Because life is funny that way, current Macs (that I've checked) do not support optical output of 24/192 for 2-channel streams. So you will need to use the Toslink input if you want to get 24/192. However, the USB controller only supports 24/96. The AKM4396 converter chip is capable of handling up to a 192 kHz sample rate and a bit depth of 24 bits. Per usual, a microfiber bag is included, but you'll need to get your own Toslink cable.īefore I get into listening reactions, let me clear up some confusion about the D1's sample rate capabilities (confusion because the guide and the features say both 24/96 and 24/192). The D1 ships in a padded box with a gold plated USB cable (mini to USB, 28'). And then of course the AKM4396 DAC has been used in countless soundcards as well as the Logitech Transporter and the CEntrance DACmini (and many more).

The SPDIF receiver (CS8416) is the same used in the Schiit Bifrost (see here). On the D1 (and D2), the TI1020B USB controller chip is 'widely recognized as the industry standard for higher-end USB audio products' according to Audioengine's website. Did they take the same approach with this DAC? Not entirely, so far as I can see. So how exactly is Audioengine delivering for such a low price? In the past, reviewers were confounded by their quality workmanship, which made use of custom parts. Actually, I have a perfectly legit use for it since my office computer's headphone output is buzzy and harsh. I already own three products (A2, A5+, and S8) from Audioengine, so when a visit to their website revealed a new DAC for 169$, it was pretty much a click now and figure out what do with it later situation.
