Audient iD14 MKII

Setting up this audio interface for the first time was some of the worst experience I've had with any hardware, and even afterwards it's just a thousand paper cuts.

The interface randomly disappears from the list of connected devices, one speaker is sometimes louder than the other, I often have to reset the volume after reboot, the knob doesn't have a start and stop points (turns infinitely around) which feels really bad even compared to my entry-level Scarlett Solo.

Unless you have no other option I'd avoid this brand.

The most "popular" review on this site is a disgruntled customer who may have received a unit that got past inspection in poor order or else was damaged in transport. This does every other positive an injustice. My experience of this unit after two weeks has been excellent so far.
Pros:
DA Conversion: Superb - I have interfaces from Zoom (R8), Tascam (US 16-08), Behringer (404HD and UMC 1820, ADA8200 Pre's), Native Instruments, Maschine Mk 3 and ocassionally I use the Digitakt as a DAC when operating in a DAW. I can safely say my unit has by a very audible margin the best output audio quality of any of the aforementioned. The Behringers may beat it in output volume (the 404HD in particular) but the claritiy of the audio with the ID14 is exceptional.
2) Loopback: This features allows you to flawlessly record incoming audio from any source within your computer directly into your DAW. A particularly nice feature for podcasters and OBS users as well.
3) Build is excellent, but I expect that from a "premium" product.
4) 8 x 48K ADAT inputs. This means I can offload the UMC 1820 and the Tascam and upgrade my monitors :)

Cons: wish it had a 5 pin din in/out like all the other units I have.

Highly recommended especially for the additional features.
