Tested by Sound on Sound

Consistently praised

Commonly flagged

  • No Thunderbolt cable included despite the four-figure price
  • Monitor Correction on/off status not clearly indicated in Console (especially headphones)
  • Auto-Gain not yet supported on all Unison plug-ins and not fully foolproof
  • Built-in headphone amps lacked power for a very loud drummer
