I bought this small device some time ago, more from curiosity, never listen to any ESS Sabre chip dac before. I wasn't impressed first time I listened. I used to listen with Centrance DACMini and Audeze LCD2. I used DACMini as headphone amp with U2 as dac. I also tried with Westone W3 and I couldn't say I liked better as before.
In the meanwhile I acquired some AKG K340 and decided to try it again, since 3D imaging was the forte feature of K340 vs LCD2. This time I was really impressed by the U2 sound vs DACMini's dac. Even if micro details were less precise, the sound was better localized as soundstage, sound seems to flow naturally, with better depth. Comparing to U2, DACMini's dac appear to be more 2D than 3D.
Very good sound for price, even better after mod. After comparing with referent design shematic for DAC chip I have replaced output foil capacitors with SMD ceramics and great amount of detail was emerged, though on some recordings now it sounds too bright. Compared with Micromega Mydac (after mentioned modification) I can't hear any difference, which is strange since they use different DAC chips.
Today I received my HIFIMEDIY SABRE U2 ASYNCHRONOUS USB DAC & HIFIMEDIY USB ISOLATOR,WOW this truly is a great DAC. I'm pleased I purchased the isolator with the DAC it is a must. It is like buying a new Amp,the sound quality is fantastic with full rich sound and clarity.All my music is in 24/48000Hz Flac and I can really appreciate the music now.It runs into a 100 watt RMS per channel amp driven into 12" woofers & 8" midrange & 6" dipole speakers.Mounted into 1/2" thick MDF enclosures I Made myself , so I am pretty happy with the performance of this DAC. I would recommend both products to anyone.I give it 5 STAR'S. Oh and the delivery to Australia was really fast.
Thank you so much for this DAC is a big improvement to the sound of my laptops. It is sufficient as well as my Beyerdynamic DT 990 PRO 250 ohm. Very fast delivery highly recommend it.
I bought two items of this tiny DAC, one for me and the other for a friend of mine. It is perfect for listening through my Klipsch ProMedia Ultra 2.0 enclosures or my Q-Jays earphones. The ASIO driver enables to bypass Windows sound mixer. The only con is the weak output level which prevents from using high impedance earphones.
Unfortunately, I have not been able to try it with my high-end HiFi system yet, because I have been away from home for months. It would be interesting to compare this DAC with my HiFi DAC, an old Stello DA220 Mk2, connected to a desktop PC through a M2Tech HiFace USB>SPDIF interface.
