19907 📃
PIONEER amplifiers and tuners catalog, September 1990, built around the Clean & Real concept - minimal signal path, no unnecessary circuitry. The flagship A-838 takes up a full spread, followed by A-636 and A-535 (¥39,800) with Source Direct and Non-Switching Circuit Type II. Notable are the DAC-equipped models: A-90D and A-50DV with built-in D/A converters and digital inputs - Pioneer was clearly orienting around CD as the primary source. Tuners F-757 with DDD filter and F-535 with Silent Tuner and CCTS. The AV line SP-91D (¥125,000) and SP-700D (¥83,800) with speaker selectors. All prices exclude consumption tax.
