  3. There are 3 working modes with 2 different sound effects, supporting simultaneous output of AK4493 or ESS9038Q2M to groups 1 and 2, or AK4493 output to group 1 and ESS9038Q2M output to group 2.

Device works as expected although the lack of providing DSD drivers (no download link, you have to contact support by email for them) and poor documentation for OpAmp rolling. They lose a point for each.

Nach dem Auspacken des Q11 folgte die erste Überraschung. Das Gerät ist sehr gut verarbeitet. Der Acryl Glas Deckel gibt den Blick frei auf das blitzsauber aufgebaute Platinen Layout samt AKM und ESS Chips. Die Beleuchtung nach dem Einschalten im Innern ist einHingucker. Mit der beiliegenden Fernbedienung lässt sich der Q11 zuverlässig bedienen. Soweit so gut. Nun zum Klang der beiden DAC 's. Gehört hab ich mit einem Top Kopfhörerverstärker von SPL und dem Hifiman Arya SE. Als CD Quelle kommt bereits seit Jahren mein Onkyo Laufwerk zum Einsatz.Natürlich gönnte ich dem Q11 einige Stunden Einspielzeit.Gleich vorweg, einen großen Unterschied zwischen dem ESS und dem AKM Chip gibt es nicht wirklich. Beide DAC's klingen grundsätzlich hervorragend.Der ESS 9038Q2M lässt Musik einen Hauch klarer und detaillierter erscheinen, wärendbeim AKM 4493 Musik vom Fundament her aufgebaut wird.Der ESS überzeugt mit großer Bühne, der AKM kontert mit etwaskleinerer Bühne, dafür mit einem Hauch mehr Körper.Aber Achtung, der Unterschied ist extrem gering. Ohne vieler A/B Vergleiche mit unterschiedlichsten Aufnahmen ist es nahezuunmöglich die beiden DAC's auseinander zu halten. Natürlich ist das positiv zu bewerten. Beide DAC Chips spielen in der gleichen Liga. Was man bevorzugt ist eher Geschmackssache als ein Qualitätsmerkmal. Beide klingen auf audiophilen Niveau.Mein Fazit:Toller DA / Wandler zum Knaller Preis. Kaufempfehlung? Aber sowas von!

This is a great basic DAC (no filters, EQ, balanced outs or headphone out).It features two different DAC circuits in one box.How different they sound is based on your ears and your equipment, but the choice is there for you to explore.Contrary to some reviews, you cannot combine the two DAC’s into one signal.Your choices are AKG to both outputs, ESS to both outputs or AKG to output 1 and ESS to output 2.I find both circuits sound very good, plus the device looks cool with its two screens and soft LED glow through the clear top.Well worth the $150 or so that it goes for.

It's a pricey bit of kit and I did my homework. Watched loads of review videos and this unit kept coming up so I thought why not. The difference this unit has made to the sound of my cd's is remarkable. Right through the complete sound range every sound is crisper. Bass is clearer. No distortion when I the volume went up and trust me I took it to max volume. Tried rock, trance etc and it's fantastic. I would love to try more Douk Audio produced. Great clarity and build quality. I highly recommend it. Well done Douk Audio.

I purchased this after checking lots of reviews on-line and videos. I have to agree with most of the reviewers regarding chip mode sounds. ESS is bright, AK is smoother, combined was best for me tamed the brightness and still had plenty of clarity. I think it is a cool idea, just not a good as could be or as I was expecting. The problem for me is mostly the soundstage, it just wasn't there in any of the modes. After extended listening I found that my Douk Audio HiFi tube DAC sounded much better, has much better soundstage, and with the tone controls able to duplicate all of the Q11 modes easily and much more. I really wanted to like the Q11, build is good, looks good, fair price, just fell short on sound - my opinion. I'll be staying with my Douk Audio Hifi Tube DAC for a bit. Yes, these are cheap DACS and one can't expect too much, however, I did expect Q11 to sound better than the old model, much cheaper, discontinued HiFi tube DAC. Love what Douk is doing, and I have plenty of their products - just not this one.
