If I get the low-latency problem sorted out and if the audio quality is confirmed to be good by some more scientific tests, it would be hard to find a better audio interface for that ridiculously low amount of money. I haven't tried it on my Window s PC, so I don't know if the drivers work OK and hassle-free.Did not check the mic-preamps as I have no use for them (I have a BAE 1073MP.) and I don't expect anything worth writing home about.Audio quality: Sounds good to, but I haven't done round-trip audio tests or any measurements.My MBP is a 2015 4-core i7 2.9GHz 15" with 16 GB RAM /1 TB SSD, so it's 2x more juicy than my old studio desktop PC (Core ), which interestingly runs rock solid with my M-Audio Profire 2626. But I don't know if it's a CPU- or audio interface-problem. The 204HD gives me way less crackles at 64, but still there's some. I do get a lot of pops and crackle using the Macbook Pro's internal audio interface. Low-Latency performance: My expectation is to work on a buffer size of 64 samples maximum.What I can't tell currently (but can check): Worked, but I remember some unexpected levels (like no Pad needed with passive pickups). I remember needing to use the Pad and Input Gain to get a proper DI input level for recording my guitar into Logic.All i/o's appear in Logic, Maschine, Live as expected.


The headphone output can be very loud, which is good.

It's quite heavy with a metal case, knobs and connectors seem very solid. I have a UMC 204HD (2 in 4 out model) on my MacBook Pro that I am using occasionally and can give you info about some aspects of it.
