Early December, while I was in Lisbon, I noticed write-ups about a new digital-analog-converter from Astell & Kern, called the HC3 – link. It uses the ES9219MQ chip from ESS, is very small, and can be plugged into laptop with USB-C. The HC3 also comes with an adapter for the iPhone’s Lightning port. Price is around $200 and available sometime soon, in February I think. While looking into this DAC I came across this one, the Go-Link, made by an English company called ifi-Audio.

The chip in the Go-Link is the same one that powers the HC3. The Go-Link comes with a USB-C plug plus a Lightning adapter for the iPhone and an adapter for a USB-2 port, for computers that don’t have USB-C. I found the Go-Link at BH-Photo (link). The price is $59. The A&K looks cooler, perhaps, but is it nearly four times cooler? Plus, the Go-Link is available now. I pre-ordered in December and it arrived this morning.

I immediately plugged the Go-Link into my phone and used my Euclids to listen to a variety of lossless files (16/44.1 downloaded files on Apple Music, 24/96 files on Dropbox) and, while direct comparison is not possible, my impression was that the music felt more alive, more present, more dimensional. I really think this is the tool we were waiting for to be able to listen to high quality audio while on the move, without breaking the bank. Only a year ago, listening to this level of quality meant having a DAP (digital audio player), which costs at least $500 and can go up to $3,000 and more. And it’s one more thing to carry around. Now that Apple Music has caught up to Tidal and one can download hi-res files and play them back on the phone, or if one uses Dropbox in conjunction with a player-app like CloudBeats, the last barrier was how to get digital sound from the phone to your headphones. Bluetooth is practical, and I use it myself, but doesn’t sound very good. There were DACs, of course, but they weren’t tiny and they weren’t cheap. This Go-Link is the missing link, perhaps. I am psyched.

    That ES9219 is a pretty nice chip. Not sure what’s up with the Astell & Kern price point. ESS looks like their engineering team is in B.C. Canada. Fab is probably in Taiwan (like most of the rest of the non-Intel world) … price point of this chip is < $10/each. I may get one of those Go-Link … looks like a nice DAC.

      I was shocked at how much better this sounded. :-)

    And Apple has really pee’d in their Cheerios on their Bluetooth implementation.

    viz., Apple STILL doesn’t support APTx or LDAC. So, on the Apple platform for HD audio, Bluetooth is a non-option.

      Agreed. I appreciate learning a new phrase. :-)

    Thanks for sharing – I just ordered one

    I recently switched from Audioquest Dragonfly Red to the MoonDrop MoonRiver2. The Moonriver2 uses 2 Cirrus Logic DAC chips in its implementation, and it sounds really great. It can even power full sized over-ear headphones, decode just about anything out there, and it even has a balanced output jack.

    Not quite up to the quality of the Chord Mojo, but since it is a simple dongle, it is a super clean solution.

    By the way, Ottmar, you can get a usb-c to lighting cable and make your chain simpler, for the MoonRiver 2, which is what I use. So, one 6″ usc-c to lightining cable from the Moonriver2 to my iPhone.

      Hi Stephen – I haven’t seen new music from you for a while? Are you not actively releasing music anymore?

      • ottmar

        Ali, have you checked out Stephen’s page on Bandcamp? He releases music there all the time. Take a look!

        • Ali

          Thank you, Ottmar. I will do that today!

    Got my Go-Link yesterday (20230105). Really nice sound. Thanks for the advice: that’s a keeper!

    • ottmar

      I am so glad. I am really impressed with the sound. Game changer, I find.

    Ottmar and all posters here-thank you for the information on the Go-link. I ordered the last one on Amazon and it arrived today, 3 days earlier than scheduled. Anxious to try it so, even with iPhone and beats 3 a definite improvement and will try with my Shure SE846 IEMs. For Bluetooth earbuds I have been enjoying the new STATUS Between Pro- 3 drivers and although a bit odd looking, they sound better than most Bluetooth
