Technics Network Audio Amplifier SU-G30

While on silent display, the Technics Network Audio Amplifier SU-G30 ($3,999) web page is chock full of good information. For example:
JENO Engine (Jitter Elimination and Noise-shaping Optimization)
Jitter is a major cause of distortion in digital systems, and is caused by mis-timing in the master clocks used in digital-to-analogue 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, optimising the noise-shaping speed, the degree and requantisation error, 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 the new generation of Technics digital amplifier designs to reproduce the natural and delicate nuances of music.
And this:
High-speed Silent Hybrid Power Supply
With a conventional switch mode power supply, the switching frequency changes in response to the load fluctuation in order to control the switching ON time for stabilising the output voltage. This fluctuation component in the switching frequency has a negative impact on sound quality. The newly developed power supply reduces the noise component harmful to sound quality by fixing the switching frequency. In addition, the latter stage in the switching power supply is provided with a linear regulator to stabilise the output voltage. The linear regulator uses custom, high-definition electrolytic capacitors. What's more, the resonance power supply decreases the level of switching noise, and the PFC (Power Factor Correction) reduces primary current peaks and higher harmonics. The parts used for absorbing noise, such as capacitors, were carefully selected. All possible measures were taken to achieve low noise and reproduce clear sound.
Nicely put, no?

The DLNA-enabled SU-G30 outputs 50wpc (into 8 Ω/doubling into 4Ω) and offers 1x Line in, Phono (MM), 2x Coax S/PDIF, Toslink, USB-A, and USB-B inputs, Bluetooth (aptX Low Latency, AAC, SBC), AirPlay, WiFi (IEEE 802.11a/b/g/n), and Ethernet (100 Base-TX / 10 Base-T) inputs. It supports most file formats up to 32-bit/384kHz and DSD256 and Internet Radio (vTuner) and Spotify (what, no Tidal?).

Digital Noise Isolation Architecture
The SU-G30 Network Audio Amplifier receives audio signals from various digital content devices, such as NAS, PCs, USB memory devices, and other digital inputs. Many of these digital content storage systems were originally designed for use with PCs, so low noise – which is required for pure audio reproduction – was never a main design concern. To handle these often noisy sources, the SU-G30 isolates the interfaces for these media to exclude external electrical interference, and also employs a jitter remover, thus offering clear and stable sound, free from noise and distortion.
