The K-05 Super Audio CD player is the core model in the K series, following the legendary K-01 and K-03 players. The first version of the K-05 was launched in 2011, and in 2015 this evolved into the K-05X. The K-05X instantly became a top seller because of features such as the VRDS-NEO Super Audio CD transport mechanism. This mechanism uses a unique construction that enables it to provide an outstanding level of musical performance, which is why it was adopted by a number of other world-famous high-end audio makers. In its third generation form, the K-05Xs, incorporates the best qualities of Esoteric's flagship model, the Grandioso K1. It combines established class-leading features, such as the VRDS-NEO (VMK-5) mechanism and a high-rigidity aluminum chassis, with the latest K1 DAC platform employing a new dual-mono D/A converter, high current output buffer amplifiers and a new power supply.
