Product Description

SACD/CD Player, 32 bit DAC

The K-03X all-in-one player is designed to offer as much of the stellar performance provided by the K-01X as possible. Using the same design philosophy as the K-01X, it also derives its leading technology from this model. Its VRDS-NEO VMK-3.5-10 drive mechanism now incorporates Esoteric’s advanced VS-DD servo driver for even smoother spindle operation. Its dual mono DAC, also found in the K-01X, is configured with 4 individual converter circuits operating in parallel and summed to optimize linearity and minimize noise. It also employs Esoteric’s innovative 34-bit D/A processing algorithm.

With a pedigree extending directly back to the Grandioso D1, the K-03X is clear in its stunning sound quality, ease of use and wide functionality, including such recent developments as its DSD compatible USB interface.
