Our original and bestselling USB DAC with Sabre ES9023 DAC chip, Savitech SA9023 USB receiver. The newest batch of this DAC has improvements in the PCB layout and comes in the new case with the Hifime logo.

The HiFimeDIY ES9023 DAC was developed by DIY (do-it-yourself) enthusiasts for the purpose of making a really good but cheap dac that could compete against regular commercial DAC's costing many times as much. It uses a DAC chip from ESS Technology, whose DAC chips are highly regarded. The ES9023 chip is their simplest DAC chip which keeps many of the features of their bigger brothers at a minimal cost. You pay for the sound, not the enclosure. We use a small lightweight simple case, so that you don't have to pay extra for a bigger, heavier and more expensive enclosure. The power supply in a DAC is very important for the sound quality. We use a high end ultra-low noise regulator (LT1763) and extra capacitors to smoothen the often noisy power from USB port. 

The DAC can be used together with the USB Isolator to further improve the power supply quality. The isolator will isolate the power from the PC and give a cleaner 5VDC power to the DAC. We have experienced improved clarity in soundstage and separation using this isolator together with the Hifimediy DAC's.
  • Mac, Windows and Linux computers, do drivers required
  • See the forum thread for Android compability
  • Also reported to work with the Synology DS115J audio station
  • Output from 3.5mm headphone connector
  • Volume Level is controlled by the normal volume control keys on your computer (no need to use the volume control inside iTunes etc.)
  • No drivers required on Mac, Windows and Linux
  • Normal line level output (2Vrms) when connected to amplifiers/preamps. For headphones the level decreases down to 1 Vrms for 32 ohm headphones
  • Quality gold plated headphone connector
Additional features:
  • Usb to optical converter. Outputs optical signal if you connect a 3.5mm optical cable in place of a 3.5mm audio cable. Can be useful for connecting your computer to another DAC without usb input.
Highlights about Sabre ES9023 dac chip:
  • The sound go straight out of the DAC chip and into your headphones or amplifier. It is not needed that the sound signal go through a capacitor to remove a DC voltage, there is no DC voltage to remove! This omits the need of a coloring cap which adds costs and reduces sound quality.
  • Jitter Eliminator! The ES9023 utilISed patented HyperstreamTM architecture and Time Domain Jitter Eliminator.
  • 112db DNR
USB (receiver) chip Savitech SA9023:
  • Accepts 32kHz, 44.1kHz, 48khz, 88kHz and 96kHz sample rates. Many USB DAC's use the cheaper PCM2704 usb receiver chips that can only accept up to 48kHz/16bit.
  • Works in USB Adaptive mode. For a asynchronous alternative, look here.
or Tenor chip: (old version, current batch uses Savitech)
USB (receiver) chip TenorTE7022L:
  • Accepts 32kHz, 44.1kHz, 48khz 96kHz sample rates. Most USB DAC's use the cheaper PCM2704 usb receiver chips that can only accept up to 48kHz/16bit.
  • Works in USB Adaptive mode. For a asynchronous alternative, look here.
ASIO driver:
ASIO drivers can provide lower latency, and is to optional to use.  Asio drivers is only recommended for advanced users, and is not required for normal audio playback.
Savitech asio driver available here.
Tenor Asio driver for TE7022 version can be downloaded here.
Output levels:
  • Open 2.2Vrms
  • 4.7Kohm 2.1Vrms
  • 1.8Kohm 1.9Vrms
  • 510ohm 1.5Vrms
  • 330ohm 1.3Vrms
  • 30ohm 1Vrms
Note: Normally amplifier inputs are from 10K to 100K ohm. Normal headphones are from 32 ohm to 250ohm.

I must say that I am impressed. It definitely sounds better than Xonar DGX. Much better soundstage. Cannot get any better for this price.

Instead of doing a subjective testing, I decided to do a proper test with RightMark Audio Analyzer (it is free and you can do it without any having to buy any fancy hardware). The frequence response (multitone) for the Sabre DAC from range from +0.01 to -0.07 dB, Build-in audio range from +3.3 to -10.99 db (Closer to 0 dB is better. Every +3db = double in volume and -3db = half in volumne) The frequence response (swept sine) for the Sabre DAC from range from +0.0 to -0.0 dB, Build-in audio range from +6.4 to -8.0 db. I wish I could put in an image of how bad the build in soundcard fluctuate. It is all over the place with no smooth curves or flat spots. Noise level, stereo crosstalk, ect. are drastically better. In summary: The output is as close to perfect as one can get. No matter what you connect to this DAC, this DAC will make a big difference in improving the sound quality. For this price I would not buy anything else than one of hifime's DACs.

I have always been fascinated with Hifime product, so I decided to take the plunge and purchase the HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023). I have the Dragonfly USB DAC by Audioquest so had something to compare with. To be honest I was very disappointed. Unfortunately the hype was build up to such an extend that the whole listening experience was very disappointing. I did a lot of A/B listening between the Dragonfly DAC and the Hifime DAC using my audiophile Sennheisser headphones. The HiFime DAC stripped the life out of the music with very deep and muffled tones, stripping the individuals guitar, bass, cymbals and muffling them all together. I really thought something was up with my settings but as soon as I would plug the Dragonfly DAC in, the music and each instrument would come back to life, adding clarity and enjoyment to the music. Very disappointed and somewhat sad as I wanted this Sabre DAC to shine. Also, the packaging and unit is cheaply made in China.

Pleased to report that it works out of the box with Matricom G-box running SPMC on Android Lollipop with no configuration necessary. Audio levels might quite low in that case so be sure to bump your software volume controls up to at least 75% if you don't hear anything, but now that I've got the levels adjusted it works great passing audio to powered desktop speakers.

Paired this with a mid 2012 MacBook Pro using both MTX-M50's and HD600's run by a LD MKII and also with LD MKIII. Spending hours switching headphones straight out of the MacBook and the DAC, then the amp there is very little difference, if any, honestly. I ended up returning the Little Dot amps and the HD600's because the $600 difference just wasn't there. I kept the DAC because I felt there MIGHT be some difference and it was only $42. Perhaps I expected a light to come on in a dark room but that wasn't the case. If I have to spend hours trying to hear the difference, I'm glad I did not spend more than ~$40. For those that have computers/sound cards that are lacking, perhaps this will help. Don't expect miracles from a MacBook, at least the model I am using. I don't know about the newer ones; seems they are cutting more corners every year.
