Sony - XO-D4 / CDP-M20 Stereo set - Multiple models

The Sony CDP-M20 compact disc player and the accompanying Sony XO-D4 all-in-one audio system form a classic vintage midi-set from the mid-1980s. The XO-D4 central system combines an integrated stereo amplifier, an AM/FM tuner and a 5-band graphic equalizer in one recognizable chassis, ideal for a compact stereo-conscious setup.
The standalone Sony CDP-M20 CD player forms the digital extension of the set and is known for its fast and reliable transport with a clear, dynamic 16-bit D/A conversion.
Important note about operation:
The integrated cassette deck of the XO-D4 no longer functions (likely worn belts, a known phenomenon with devices from this period). The other components of the set – the amplifier, tuner, equalizer and the standalone CDP-M20 CD player – function properly.
Condition:
Nice vintage condition with normal signs of use consistent with age. Technically tested: amplifier, tuner reception, equalizer and the CDP-M20 CD player work as they should. The cassette deck of the XO-D4 system does not work.
