Marantz SA-10 CD Player
The Marantz SA-10 features an all new SACD-M3 transport mechanism for CD, Super Audio CD and more
“Quote from Rainer Finck, Marantz’s SA-10 senior electronics engineer”
“As I was one of the Philips engineers way back in the late 80s, and worked on the company’s Bitstream converters – the last one was the DAC-7 – we could draw on all this knowledge to build our own bitstream converter for the Marantz SA-10. The output from the MMM-Conversion process is, in effect, already an analogue signal, being a very high-frequency stream of single pulses. With all the hard digital work done, this stream needs nothing more than a very high-quality low-pass filter to deliver the purest possible analogue audio output. For all its apparent complexity, this is actually a very simple, very elegant solution to digital processing – and it’s unique to the Marantz SA-10. That’s why we say it’s the first player/USB converter without a DAC – it doesn’t need one!”
Rather than down-converting ultra-high-resolution files to suit a conventional digital to analogue converter, the Marantz SA-10 upconverts everything to DSD256 (Marantz Musical Mastering – Conversion), which four times the SACD standard. Two filter settings to allow the listener to shape the sound.
The Marantz Musical Mastering package (MMM-Stream) then preps this DSD256 signal for analogue output to an amplifier. Based on technology going all the way back to early days of Bitstream conversion, this enables an ultra-simple conversion process.

The new Marantz SA-10 is the latest model in a range of high-end players stretching all the way back to the dawn of CD: in the original CD-63, launched in 1983, The Marantz SA-10 has the high-end performance-tuned CD player, and that expertise has continued to be developed over more than 30 years. The Marantz SA-10 is designed to set new standards, whether with music on disc or content streamed from a computer, and to become the New Reference in digital audio.
To achieve that, the Marantz SA-10 is a completely new design, drawing on all that experience in making great-sounding players but with virtually every part redesigned. That involved both innovation and some unique thinking, all in the cause of getting the best possible performance across a wide range of digital audio formats. The new model Marantz SA-10 is an exceptional player of both CD and SACD discs, but can also play high-resolution music stored on computer-burned discs, as well as being a high-end digital to analogue converter for computer-stored music.
From the unique new disc transport designed for this player all the way through to a complete rethink of the way digital audio data is converted into analogue signals, the Marantz 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 and especially now with the Marantz SA-10: while it always aims for the most elegant engineering solution, the listening test is always the final arbiter. It’s all to do with that simple phrase running through the heart of everything the company does: ‘Because Music Matters’.
|Whether playing SA-CD or CD, or data discs containing music on the Marantz SA-10 it’s vital that any player retrieves the information as accurately as possible: unlike a computer reading a disc for ripping, there’s no time for repeated re-scans when playing music – it happens in real time, so the disc transport needs to get things right first time.|
Many modern CD and SACD players use computer-style DVD or ‘universal’ disc drives, simply because it’s increasingly difficult for manufacturers to source dedicated ‘music drives’, purely designed for SACD/CD playback.
The Marantz solution? If you can’t buy it off the shelf, design it and have it made: at the heart of the Marantz SA-10 is an all-new SACD-M3 transport mechanism, engineered solely for the best possible performance when playing SA-CDs, CDs and music stored on data discs.
Not only does the Marantz SA-10 have a new mechanism, it promises the very best sound quality from conventional CD and SA-CD discs, its extended ability with the playback of music files stored on DVD-ROM discs makes it possible for users to create their own high-resolution audio compilation discs using a computer DVD burner. The Marantz SA-10 can play FLAC files from 32kHz to 192kHz at up to 24-bit resolution, and DSD64 and DSD128, well as ALAC (Apple Lossless), AIFF and MP3 files. That means making and playing hi-res disc compilations is now just as simple as it’s always been to make such discs in CD quality.
However, the Marantz SA-10 goes so much further than just disc playback: it’s also a fully-functional digital-to-analogue 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 Marantz SA-10 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 DSD64, DSD128 and DSD256.
That means the Marantz SA-10 is not only equipped to handle all the commonly-available high-resolution audio formats now sold by online retailers, but also the ultra-high-resolution files becoming available from a number of specialist labels and outlets. In other words, the new Marantz SA-10 is entirely future proof.
What’s more, the Marantz SA-10 input section is completely isolated, to avoid any electrical noise from connected components – a particular problem when computers are used as a source – from finding its way into the signal-path.
CD players (and indeed amplifiers) with built-in DACs usable for computer audio are nothing new, and neither is DSD capability on such devices. Indeed, the Marantz range already has several CD/SA-CD models so equipped.
However, the Marantz SA-10 takes things further – just as it features an all-new disc transport mechanism, so the digital to analogue conversion has also been subject to a radical rethink, taking full advantage of the 1-bit conversion technology found in past flagship Marantz players, and incorporating brand-new filtering and up-conversion to take advantage of this simple, but elegant solution.
Marantz Musical Mastering is found in the Marantz SA-10
MMM-Stream and MMM-Conversion
|DSD is at the heart of the way the Marantz 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 analogue output.|
The MMM-Stream section of the process replaces the oversampling filters normally used in digital to analogue conversion, and allows the implementation of the Marantz Musical Mastering filtering. These filters in the Marantz SA-10, 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 in the Marantz SA-10 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 11.2896kHz, while 48kHz and its multiples are taken up to 12.288kHz. This is done in the Marantz SA-10 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 DSD11.2.
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.
Combining this with the reduction to a 1-bit signal straight after the oversampling filter and Sigma Delta Modulation allows a pure DSD-standard signal to be passed to the conversion section in the form of a very high-frequency stream of pulses, requiring only a very high-quality low-pass filter to remove all the superfluous high frequencies and pass the purest possible audio to the Marantz SA-10 output stage.
So why develop all this in-house? The Marantz engineering team says that, as ever, extensive listening sessions gave the reasons: ‘We found big sound quality differences when PCM signals got converted to DSD outside of a conventional DAC and then fed to the DSD input of the conventional DAC. The conclusion of our finding was that for best sound quality we have to do the conversion ourselves.
“This experience led us to evaluate all kind of SDM structures and optimise the Marantz SA-10 to achieve the best sound quality.”
The same thinking informed the design of the DSD-to-analogue filter itself, which feeds into the familiar Marantz HDAM (Hyper Dynamic Amplifier Modules) in the output stage, here used in dual-differential configuration for optimal sound quality.
In the same way, even the headphone output on the Marantz SA-10 is optimised: like the HDAMs, it’s built entirely from discrete components, rather than using simpler ‘amp on a chip’ technology, for the very best sound quality.
The Marantz SA-10 is built to perform
Like the partnering Marantz PM-10 integrated amplifier, the Marantz 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 aluminium panels and 5mm thick top lid. Both products also sit on aluminium die-cast feet.
That may all seem very complex, as well as making it clear just how much work has gone into the design of this player, but in essence at the heart of the Marantz SA-10 is a digital-to-analogue solution that’s as elegant as it is innovative, and developed by the Marantz engineering team for one very simple reason:
‘Because Music Matters’
below is a quote by Jason Kennedy
Marantz SA-10 & PM-10
“Ken Ishiwata is a bona fide hi-fi guru, he’s got the look, the clothes and the underground lair, I mean listening room, to die for. In an unassuming office building in Eindhoven, Holland, Ishiwata has created one of the best sounding rooms in the world (see more here and here). This is where he refines and tunes Marantz electronics not least the range topping models like the new Marantz SA-10 SACD/CD player and DAC and its partnering amplifier the Marantz PM-10. These two pieces do not look like your typical high end electronics because the design and build is to a standard that can’t achieved with small batch manufacture. In some ways they are perhaps too slick for certain sectors of the market, if you like Boulder, Krell or D’Agostino you might find the Marantz SA-10 / PM-10 series a little too clean cut. If however you realise the benefits of Japanese build quality and the soundsmithing skills of the man in Eindhoven, they will certainly appeal.
Oh, and they weigh as much as anything from Europe or the US. Don’t be fooled by the quality of execution, these are both borderline back breakers. Not least the Marantz SA-10 which must be the heaviest digital source component that I’ve had the displeasure of shifting around for ages. But it’s worth the effort for these are exceptionally refined and revealing components, the overall impression they give is of tube liquidity with transistor back-up, proper iron fist/velvet glove stuff. The amplifier in particular makes most of the alternatives sound a bit crude and grainy.”
