Technics Grand Class SL-G700M2 Digital Audio Player Released

Technics' SL-G700M2 network/Super Audio CD player builds on its Applause Award-winning predecessor with a host of performance and sound improvements.

The Technics SL-G700M2 multi-digital player possesses a high-performance, dual monaural digital-to-analogue converter, SACD player, and supports hi-res streaming services and many digital audio media, including full decoding of MQA files and MQA-CDs. In addition, various other high-resolution formats are also supported, including WAV/AIFF up to 384 kHz/32 bit, FLAC/ALAC up to 384 kHz/24 bit, and DSD up to 11.2 MHz file playback.

The SL-G700M2 is divided into four sections inside the chassis, with the power supply, digital interface, analogue circuitry and disc drive sections being independent of the other. This suppresses mutual interference between circuits and reduces sound quality degradation. In addition, the disc drive adopts a three-layer chassis configuration, vibration-damping, and quiet construction, including a disc tray made of die-cast aluminium said to ensure high-precision disc playback.

The exterior features a hairline-finished 7mm-thick aluminium front panel and 3mm-thick aluminium side panels.

Technics' goal for its next-gen products has been to achieve phase alignment and ideal impulse response – essential characteristics for faithful music reproduction with an accurate sound stage.

The SL-G700M2's High Precision Coherent DAC converts digital values to analogue signals before outputting them to an amplifier. It comprises three elements: coherent processing, a high-performance DAC in dual monaural configuration, and a proprietary discrete amplifier circuit. Technics states that this technology improves the reproducibility of impulse signals by minimising amplitude and phase deviations that occur throughout the D/A conversion process for signals up to 192 kHz PCM using proprietary digital signal processing. However, DSD signals such as Super Audio CD are input directly to the DAC without performing this processing. The result, we are told, is an increase in the purity of the sound and a more precise sound image overall.

The SL-G700M2 boasts the new dual ESS ES9026PRO, which, through the symmetrical placement of one L/R unit on each side of the device, is capable of independent transmission, reducing mutual interference.

The filter circuit after the D/A conversion uses an amplifier circuit with a unique discrete configuration instead of an operational amplifier IC. According to the manufacturer, this realises even higher responsiveness and S/N, reproducing even the most subtle sounds.

Digital audio players that handle small signals require thorough noise suppression because even the slightest noise can significantly affect sound quality. Therefore, the SL-G700M2 is equipped with a Multi-Stage Silent Power Supply, which mitigates noise in three stages.

Firstly, a high-speed switching power supply of approximately 300 kHz as found in the analogue circuits of the Technics SU-R1000 reference-class integrated amplifier. Increasing the switching frequency reduces noise interference on the music playback. Next, a dedicated power supply unit combined with the original stabilised power supply circuit provides power with low noise. Apparently, the discrete circuit structure does not use any general-purpose ICs. Finally, current injection active noise cancelling. This newly developed technology removes unwanted noise components by applying an inverse phase current to the detected noise. More effective current noise rejection can be achieved by using the push/pull method in combination with conventional noise rejection.

Furthermore, the SL-G700M2 sports a Pure Disc Playback mode that shuts off all circuit blocks except those required for Super Audio CD/CD playback, reducing internal noise and boosting sound quality.

Technics SL-G700M2

The SL-G700M2 supports Google Chromecast, as well as Apple AirPlay 2. Wi-Fi and Bluetooth wireless connections. The player is also equipped with a USB-B port allowing for a constant connection to a network audio server or PC for playback of high-resolution sound from the connected device.

The Technics SL-G700M2 is available from late-January 2023 and priced at $5,499 RRP.

    applause awards

    Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.

    Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.

    The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.

    We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
