Technics SU-C700: Integrated amplifier with an unusual design

First of all, it is worth noting the unusual design of the Technics SU-C700. At 34cm wide, it falls somewhere between full-width and half-width amps; The rigid aluminum body comes in a silver finish only.

Large VU meters take up a fair portion of the front panel; when the amplifier is turned on, they are illuminated, the brightness of the illumination can be changed. The construction and finish of the Technics SU-C700 is impeccable and the attention to detail is admirable.

For this Technics model, a Class D amplifier circuit was chosen – not the most common for this price segment, but suitable for a compact case. As a result, the device does not get too hot during operation, but requires a more careful selection of speakers. To optimize sound, a Load Adaptive Phase Calibration (LAPC) function was developed. When enabled, the SU-C700 sends a test signal to the speakers to determine their electrical characteristics and adjusts output accordingly.

We recommend dedicating part of your setup time to this procedure: you will hear the difference with your own ears – when you turn on LAPC, the sound becomes denser. A significant difference between the Technics SU-C700 and competitors in the price category is the built-in DAC and a large number of digital inputs. In the list of analogues there is only one linear and one for the MM phono stage; There are many more digital ones – three coaxial, optical and USB type B port.

Unfortunately, that’s where the good news ends. Technics’ sound is seriously lacking in energy; due to weak rhythmic drive, the music turns out to be illegible and disorganized. The catchy compositions lack enthusiasm, and the more tender ones sound too dull and dull.

Features of Technics SU-C700

Fully digital amplifier with high precision signal jitter circuit and PWM converter
This amplifier is completely digital. Its specially designed circuitry reduces signal fluctuation and accurately converts PWM
distortion, noise, and audio “shaking”.
LAPC (Load Adaptive Phase Calibration)
Adaptive speaker impedance equalizes amplitude and phase response. Result.
represents the reproduction of sound with a rich spatial impression.
High Speed ​​Linear Power Supply with Lower Noise
The combination of a high current Schottky diode, a rectifier circuit with a large capacitor and a regulator
power circuit generates an amazingly high quality power supply with low noise and high power.
