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.
The unique VRDS-NEO VMK-5 transport mechanism featured in this new model incorporates high-precision turntable that greatly improves reading accuracy by mechanically correcting for disc surface run-out. Its hybrid construction integrates precision-machined aluminum with polycarbonate to help minimise rotational inertia. Formed of high-rigidity BMC (Bulk Molding Compound) and steel, the hybrid turntable bridge also makes a significant contribution to the suppression of rotational vibration and run-out. The transports spindle motor realises further improvements in reading accuracy with an advanced servo control that uses rotation detection circuitry.
The digital-analog converter section has been fully redesigned based on the latest platform used in the Grandioso K1. An AK4493 32-bit DAC from Asahi Kasei Electronics has been combined with premium components and the latest design technology to provide an exceptional level of sound quality. Four converters are used in each channel in a parallel differential configuration, to provide class-leading linearity and extremely low distortion. Like the K-01Xs and K-03Xs, additional buffer amplifiers are placed immediately after the DAC outputs and this gives a more powerful bass and better reproduction of low-level signals. The layout of the DAC power section has been revised to provide further improvements to the noise performance and stability.
