I use the M2 for tracking guitar and bass, practice using Bias FX and as a general audio interface for everyday use. In all these fields, this unit has excelled. Easy to use and install, very low latency for recording, also works well connected to Genelec monitors as an everyday interface for the computer. The controls and connectors feel sturdy and responsive. The display is excellent for tracking input clipping when recording and setting gain on, for example, guitars.
Plug-and-play usability combined with a rich feature set (proper display, loopback-recording, independent direct monitoring and phantom power for inputs) make this a recommendable unit for home recording, despite the slightly higher price compared to competitors products.
