The D/AC-2000 features a state-of-the-art 20 bit D20400A dual digital to analog converter and custom AES 21 digital interface receiver designed and manufactured by UltraAnalog, Inc. The D/AC-2000 also incorporates the High Definition Compatible Digital®PMD-100 HDCD®process decoder developed by Pacific Microsonics. This decoder performs precise decoding of HDCD encoded recordings and also functions as a superb digital filter that will enhance the sonic quality of non-HDCD encoded recordings
