The Technics Grand Class SL-G700 Network Super Audio CD Player plays discs and streams high-res music
Audiophiles still love listening to music on disc, but this high-end SACD player can also stream tunes from any source on your network—including the internet.

Technics has a pricey new music maker that lets audiophiles who treasure tube amps and floor-standing tower speakers keep the analog faith and still embrace the best of today’s digital media.
Seen, but not heard in Technics’ Venetian suite at CES last week, the Technics SL-G700 Network Super Audio CD Player is defined as “a multi-digital player that covers most of the digital audio media available today—from traditional CD/SACD to the latest high-res and popular streaming services—and plays them all back in the highest possible quality.”
“Our audio engineers” (some on the job throughout the 20-year span when the Technics brand lay dormant, according to Technics’ business development manager Bill Voss) “were all thinking what to do, what was the reason to come back? What’s relevant, and what will other high-end audiophile companies eventually come up with? This product fits that mission perfectly.”
The goodies on the inside
The SL-G700 boasts “phenomenal build quality,” Voss said. “We’re on a mission to optimize the analog audio output for connected old-school gear.” He cited the SL-G700’s high-speed silent hybrid power supply, which has a discrete layout and meticulous tuning to realize a high signal-to-noise ratio, as well as the player’s isolated dual mono construction digital-to-analog circuitry, based on Asahi Kasei Microdevices AK4497 DACs.
A noise-isolating, battery-driven, ultra-low-jitter clock generator powers the digital audio signal processing, while a separate interference-eliminating D/A circuit is onboard just for headphone listening via a Class AA amplifier. Technics’ own processor—dubbed JENO (Jitter Elimination and Noise-shaping Optimization)—clicks on only when headphones are connected.
The networking side of the SL-G700 will pull in streaming audio from Tidal—including the “Masters” selections encoded in MQA format—in addition to Spotify, Deezer, and the thousands of free internet radio stations aggregated by the V-Tuner streaming service. More streaming services will likely be added before the player launches. All will be accessible within the Technics Audio Center app that Voss couldn’t show me “because it’s still under construction.”
The box makes wireless connections via Wi-Fi (dual-band 802.11ac), Bluetooth, Chromecast, and Apple Airplay 2. On the backside, your hard-wired connection options include both balanced (XLR) stereo outputs and variable-level RCA analog audio outputs. You’ll also get digital audio outputs (optical and coaxial), of course, but Technics also provides the same as inputs: “…good for things like connecting your old 300-disc CD changer and listening in a fresh way through this processor,” Voss said.
If you’re the type who buys downloadable music and stores it on a NAS box, Technics’ player will “find the files from the music server over DLNA on the Wi-Fi network, identify the music and play it,” Voss said. You’re not limited to Wi-Fi, of course, there’s a 100Mbps ethernet interface on the back panel as well.
Not Technics’ first rodeo
To be sure, Technics has fielded other network players and network-integrated amps (not to mention turntables) since Panasonic resurrected the brand in 2015. But this will be its first product to handle SACDs, which are encoded in Direct Stream Digital (DSD) format, in addition to Red Book Audio CDs. You might recall that Panasonic was one of the primary backers of DVD-Audio, which Voss believes was undone in part by its video-centric operating system. “You needed a TV monitor to operate the disc functions,” Voss said, “you couldn’t find the track you wanted without a screen, very frustrating.”
When the SL-G700 is in SACD/CD playback mode, all power supplies—except those for the circuit blocks necessary for disc playback—are shut off, improving the quality of the stereo-only sound output. Yes, you read that right. Technics has decided that high-end audio guys don’t give a hoot about the multi-channel mixes that come on many SACDs. “Two-channel high-res is all they want,” Voss said.
Technics is also touting its High-Res Remaster processing, which the company says will expand the bandwidth and bit depth of any source material. Music encoded in 44.1kHz/16-bit resolution—and even lossy tracks like MP3s—it says can be revved up to high-res 192kHz/32-bit resolution. Color us skeptical on that claim. We haven’t heard this player, but no one can create something from nothing. If the data isn’t in there in the first place, where exactly is it coming from?
That aside, we heard plenty to like about Technics’ new player. And by now, you’re probably wondering what it’s going to cost when it comes to market later this year. “$3,500 is our target,” said Voss. And if you want to pair it with its most logical soul mate—the aesthetically matched Grand Class SU-G700 integrated stereo amplifier that came out in 2017—be prepared to toss another $2,500 on the counter.
