Inside the app, you’ll discover a comparatively intuitive interface that permits you to futz with tons of settings, select inputs, and stream audio through companies like Spotify, Tidal, Deezer, and others. You may add Favorites for fast entry to a big selection of native and international radio stations or play immediately from Spotify Join, AirPlay 2, Chromecast, or Bluetooth. You may as well 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 contains three digital inputs (two optical and one Coax), USB-B and USB-A, and good ol’ FM radio. Outputs embrace a front-facing headphone output, stereo speaker outs, and a preamp output for connecting a second amp or a powered sub. So yeah, you gained’t run out of how to play anytime quickly.
Should you favor a extra tactile technique of management than the cell app, the GX70’s long-wand distant harbors the vast majority of important features, although I want it included backlighting. You gained’t want it for TV management, although, as your TV distant allows you to management energy and quantity when linked over HDMI ARC—simply make certain to first alter your TV’s audio output to PCM, or the amp will make horrible noises that might harm your audio system.
Whereas the SU-GX70’s truckload of options understandably get the lion’s share of consideration, relating to 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 bother powering most speaker units, from bookshelves to towers.
I examined the GX70 with three completely 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 glorious definition, a exact and well-defined stereo picture, and spectacular steadiness throughout frequencies.
Coming from the Uniti Atom, which prices practically double what you’ll pay for the SU-GX70, I understandably needed to alter 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 discount. That mentioned, the Technics’ sound profile can be a departure from my different major setup, KEF’s LSX-powered bookshelves.
The trait that basically caught my consideration once 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 gentle audio productions. I obtained 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 give 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 Idea (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 nicely 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 essential to select the fitting speaker pairing, particularly 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.
