Who wins on what

Ranked by what users actually praise

Overall Impression

Handy switching features win fans despite the price. Owners repeatedly praise the mono button as a genuine time-saver for mix checks, and the ability to instantly A/B between two monitor pairs or switch between two computers/sources is called a feature they didn't realize they needed. Several use it daily to toggle between work and personal setups, or to add a secondary speaker like a mix cube, calling the unit's lack of a power adaptor a bonus and the workflow 'perfect' for small studios.

Many users report real volume loss and signal degradation. A recurring complaint is that connecting the Big Knob causes noticeable volume drop even with the knob turned all the way up, forcing users to compensate on their interface. Some also perceive a decrease in audio clarity or 'lushness' compared to a direct connection, and one high-end setup owner described the drop as a dealbreaker, calling out hum and loss of clarity through expensive monitors and a sub.

Long-term reliability is a common concern. Multiple owners describe the volume pot becoming scratchy, popping, or mismatching left/right channels after around six months to a year, with some pots sealed and hard to clean. Others report intermittent channel dropouts fixed temporarily by wiggling cables or connectors, buzzing at high volume, and flimsy buttons, though a few users found contact cleaner resolved the noise issues for a time.
