"Five Stars" – What Hi-fi? Magazine"A Beautifully Constructed Soundstage"The SA-10 is an exceptional player of both CD and SACD discs. It also excels with high-resolution music stored on computer-burned discs, as well as being a high-end digital to analog converter for computer-stored music. The 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, it had the first high-end performance-tuned CD player, and that expertise has continued to be developed over more than 30 years. The SA-10 is designed to sets new standards, whether with music on disc or content streamed from a computer, and to become the new reference in digital audio. From the unique new disc transport 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. It's 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 Marantz always aims for the most elegant engineering solution, the listening test is always the final arbiter. "One of the Finest Disc Players We’ve Come Across"England's What Hi-fi? magazine award the SA-10 it's top rating of Five Stars. According to What Hi-fi?, "We’re in no doubt that the Marantz SA-10 is a brilliant digital source component and one of the finest disc players we’ve come across… It’s very well made and has the kind of unfussy disposition that allows it to sound right at home across a wide range of systems. Highly recommended." "The Vocals Were Lifted with Uncanny Precision""It was the vocal performance in the [Peter] Gabriel track — an analog recording from the ’80s, rather than a Hi-Res digital file from 2016, it turned out — and in KD Lang’s Hallelujah, which really emphasized the Series 10 beautifully constructed soundstage," reports Andy Boxhall in his June 14, 2016 joint review of the Marantz SA-10 disc player and Marantz M-10 integrated amplifier at Digitaltrends.com. "The vocals were lifted, center stage, with uncanny precision. Not only was the illusion of the singers being in the room expertly cast, but they were elevated up on a stage, encouraging you to raise your head to 'see' them, rather than look down, eyes closed, or straight ahead at the speakers." It Starts with the DiscWhether you are playing an SA-CD, CD, or a data disc containing music, it's vital that your 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 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 this new mechanism promise the very best sound quality from conventional CD and SA-CD discs, but its extended ability with the playback of music files stored on DVD-ROM discs also makes it possible for users to create their own high-resolution audio compilation discs using a computer DVD burner. The SA-10 can play FLAC files from 44.1kHz to 192kHz at up to 24-bit resolution, and DSD2.8MHz and DSD 5.6MHz, 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. CDs, SACDs, and BeyondThe SA-10 goes so much further than 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 up to 192 kHz/24-bit. Also, 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. That means the 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 player is entirely futureproof. What's more, the digital 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. More Than Just a DACCD players (and amplifiers) with built-in DACs usable for computer audio are nothing new, and neither is DSD capability on such devices. The Marantz range already has several CD/SA-CD models so equipped. However, the SA-10 takes things further, just as it features an all-new disc transport mechanism. The digital-to-analog conversion has 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 upconversion to take advantage of this simple, but elegant solution. Marantz Musical Mastering: MMM-Stream and MMM-ConversionDSD is at the heart of the way the SA-10 handles digital audio. PCM and DXD inputs are 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. 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 player's output stage. In-house Marantz InnovationSo why develop all this in-house? The Marantz engineering team says that, as ever, extensive listening sessions gave the reasons. The team 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, Marantz had to do the conversion themselves. The same thinking informed the design of the DSD-to-analog 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 player is optimized. 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. Built to PerformThe 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 5mm thick top lid. It sits on machined aluminum feet.
"The Marantz SA-10 is a superb and perfectly reliable DAC, easily handling very high-resolution digital files and delivering sound quality at a level only equaled by the original medium. With outstanding build quality, simple user interface, and perfect compatibility with any normal input signal, this is a component that does its job so well that an “upgrade” seems entirely superfluous. The Marantz SA-10 is a reference-level component that will make its owner happy for many years." - 10 Audio, November 21, 2020 "Five Stars" – What Hi-fi?
