The B6 is for (semi-)professional musicans that won’t invest in an API Box 2 or a SSL Origin, while still seeking for the clarity, flexibility and a bit of the mojo of legacy SSL consoles in a small footprint.
The B6 is the centerpiece of a modern hybrid studio ecosystem - for a reasonable price. It’s fun to track and mix with the B6 and it’s even much more fun to connect some high end outboard to the B6 - e.g. preamps from NEVE or eqs from ELYSIA - to go much further.
