Imho, Aeta stuff sounds terrific, TONS of clean gain with killer limiters and excellent converters. But yes, the overall design and appearance is quite less attractive than SD or Sonosax gear, with a few bothering things like non bolted Lemo-6 and Lemo-4 connectors (on the Mixy). It is nonetheless quite sturdy, and the 4Minx is several steps ahead from the Mixy, with recessed side plates for the connectors, nice looking and solid feeling top and bottom plates, etc.
