Japanese original Esoteric K-01XD SACD player turntable MQA decoding audio player brand new genuine licensed warranty
The K-01XD is very similar in appearance to the past. Esoteric does not have many obvious differences in the appearance of each different model of equipment, and it can usually be seen through the model label on the front panel.
K-01XD is an advanced and brand new model in the K series, but it is not the flagship model of Esoteric. On top of the K series, there is also a specially named flagship series Grandioso. Even so, the K-01XD is already a very high-level CD/ SACD turntables, there are very few competitors on the market that have to be compared. The evolution of K-01XD this time is derived from Grandioso technology, which includes the new CD/SACD reading mechanical system VRDS-ATLAS and the new digital decoding circuit Master Sound Discrete DAC.
VRDS-ATLAS is Esoteric''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s very advanced turntable mechanism at this stage. It is decentralized from Grandioso P1X and K1X to its other models. K-03XD adopts the ATLAS 03 mechanism specially designed for it, and still has a steel bridge design, which can improve the rigidity and quality, and reduce the vibration that affects the sound quality. The overall structure of the turntable is changed to a lower, wide and thin design to lower the center of gravity, and the motor is moved from the top of the steel bridge in the past to below the turntable, which can greatly reduce vibration and reduce mechanical noise. The bottom of the VRDS-ATLAS mechanism is fixed with a 5mm thick steel base plate. Through the patented three-point support design, the vibration of the rotating mechanism can be effectively suppressed. The box has a double-layer structure, the lower layer is the power supply, and the upper layer is the main circuit. The isolation from each other can prevent magnetic leakage and vibration, and make the power wiring shorter.
The K-03XD has also greatly enhanced the power supply, equipped with a total of 4 large-capacity toroidal transformers, which supply power for the left and right channel DAC circuits, the laser reading mechanism, and the digital circuit. K-03XD also introduces the technology of Grandioso P1X / D1X, and uses a low feedback DC regulator with separate parts to control the feedback to a minimum. In addition, K-03XD is equipped with 26 filter capacitors with a total capacity of 650,000μF, can significantly improve the low frequency resolution.
The brand-new Master Sound Discrete DAC is designed and manufactured by Esoteric in-house. The left and right channels are processed by independent circuits. It does not use ready-made DAC chips. It uses FPGA with array resistors to complete digital processing and analog conversion. All digital signals and clocks pass through its own FPGA. After that, it is sent to the DAC for decoding and conversion into an analog signal, Esoteric’s patented Delta-Sigma (ΔΣ) The modulator supports the sampling frequency of 64-bit/512Fs. It processes DSD and PCM signals separately, supports up to DSD 22.5MHz and PCM 32bit/384kHz file input, the built-in FPGA up-conversion can be up to 768kHz, and provides PCM-to-DSD capability.
The support capability of MQA is also one of the reasons why this time is attracting attention. K-01XD is now not only an SACD/CD player, but also an MQA-CD player, which can directly read commercially available MQA-CDs. The MQA support can be turned on or off in the -01XD''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s directory setting menu, and it is also convenient for users to compare the final sound difference with or without MQA processing. This is a highlight of K-01XD. Although the number of MQA-CDs is not many at present, It is a new format and new features. In addition to reading MQA-CD, K-01XD can also fully decode MQA, and can transmit MQA digital files via USB, optical fiber, and coaxial input for K-01XD to decode. If the user has a Tidal network streaming service, You can enjoy a large number of MQA music files.
