Description

Technics SU-G700M2 Integrated Amplifier Dazzles with Magnificent Sound, Soaring Far Beyond Similar Amps, Even Those in Higher Price Classes

The Technics SU-G700M2 Integrated Amplifier delivers spectacular sound that evokes the experience of sitting in the ninth row at a concert. When you consider its price tag, you quickly realize this is one of the best values on the market, offering sonic performance that not only matches but actually surpasses that of much pricier integrated amps.

In order to faithfully transmit the massive amount of audio data sent to the speakers without loss, the SU-G700M2 power amp section uses full digital amplification employing the JENO Engine, based on the design concept of reference systems. In order to solve the issue of sound quality degradation due to jitter, which poses problems for conventional digital amplifiers, the SU-G700M2 has an original jitter reduction circuit that eliminates jitter over the entire audible frequency range.

Also, a unique, high-precision PWM (Pulse Width Modulation) conversion circuit is used for PWM conversion, which is important for sound quality. By optimizing items such as the noise-shaping speed, degree, and quantization number through our unique expertise, data even in the wide dynamic range contained in high-resolution sound sources is converted to PWM signals without loss. These technologies provide reproduction of natural and finely detailed sound, enabling perception even of delicate music nuances.

Speaker impedance changes with each frequency and a power amplifier is required to drive speakers without being affected by the speaker's characteristics. However, conventional digital amplifiers are connected to speakers through a low-pass filter at the output stage, so they are even more strongly affected by the speaker impedance characteristics. Also, although the amplitude characteristics of conventional amplifiers due to negative feedback were improved, the phase characteristics could not be enhanced. We thus developed a speaker impedance adaptive optimization algorithm that performs correction to the ideal impulse response through digital signal processing by measuring the frequency amplitude-phase characteristics of the amplifier with the speakers connected. This new technique enables flattening the frequency characteristics of amplitude and phase, which had previously not been achieved by amplifiers, as well as delivering a sound with rich spatial expression.

The power supply technology incorporated in the reference-class model SU-R1000 has been employed for improved speaker drive power and a greater feel of energy. The switching frequency has been increased from the conventional 100kHz band to the 400kHz band to ensure stable supply of voltage and current and to reduce adverse effects of modulation noise on the audio quality. The device is equipped with the same GaN FET and SiC SBD as those mounted in the SU-R1000 to deliver maximum performance from the high-speed switching power supply system. What's more, a Super Low Noise Regulator is provided in the later stage. It prevents the decrease of regulation due to fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a low-noise and high-response power supply that maximizes the performance of the digital amplifier.

In integrated amplifiers there are a variety of circuits, including circuits that handle the micro-signals of inputs and those that handle a large current, such as output circuits and power-supply circuits. The SU-G700M2 uses a three-section construction with partitions installed between the circuit blocks according to the signal level handled. This eliminates interference between circuit blocks, thus achieving clear sound quality. In addition to the three-section construction, the SU-G700M2 comes with a bottom chassis featuring a two-layer construction with 1.2-mm-thick and 2-mm-thick steel plates, a top panel made of a 1.6-mm-thick steel plate and a 7-mm-thick aluminum front panel for improved vibration damping.

Like all Music Direct products, it comes with the 100% Music Direct Satisfaction Guarantee.

"Offering ample power, robust build, and good value, the Technics SU-G700M2 Grand Class integrated amplifier sounded great in my reference system. If [its price] is in your comfort zone, the G700M2 offers exceptional bang for your hard-earned bucks."
—Ken Micallef, Stereophile

"The concert hall sounded vast, and the music bounded along in a hurry. Dynamics on crescendos were excellent for an amplifier of this price, too, not least because the MC stage is super-quiet.... Such is the quality of the new SU-G700 Mk2 that I often forgot I was listening to a mid-price integrated amplifier — as opposed to my normal high-end pre/power.... [It offers] power, punch, scale, drive, engagement, and excitement, yet with little loss of smoothness or civility.... [It's] an essential product to audition if you're in the market for an amplifier at or near this price...."
—David Price, StereoNET, Applause Award

"The bass here provides power, but also has a sense of proportion and a sense of stability—even, well, poise—so bass always sounds part of the musical output, instead of being outside of it. The mids are smooth, but also bring along with it an airy presentation, so the soundstage always has a relatively spacious feel to it. Music from the G700 sounds like the sun is adorning it with an early-morning glow.... Both upper-mids and treble present you with detail that's easily recognizable: You never have that horrible moment where you're asking yourself, 'Is that a violin or is it a cello?'... This is sonic precision of high quality."
—Paul Rigby, The Audiophile Man (YouTube), Groovy Award review

"Clear, lucid, with fine dynamics and even top-to-bottom frequency response, vinyl played through the G700M2 left me wanting nothing. Typically, when I evaluate an amplifier's onboard phono stage, I can't wait to return to my separates. With the G700M2, that thought never crossed my mind. I was having too much fun playing records and comparing pressings to bother."
—Ken Micallef, Stereophile

"Technics has made all the right choices, focusing on the sound experience ... thus creating a very high-value-for-money amplifier that will make your foot tap.... With the G700M2, Technics proves that fully digital technology, done right, has so many advantages. In short, there's a new king [in this price class], with some real improvements over the previous, already-great-sounding [model]."

"[This] amplifier sounds positively cultured. It's as balanced as a tightrope walker; as friendly as a Labrador dog. It's as relaxed as a Brian Eno fan. It's as neutral as Switzerland."
—Paul Rigby, The Audiophile Man (YouTube), Groovy Award review

Premium Phono MC Input

The SU-G700M2 offers a high-quality, carefully engineered phono MC input. This phono input achieves low noise by using a differential parallel connection configuration of a first-stage, low-noise FET. In addition, four-level gain adjustment enables selection of the best gain according to the cartridge output. This enables optimal playback of high-grade analog recorded sound sources, tailored to your specific listening environment.

Superb Headphone Amplifier

The SU-G700M2 uses a Class AA headphone amplifier with separate amplifier circuits for voltage amplification and current amplification of the audio signal. The voltage is amplified by a high-grade operational amplifier. The current is amplified by an operational amplifier with high current-supply capability, and the high-grade PWM signal output from the JENO Engine is converted to analog with high precision, thus enabling headphones to be ideally driven. This makes it possible to reproduce music with low distortion and a wide frequency range, no matter what the load impedance of the headphones is.
