Specs from the CJ site:
The DF1 combined a superb line stage preamplifier with and integral CD transport.
An infrared wireless remote control was included. The DF1 could be used as a stand-alone CD player or as a unit combining the preamp and CD functions in a single chassis.
The DF1 was known for conrad-johnson’s superior imaging, depth, and soundstaging.
CD Player:
The DF1 CD mechanism uses a single laser beam that does not require alignment. The 176.4Khz sampling rate and noise shaping circuitry yield 16 bit resolution, and allow gentle filtering well above the audio frequency band. Digital to Analog converters are employed to eliminate phase shift between channels and avoid switching glitches.
Preamp Stage:
Unlike most CD players that use IC’s in the line stage, the DF1 uses discrete FET analog circuits with separate discrete regulated power supplies—circuits which have proven reliability and superior soundstaging and imaging.
The DF1 uses the highest quality component parts. Precision tin-oxide resistors, polypropylene capacitors and polystyrene capacitors and premium quality controls are used throughout the DF1.
