Mostly favorable review in the January 2023 Sound on Sound. They like it especially for guitarists (built in tuner). They said “low latency performance isn’t amazing”. Unique innovations, they said.
I bought it especially for the quality of the Pre-Amps - especially for my vocals, since the Focusrite Scarlett that I replaced more or less has rubbish Pre-Amps, which require a lot of post processing (often over processing) to get the vocals right.
I always record with "Low latency" mode switched on in Logic Pro X - otherwise I find, the timing and tempo of all the recording I do seems to be all over the place - and much worse than my performances. Neither the upgrade of Mac nor the upgrade of this MBOX Studio has changed much about that.
Though I am not Chris Squire (ex- Yes bass player "whom Trevor Horn claims could hear 2-3 ms off) and my skills probably are below average, I can still hear if something is not tight enough.
This "box" is fairly new, and I assume/hope that future firmware upgrades may improve a thing or two.
