MARK LEVINSON No30.5L
¥ 2,800,000 (released in 1994)
Commentary
The D/A converter with the latest digital technology applied to the No30L to further improve the sound quality.
It uses a 4-layer board with separate lines for the music signal, plus / minus power supply, and ground. It reduces the power supply impedance and also suppresses the generation of time axis distortion by improving the transient characteristics.
Custom-made Voltage Controlled Crystal Oscillators (VCXOs) reduce jitters to less than 20 ps.
Full 20-bit D/A conversion is achieved using a 24-bit digital filter and a custom-made 20-bit dual D/A converter.
Equipped with two digital inputs via RCA terminal.
You can enter the source name from the front panel.
Upgrade from No30L is possible.
