Who wins on what

Ranked by what users actually praise

Overall Impression

Switching and routing features are a genuine highlight for many owners. Commenters repeatedly praise the ability to A/B between two monitor pairs from one source, the record-source button's flexibility for calls like Zoom or Skype, and the headphone amp's clean, powerful sound. Several say it solved workflow problems no other reviewer explained, and one called the walkthrough of buttons a big help after struggling with the unit for a while.

Long-term reliability is the most common complaint across owners. Many users report the volume pot becoming scratchy or popping after about a year, left/right channels going unbalanced, buttons turning stiff or getting stuck, and full unit failures requiring repair or transformer replacement. Some went through multiple units or repairs before switching to competitors like Behringer or PreSonus, citing repeated identical faults.

Noise, coloration, and heat concerns worry some users. Several commenters describe humming, hissing, or crackling noise through monitors and headphones, and one detailed the unit turning a sine wave into a square wave at some volume positions, unsuitable for critical mixing. Others note the unit runs hot even with phantom power off, and mic preamps weren't strong enough for certain condenser mics like a Rode Procaster.
