Marantz SA-10 - Black - Gold

Description

From the unique disc transport designed for this player all the way through to a complete rethink of the way digital audio data is converted into analog signals, the SA-10 is a 'clean sheet' design, the result of painstaking research and development and extensive listening in Marantz's custom-built listening facilities. That's symptomatic of the way Marantz has always done things: while it always aims for the most elegant engineering solution, the listening test is always the final arbiter.
 

CDs, SA-CDs and beyond

However, the SA-10 goes so much further than just disc playback: it's also a fully-functional digital-to-analog converter for music stored on a home computer, as well as having conventional digital inputs for existing source components. Those conventional inputs - optical and coaxial - can handle files at up to 192kHz/24bit, but in addition the player's digital input section includes a USB-B asynchronous input for the direct connection of a computer, and this is compatible with PCM and DXD music files at up to 384kHz/32bit, as well as DSD2.8MHz, DSD5.6MHz and DSD11.2MHz.

Marantz Musical Mastering: MMM-Stream and MMM-Conversion

DSD is at the heart of the way the SA-10 handles digital audio: PCM and DXD inputs are all upconverted to DSD at 11.2MHz using the proprietary MMM-Stream converter within the player, and then the high-frequency signal produced is processed by the unique MMM-Conversion stage, used in place of a conventional DAC, to produce the analog output. The MMM-Stream section of the process replaces the oversampling filters normally used in digital to analog conversion, and allows the implementation of the Marantz Musical Mastering filtering. These filters - one providing a slow roll-off and very short impulse response, the other offering the option of a medium roll-off with short pre-ringing and longer post-ringing - are essentially the same as those found in the Marantz SA-11 disc player and NA-11 network music player, but here they're implemented at a much higher oversampling rate, thanks to that upconversion to DSD11.2. In fact, two system clocks are used, to ensure the most accurate upconversion of the incoming signal, whether its from disc or the digital inputs: the 44.1kHz of CD, and its multiples - 88.2kHz, 176.4kHz and so on - are upsampled to 11.2896MHz, while 48kHz and its multiples are taken up to 12.288MHz. This is done for maximum precision, and to avoid any need for sample rate conversion of the kind were the system to have to convert, say, 192kHz audio to DSD12.2MHz. In addition, all of this conversion is now done in Digital Signal Processing with 32-bit floating-point precision, rather than the 24-bit integer method used in such systems in the past.

Built to perform

Like the partnering PM-10 integrated amplifier, the SA-10 is constructed to the highest possible standards, with a double-layered copper-plated chassis for excellent rejection of mechanical and electrical interference, and casework constructed from thick non-magnetic aluminum panels and 5 mm thick top lid. Both products also sit on aluminum machining feet.
