Impressive Technics SU-G700 M2 Stereo Amplifier

The Technics SU-G700 M2 integrated stereo amplifier is a high-quality audio device designed to provide excellent performance and reduce noise interference to enhance audio clarity. It is a typical Japanese large-format model, featuring a metal-based, sturdy construction with useful commands on its remote control, such as a mute button, dimmer switch for VUs (Volume Units), and a menu button for adjusting various internal settings.

The internal design of the amplifier incorporates several key features to ensure optimal audio quality. The JENO Engine (Jitter Elimination and Noise-Shaping Optimisation) is implemented to eliminate jitter and distortion, resulting in more accurate sound reproduction. Additionally, LAPC (Load Adaptive Phase Calibration) is used as a speaker optimization app to further enhance audio performance.

To reduce noise interference, the amplifier’s internal components are carefully partitioned, and extra damping is achieved through a two-layer construction with 1.2mm-thick and 2mm-thick steel plates, as well as a 7mm-thick aluminum front panel. This design minimizes the impact of mechanical vibrations and electromagnetic noise.

The SU-G700M2’s power supply is also designed with noise reduction in mind. The switching frequency has been increased to 400kHz, increasing stability, and a low-noise regulator on the circuit board further contributes to clean power delivery.

Furthermore, the amplifier incorporates power conditioners with non-magnetic carbon film resistors and high-quality ruby mica capacitors for the PC input terminals, ensuring high performance and low noise.

The price of the Technics SU-G700 M2 integrated amplifier is listed at £2,199, indicating it is a premium product offering high-end audio capabilities.

The Technics SU-G700 M2 has digital and analog inputs, making it perfect for all of your music equipment. Utilize the optical and coaxial digital inputs to connect your network streamer, CD, and TV. There is a USB-B for your PC or Mac’s computer audio. The MM/MC phono stage does a good job of supporting vinyl.
Reference-level audio technology The SU-G700 provides very low distortion and very well optimized sound quality thanks to remarkable Technics audio technologies like JENO and LAPC.

The speaker performance of your speakers is optimized by the LAPC algorithm. Better focus, richness, and definition are produced by flattening the amplitude and phase-frequency response via digital signal processing.
High-resolution digital signals are delivered by JENO without any distortion being added between the input stage and speaker output. By creating this unique jitter-reduction circuit, Technics has avoided the sound quality decrease brought on by jitter that is typical of standard digital amplifiers. Regardless of the audio source, less jitter results in a smoother, more harmonized sound.
Technics has a large amount of experience using battery power for amplification. Using batteries instead of direct mains power is said to result in a cleaner, less distorted power source. The SU-G700 uses the technology to increase the accuracy of the digital clock, which improves the definition of the sound.Technics SU-G700M2

The Technics SU-G700’s Load Adaptive Phase Calibration (LAPC) circuit, which helps in optimizing the amplifiers output characteristic to match whichever speakers are connected for the best signal transfer, is one of the device’s most intriguing features. The speaker sensitivity of Class-D amplifiers is well known, and anything offering a reasonably complex load at the speaker terminals doesn’t always yield the best results. similar to that of an amplifier using SET tubes. The Technics SU-G700 M2 does not have this issue at all because to Technics’ unique design, and it readily drove all of the speakers we had available.

 

A 70 wpc (into 8 ohms / 140 into 4 ohms) amplifier is placed in the small, stylish, and straightforward SU-G700s housing, but digital is implemented in an interesting way. Since this is a fully digital amplifier, no digital to analog conversion is really performed until the final output stage to the loudspeakers; up until that point, all digital signals (PCM/PWM) stay digital. As a result, no DAC is performed up until that point. This is how Technics’ digital amplifier differs from other designs, yet you still get the advantages of the better digital processing that a DAC would have provided because the entire system uses a 32/384 digital amplifier process.

The finest details of music are preserved because circuitry processing micro-signals are isolated from those handling large currents.  Photo: TechnicsTechnics SU-G700M2

The Technics SU-G700 M2 is impressively presented, and despite being manufactured in Malaysia, it showcases a high level of finish that is almost on par with Japanese high-end amplifiers. Its user interface feels remarkably smooth and offers a more luxurious experience compared to European amplifiers in a similar price range. The front panel design is elegantly simple, featuring integrated power meters with switchable illumination, an input selector, volume controls with a sleek action, and a small OLED function display that adds a nice touch. It’s worth noting that accessing the submenus requires the included remote control, so it’s essential not to misplace it. Additionally, the front panel includes a headphone socket with a quality Class AA headphone amplifier provided by Technics.

The SU-G700 mk2’s exceptional quality often made me forget that I was listening to a mid-priced integrated amplifier, as opposed to my usual high-end pre/power setup. I found myself jotting down critical remarks in my listening notes because the Technics amplifier was that good. While it may not offer the absolute highest resolution, it compensates with a myriad of positive attributes such as power, impact, scale, drive, engagement, and excitement. Remarkably, it maintains a smooth and refined performance without sacrificing these dynamic qualities.
