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.
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.
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.
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.
I glad to see this thread...I am looking to maybe take a leap with their tube amps' not intergrated....they are like 248.00 and up On Ebay model NOBSOUND HI FI EL-34 single ended Class A 34 amp 13W 245.00 for 245.00 I'm must be total crap... just dont know....If I had 1k to spend, Id buy something we all know...any comments are appreciated on this...Thanks Otto
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.
I got their DAC on Ebay. Quite impressive. I'm very satisfied. Integrates well into my all-Herron Audio electronics. I use an Onkyo CD player as a transport, co-ax works better than optical. Intend to integrate a PC as a streaming source to the DAC.
I understand they made some recent modifications to their DAC power supply, so their current performance might not be the same as previous.
I bought from Douk on eBay an integrated amp with an LED dot matrix display - I think the same (or similar) to the ones found on Mark Levinson preamps.
It’s a hybrid unit - 70W rated power output with a 5670 preamp tube in the front end.
Just 2 analog inputs and one USB in.
It says "A.Audio" on the front - no other model numbers shown.
I’ve had it for a few months now, and it works fine, and sounds decent (at least to me).
I mainly got it because I’m into equipment that has LED displays that I can modify.
Overall, I’m pleased with it.
Hello. I have a DOUK AUDIO USB DAC. It replaces my previous Muse DAC.
In comparison, the Douk sounds much less congested and the music comes alive with lots of detail, a solid base and great imaging.
I did have a problem with the driver that came with it.
I was getting TICS and TACKS at random while the music was playing but not on pause.
I tried everything under the sun to get rid of it but could not find the problem as I thought the problem was with my Dell D-630 when in fact it was with the Xmos drivers.
I did an update and now the problem is solved.
This DACsounds great.
I bought their Dartzeel NHB-108 Clone. It's nothing short of amazing, by FAR the very best amplifier I've every owned ( and I've had Krell, Spectral, MBL etc, etc). The build quality is extraordinary. They also shipped super fast too. Couldn't be happier, in fact I like it so much I may well buy another one.
I got the "6j1 Valve tube pre-amp preamplifier bass on music fidelity X10-D"
the ad exactly. For $13 bucks. It was an easy kit to build, tiny but I have to admit it held up.
I first put it in between a emotiva DAC and threadhold stasis amp. First my Maggie’s, wasn’t impressed. Laughed cause $12 I’m glad it made sound. But.. it started to warm up and sure I can hear that tube sound. Hooked up a pair of speakers with ribbons. It continued to open up.
My preamp is a audible illusions modulus 1 tube and This little plastic pretty blue light toy sounded pretty good. damn well worth the $13 I spent. Perhaps,
Improving the cheap components like caps and resistors would make a serious difference. Tubes of course would make a serious deference.
The little engine that could. It's a fun hobby.
Any particular tubes work with this size tube? These are smaller them
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 Bennett.
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.
