Throughout the app, you’ll discover a comparatively intuitive interface that allows you to futz with tons of settings, select inputs, and stream audio by way of companies like Spotify, Tidal, Deezer, and others. You may add Favorites for fast entry to a big selection of native and world radio stations or play immediately from Spotify Join, AirPlay 2, Chromecast, or Bluetooth. It’s also possible to stream hi-res audio information from an area server at as much as 384 kHz/32-bit decision or DSD as much as 11.2 MHz.
The GX70’s unfold of connection choices is spectacular and consists of three digital inputs (two optical and one Coax), USB-B and USB-A, and good ol’ FM radio. Outputs embody a front-facing headphone output, stereo speaker outs, and a preamp output for connecting a second amp or a powered sub. So yeah, you received’t run out of the way to play anytime quickly.
If you happen to want a extra tactile technique of management than the cell app, the GX70’s long-wand distant harbors nearly all of vital features, although I want it included backlighting. You received’t want it for TV management, although, as your TV distant enables you to management energy and quantity when linked over HDMI ARC—simply ensure that to first regulate your TV’s audio output to PCM, or the amp will make horrible noises that would injury your audio system.
Elegant audio
Whereas the SU-GX70’s truckload of options understandably get the lion’s share of consideration, in terms of efficiency Technics has delivered a transparent and succesful amplifier behind all that flashy tech. With an environment friendly energy plant of 40 watts per channel for an 8-Ohm load, the amp shouldn’t have any hassle powering most speaker units, from bookshelves to towers.
I examined the GX70 with three totally different bookshelf pairs, together with the Bowers & Wilkins’ 606 S3 (8/10, WIRED Recommends), Focal Theva (9/10, WIRED Recommends), and Polk Legend L100. Throughout all three fashions, the Technics offered crisp and clear audio with wonderful definition, a exact and well-defined stereo picture, and spectacular stability throughout frequencies.
Coming from the Uniti Atom, which prices practically double what you’ll pay for the SU-GX70, I understandably needed to regulate my expectations. The Technics doesn’t provide the identical physique and dynamic sound within the midrange and bass, nor does it present a soundstage as expansive or dimensional because the one Naim’s black field delivers. There’s a motive the Uniti Atom is an audiophile favourite, however you’ll pay for that pleasure and get fewer inputs and settings into the cut price. That mentioned, the Technics’ sound profile can also be a departure from my different foremost setup, KEF’s LSX-powered bookshelves.
The trait that actually caught my consideration after I linked the SU-GX70 is its brighter and extra scientific supply. That was particularly noticeable with TV content material, the place the amp introduced a extra ahead tone and a few ramped-up sibilance, with “S” sounds seeming to leap out a bit extra readily in mild audio productions. I received used to the tighter tone over time, and the amp is an particularly good pairing with Focal’s easy and silky Theva audio system, which offer nice readability with out ever sounding sharp. The snappier B&W 606 S3 created a much less amicable partnership.
When connecting U-Flip’s Orbit Concept (9/10, WIRED Recommends) turntable (I’ll be auditioning a Technics SL-1500C-W subsequent, so keep tuned), I famous a drop in dimensionality and heat over the Naim system, however once more that’s to be anticipated at this worth, and I used to be impressed by how effectively the GX70 holds up for the cash. Albums like Elton John’s Tumbleweed Connection sound sparklingly clear, full with all of the creamy goodness of his piano and a powerful collage of twangy devices throughout the soundstage in songs like “Amoreena” and “The place to Now St. Peter?”
Whereas it’s necessary to choose the suitable speaker pairing, specifically these with smoother sound profiles from manufacturers like KEF or Focal, the SU-GX70 is a enjoyable and versatile system. Its candy mixture of clear and detailed sound and gobs of options and connection choices make it an attractive stereo centerpiece for budding audiophiles.
