DSPeaker Anti-Mode X4 Silver DAC/Pre/DSP

The new DSPeaker Anti-Mode X4^TM preamplifier/DAC combines an uncompromising selection of audio electronics with more than a decade of expertise in acoustics and signal processing. It was designed with one purpose in mind: to elevate to a new high what is possible in stereo sound reproduction in the domestic environment.

The idea of the industry-leading automated Anti-Mode^TM room calibration is simple: to make the loudspeakers and subwoofers work together with the room acoustics, instead of clashing against it, in order to produce the best possible sound. The benefits of the Anti-Mode correction include vastly improved clarity, tighter and deeper bass reproduction, the absence of unwanted "boominess", and seamless integration of the main speakers and subwoofers.
