The long awaited Luxman D-07X features the high-end Rohm BD34301EKV DAC chips as the $9000 more expensive D-10x as well as the LxDTM transport.
The two chips are used in a dual monaural configuration lie at the core of the digital circuitry that processes various digital media from discs, such as CDs and SACDs, to the latest high resolution audio files with exceptional quality. Over a USB input from a PC, Mac, NAS for audio, etc., the D-07X supports a wide range of format encoding up to PCM768kHz/32 bit and DSD22.4MHz. Bulk Pet transfer, which equalizes transmission load, can also be selected by using our dedicated driver software. Furthermore, for the popular high-quality format MQA (MQA-CDs and MQA file), which expands the field of optical discs, streaming USB, COAX, and optical. The clocking system is designed to support accurate digital signal processing and is equipped with two high-precision, low-jitter, ultra-low phase noise modules that reduce noise near the oscillation frequency to a minimum. There is also a built-in, 2-mode analog FIR filter that allows you to select your preferred sound quality when playing SACD or DSD files.
The new Luxman D-07X s a component that handles digital sources, high-precision signal reading by the drive mechanism and advanced digital signal processing are very important, but it goes without saying that the high performance analog output circuitry which determines the final audio quality is the most important factor in realizing that deep musical expression expected from high-end components designed by LUXMAN. The D-07X has a newly developed I/V conversion system that receives the differential outputs of the paired BD34301EKV DAC chips, operating in monaural mode, and feeds four discrete, perfectly matched amplifier modules. High-quality buffer circuitry lowers the impedance of the output signal. The unit powerfully drives any integrated amplifier or control amplifier that would be the next stage component. Out-of-audible-range filtering, which is essential for digital players, is performed in the buffer stage instead of having an independent LPF stage, enabling the reproduction of natural and smooth analog waveforms, resulting in higher clarity and more immediate sound quality.
The D-07X includes a large capacity power supply with a power transformer capacity that has been increased by 50% compared to our D-06u model. Large capacity filter capacitors and independent regulator blocks have been installed for each circuit to develop a highly stable overall power supply environment traditional to LUXMAN. Again, clean and stable power has been achieved.
The new FL display with excellent visibility that shines on the delicate panel of blaster white finish is equipped with a 4x zoom display mode that is easy to see even from a distance. When playing the MQA format, the decoding status (Studio: Blue, Authentic: Green, Renderer: Magenta) is displayed by a three-color LED indicator.
