Features & details

Features

  • With micro USB input and TOSLINK optical / coaxial /HDMI 12S output(can output at the same time), can work well with DAC, preamp, amplifier or speaker. Adopting XMOS XU208 chip solution, with 1000MIPS random access memory much higher than U8 (500MIPS), and more stable than Italian Amanero solution and coaxial output supports DSD DOP.
  • Output interface with DSD ON function can match the decoder that needs DSD ON signal to decode DSD songs, supporting 44.1K-384KHz/16-32 Bit sampling rate and DOP DSD256 at highest, better signal process brings higher sound quality.
  • High-quality components are used to ensure better performance, such as ultra-low noise LDO regulated power supply, LVDS differential chip, gold-plated coaxial interface, OS-CON solid capacitors and Panasonic FC filtering and decoupling capacitors, the contact internal resistance is smaller and the data transmission is more reliable.
  • USB interface can be used as signal input and power input at the same time, and with external DC 5V input (with priority) that can be powered by phone charger or power bank, easy to enjoy HiFi music any time and any where.
  • Mini size with exquisite design, with PCM and DSD indicator easy to show the output format, black aluminum alloy cases look more cool and fashionable, very suitable for desktop audio device to use.

Cheap USB-to-I2S Interface

I purchased this to connect my relatively high-end ASUS laptop to the I2S input of my Musician Pegasus DAC. The sound quality in the Pegasus was better to my ears with the I2s input than with the USB input, so I am very happy with this purchase.

This is the cheapest D2D interface with I2S that I could find. Other (nicer) models cost $250 or more, so I felt this one, at $49.99, combined with Amazon''s return policy, might be a winner.

Minor Caveats:

1. I am using a Windows 10 laptop. For me, the unit is plug-and-play. However (because I read instructions), I downloaded the driver installation program from the URL listed on the product page. The driver installation resulted in the complete cessation of function of the unit. Annoyed, I uninstalled the driver software, and everything returned to normal. Lesson: Don''t download the Windows driver software if your unit works without it!

2. The unit is listed as supporting up to 32/384k file formats. In my Windows system, the max is 24/384--this was also true with the non-functioning driver software installed. Maybe on a Mac or a Linux system. 32/384 may be supported, but not on my Windows laptop.

3. Be aware that if you are using this as an interface for I2S and Coaxial and/or Optical connections, the unit will output to multiple devices simultaneously. If you want to connect multiple devices and have output go to each device simultaneously, you are limited to setting the bit rate/sample rate to the highest of the attached devices, unless you want to keep changing the Windows settings. In my case, I wanted to connect both a Musician Pegasus DAC via I2S and a NuPrime IDA-8 via optical. The NuPrime IDA-8 is limited to 24/192 on optical, while the Musician Pegasus DAC can support much higher rates. So, if I set the Mini XMOS XU208 at 24/384 in Windows, there would be no acceptable output to the NuPrime--if I wanted both to get the signal without changing Windows settings, I would have had to set the device at 24/192 in Windows. So I decided to keep the the unit at 24/384 and use it only for the Musician Pegasus I2s; I disconnected the NuPrime IDA-8 from this unit and attached the NuPrime directly to my laptop via USB.

If you are ok with these limitations, I definitely recommend this as the cheapest way to get an external I2S interface at the current time.

Thought my Gustard X16 sounded fantastic and better than even some $700-$1000 DACs I''ve heard so I was plenty happy. Saw someone post about using these as an I2S reclocker on their DAC and decided for ~$55 it couldn''t hurt and if it straight sucked or didn''t work it was an easy return. Plugged it in to my PC and then into my DAC through I2S over HDMI and instantly noticed the channels were swapped but no problem, just swap the output cables on the back of the DAC and problem solved.

THEN THE SOUND. OH MY GOD IT WAS NIGHT AND DAY BETTER.

Lows dug way deeper and hit harder. Highs were more detailed and separated. Mids were very noticeably clearer but didn''t stand out as being as massive of a difference as the lows and highs....but mostly the lows...oh my god the lows came out. Soundstage width, depth, and height was improved and I think it was because of how much more accurate the attack and decay was to give that much better sense of space. Imaging was noticeably improved. Really everything was noticeably better. If you search them online they have 2 higher tier versions with more expensive internal clocks. One of them is ~$100 with TCXO clocks and the other has 2 Crystek femtosecond clocks and is $200. With how noticeable of a difference this thing made with my Gustard DAC I''m honestly tempted to try one of the $200 ones. At $55 this thing is a steal for the performance it brings if you have an I2S over HDMI capable DAC. Douk Audio really has some decent stuff these days, it''s crazy.

First off, I''m a sucker for detailed product description so this thing really caught my eye, especially considering the price. And I''m a sucker for Panasonic parts. I like the gold plated option for coax as well, that''s a nice touch and attention to detail. I initially thought I would get 32 bit audio from this using the coax or optical but that turned out to be a hard lesson learned. But I do get a quality 24bit/192khz sound utilizing the optical. I liked it so much in comparison to others I''ve bought and tested that I decided to get a second one. So one for my Windows PC and one for my Nvidia Shield, both running 24/192 via optical. Other than the 32 bit misunderstanding on my part -- I think this is a quality piece of audio equipment all things considered that shouldn''t be passed up unless you''re dead set on getting up to 32, which apparently you can do with the I2S option if you have that at your disposal. I don''t, but there''s nothing that really competes with this thing in it''s price range.

This device can benefit you if you want to feed a DAC that doesn’t have a USB input or if you have a DAC with a lower quality USB interface. But if you already have a DAC with high quality interface, then there is little to no benefit, and could even be worse. Being my Chord Qutest’s USB interface already has galvanic isolation, there was no benefit to using this device with it. Technically, there could still be benefit to feeding the DAC via coax or optical using this device because that would allow the DAC to power off it’s USB interface and thus less RF interference being generated. However, due to galvanic isolation in the Qutest, that basically becomes a non-issue anyway but, of course, I did try it anyway just to see how everything compared both with and without it. With the this device in the chain, I found the sound to have some treble glare and edginess that I did not have when this device was not in the chain. Basically, it gave a more fatiguing sound. That being said, this with my experience with my exact equipment. Your mileage may vary. I could definitely see this device being more helpful if your DAC (or USB interface of your DAC) is currently the weakest link in your chain. In that case, I’m sure it can give your some benefit. Obviously, there are also different use cases for a device like this so it may be very useful in a different use case. It did seem to do the job it was advertised to do, just not to the level I was looking for in my particular set up.

This thing works perfectly right out of the box; it allows me to stream a much higher quality I2S digital signal to my PS Audio DAC. That allows the DAC to playback all file formats natively and in 32-bit (where applicable), and that''s a huge performance gain, especially with native DSD files vs. DoP (DSD via PCM). And the parts selection of the internal components is superb; it''s hard to believe that it can be manufactured with this level of quality at this low, low price point. I loooooove this thing!

This thing is pretty much perfect. I have it hooked up to a KVM, acting as the sole audio sink for several computers (one at a time), and have it simultaneously feeding a headphone amp and a speaker amp (either of which may be turned on or off as needed).
