How to choose
Do not buy on 192 kHz alone. In a browser the system often negotiates a practical rate such as 48 kHz. Clean gain, stable drivers, headphone output, direct monitoring and enough inputs are more useful criteria.
- recording use and room
- connection and total system cost
- noise, monitoring and latency
- manufacturer-verified specifications
- availability, warranty and counterfeit risk
Bottom line
SSL 2 MKII leads for features and two inputs, iD4 MKII is strong for a solo vocalist, Scarlett Solo is the safe mainstream choice, AudioBox GO owns the middle budget, and M-Track Solo or UMC22 are simple entry points.
