However, collectors argue that the analog "warmth" of the DEH-P01’s Burr-Brown chips beats the sometimes sterile sound of modern digital DSPs.
Most head units use off-the-shelf DAC chips. The DEH-P01 utilizes a high-performance 24-bit D/A converter specifically tuned by Pioneer Japan’s audio division. The result is a signal-to-noise ratio (S/N) exceeding 110dB. For context, a standard aftermarket radio sits around 90-95dB. This noise floor is virtually nonexistent, creating a "black background" where only the music exists, no hiss. pioneer carrozzeria deh-p01
