Kalman Rubinson reviews Anti-Mode X4 in Music in the Round #97: Hegel C53 & DSPeaker Anti-Mode X4
"I'm happy to tell you that DSPeaker's Anti-Mode X4 is great just as it is, and will appeal to user needs that until now have not been addressed. This is a first-rate two-channel preamplifier with flexible bass management and potent DSP for setup and room EQ. It requires no additional parts or a computer—everything is already built-in or is supplied by DSPeaker. Even better, it requires no additional technical background"
