Technics SU-G700M2 Here are what customers ask for most when considering this Amplifier; People frequently ask about the Technics SU-G700's digital amplification (specifically, that it's not a standard Class D but a full digital design), its lack of streaming features, and comparisons between the original and M2 (Mark II) versions. Other common questions concern its sound quality, such as whether the bass is overpowering or if the mid-range hardens under pressure, and how it performs with different speakers and sources, particularly regarding the built-in phono stage and headphone amplifier. Digital Amplification While the SU-G700’s size and weight makes it seem like a class-AB amplifier, it’s a true digital amplifier. Using Technics’ Jitter Elimination and Noise-shaping Optimization (JENO) circuitry, the SU-G700 operates entirely in the digital domain, from input stage to speaker terminals. Incoming PCM and DSD signals are converted to a pulse-width modulation (PWM) signal by the switching output stage, obviating the need for a traditional delta-sigma DAC. The JENO engine is a key component in the signal chain, using a battery-driven clock generator (instead of the main power supply, for maximum isolation and noise suppression), a sample-rate converter, and a PWM modulator. Volume control, too, is handled entirely in the digital domain. Combined with a bespoke, hybrid switch-mode power supply -- which, Technics argues, is superior to a traditional switching power supply thanks to its fixed switching frequency -- and a linear regulator to stabilize the output voltage, this circuit topology is ideal for digital sources. The discrete headphone amplifier, meanwhile, is a class-AA design that uses a pair of op-amps: one for voltage, one for current. The result - such perfection in digital leads to vanishingly low distortion, which means smooth, warm and natural. Lack of streaming features Yes, on purpose. Technics want you to choose your streaming platform. The are many options - see here Sound Quality Built like a hi-end Audiophile Amplifier. Quality is in the details LAPC is designed to optimize the amplifier's performance for different types of speakers by precisely calibrating the amplifier's gain and phase characteristics to match the specific load presented by the connected speakers, resulting in a more natural and spatial sound The SU-G700 features a robust double steel plate chassis that minimizes vibrations and external noise, ensuring a stable platform for the sensitive audio circuitry. Its three-section design isolates the power supply, power amplifier, and signal input/output sections, further reducing interference and enhancing audio clarity. The SU-G700 utilizes a newly developed low-distortion switching power supply that is designed to suppress fluctuations in switching frequency, which can negatively impact sound quality. Reviews of this amplifier have been ridiculously positive. A winner. Reviews Here is what Soundstage says about this amplifier: "But its sound - dynamic, visceral, highly resolving -- was exemplary, and a mere stone’s throw away from that of far more expensive gear. Nor did its resolving abilities come at the expense of midrange body or delicacy. As long as you don’t need a ton of power, the SU-G700 should be at the top of your list for an integrated amp at the $4000 price point. It’s an easy Reviewers’ Choice, and an early contender for Product of the Year". Hans Wetzelsoundstagenetwork.com "I had more fun with it than I’ve had with any other amp I’ve reviewed in the past two years. Its styling respects the Japanese company’s history while still looking cool -- especially those big, blue-tinted power meters. While its digital amplifier circuit is cutting-edge" Soundstage Access read the review deep dive video review - please allows 10secs to load video review #2 please allow 10 secs to load Technics wins Stereophile Award "Streaming from Qobuz and Tidal via Roon, KM was impressed by the Technics's D/A section, commenting that he "bathed in the G700M2's warm glow of good tone, ample soundstage, forward flow, and solid dynamics allied to copious low-end and detailed treble." He added that while the amplifier imbued files with a sense of warmth, it wasn't overly colored. He also liked the way in which the phono input was sufficiently transparent to reveal the differences between different pressings of the same album. "The G700M2 is a warm-blooded, even-keeled, dynamic, capable amplifier," he concluded. It offers "ample power, robust build, and good value."
