Technics amplifier

Technics displayed their Reference Series product line at CES 2017. While the New York Times recently focused on the introduction of the company's SL-1200G coreless-motor direct-drive turntable ($4,000), my interest focused on Technics' 188-lb, $17,000 SE-R1 digital amplifier, which I heard powering their SB-R1 3.5-way floorstanding speakers. Bill Voss, Technics' Business Development Manager, explained that the SE-R1 is rated at 300Wpc into 4 ohms (the load impedance of the SB-R1 speakers). The amplifier uses a pulse-width modulation circuit, a high-precision sample-rate converter for suppressing jitter, and a gallium nitride FET driver with very low output impedance to drive loudspeakers. In addition, the amplifier employs their proprietary load adaptive phase calibration (LAPC) to measure the amplifier's phase characteristics with each speaker it drives to achieve a flatter frequency response. Although the SE-R1's huge twin output meters and beautiful anodized-aluminum finish were visually distracting, the marketing of a class-D amplifier as a separate high-end component was important. This amplifier delivered some of the best reproduced sound at CES 2017. I persuaded Bill Voss to rip the contents of my copy of Rutter's Requiem to his media server's solid-state drive. The broad and deep soundstage, imaging, upper midrange detail, and bass extension were thrilling during the system's rendition of "Lord, make me an instrument of thy peace" and "Pie Jesu." I appreciated the...

The Reference Class Stereo Power Amplifier sets a new high performance standard for digital amplifiers by employing state-of-the-art components and innovative technologies. • JENO Engine(Jitter Elimination and Noise-shaping Optimization) • GaN-FET Driver • LAPC (Load Adaptive Phase Calibration) • Technics Digital Link • High-speed Silent Linear Power Supply • Battery Driven Clock Generator Download Catalog And Full Specs Jitter is a major cause of distortion in digital systems, and is caused by mis-timing in the master clocks used in digital-to-analog conversion. To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with a newly-developed and original high-precision PWM (Pulse Width Modulation) conversion circuit, optimizing the noise-shaping speed, the degree and requantization number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These new technologies enable new Technics digital amplifier designs to reproduce the natural and delicate nuances of music.

The SU-G700M2 is an integrated amplifier combining a selection of analogue and digital inputs in such a way to be most of a complete system when a pair of speakers is added. This is par for the course in 2022; indeed we’ll be looking a fair few more such amps in the months to come. The ‘M2’ bit of the name is important too. This is not a clean sheet design but an update to the existing SU-G700 which has been quietly plugging away in the range for a few years before this. The M2 brings a series of revisions and tweaks to the basic design and the origin point of some of this thinking is a device we’ve tested before. The You can have three SU-G700M2’s for the price of an R1000 though and, on first inspection, a fair bit of the ideas, thinking and features of the bigger amp are present here too. Of course, something else present at the same sort of price is a selection of great rivals so we need to ask, has Technics squeezed the proverbial quart into a pint pot and is the result good enough to challenge some of the amps we’ve seen so far? Time to fire it up and see what it does. In keeping with the SU-R1000, the SU-G700M2 does not kick its spec sheet off with a power figure you could jump start a planet with. Technics quotes a reasonable but entirely unremarkable 70 watts into eight ohms which doubles neatly into four. More power is available for similar money but equally, most speakers and most rooms don’t require anything like as much power to be driven to room filling level...

When I reviewed Technics's SU-R1000 integrated amplifier for the What's more, joined to my reference system, the SU-R1000 upended my preconceived notions of what switching amplification sounds like and enlightened me about the sonic possibilities of those other innovations: Technics's super-speedy GaN FET switching transistors; JENO Engine jitter reduction; ADCT (Active Distortion Cancelling Technology, footnote 1); Intelligent Phono EQ; LAPC (Load Adaptive Phase Calibration, footnote 2); and the SU-R1000's practice of digitizing every signal that entered and departed its steel-encased frame. And then there was the SU-R1000's low noisefloor, credited to its Advanced Speed Silent Power Supply (footnote 3), which undoubtedly was at least partly responsible for the Reference Technics amplifier's surprising resolution. I wasn't alone in my praise for the SU-R1000. Technical Editor John Atkinson found some things to crow about when measuring the amp, concluding, "As with the Technics SU-R1000's line-level analog inputs, this amplifier's digital and phono inputs offered excellent measured performance." I mentioned class-D, but Technics maintains that the SU-R1000 isn't a class-D amp. Most other class-D amplifier manufacturers claim, with justification, that " So when Bill Voss, Technics's US business development manager, offered Editor Jim Austin and me a crack at the SU-R1000's less-expensive new sibling, I was all ears, limbs akimbo in anticipation. The SU-G700M2 integrated am...
