MOTU M6chat_bubble_outlineFrom real comments

Reliability is the M6's strongest selling point among longtime MOTU users. Multiple commenters describe MOTU gear as rock solid, contrasting it with unstable drivers on competitors like the Audient id14 and an overrated UA Volt 476p. One user's MOTU 8Pre lasted 16 years before failing, and another calls the M6 a superior replacement for a much pricier Arturia AudioFuse Studio that broke down, citing 'superb' sound quality at less than half the price.

The missing ADAT expansion is the interface's most cited shortcoming. Two commenters specifically note that adding ADAT input would make the M6 unbeatable in its price bracket, comparing it unfavorably on this point to the Audient ID14 and SSL12. One long-time M4 owner feels MOTU 'missed' an opportunity here, suggesting it's a deliberate omission that limits scalability for users wanting to add more inputs down the line via digital expansion.

Some users report software quirks and preamp/gain limitations. One new owner described sample rate conflicts between the computer and connected programs, plus unexplained random static surges, calling the concept good but the software 'a bit bugged.' A separate M2 owner researching an upgrade learned the whole M series shares a fixed 60dB gain ceiling, and another dislikes MOTU's routing software enough to have switched permanently to RME instead.
