About the DP-78

The Accuphase DP-78 is a premium SA-CD/CD player renowned for its separate transport and digital processor sections, enabling independent use and upgrades via option boards like HS-Link. It employs a single lens/twin pickup high-speed access mechanism, dedicated DSP for digital servo, and an advanced MDS++ D/A converter using six Analog Devices AD1955 delta-sigma converters in parallel per channel for superior performance (improvement factor of √6 ≈ 2.4). The player supports high-resolution formats including 2.8224 MHz/1-bit DSD and 192 kHz/24-bit PCM, with digital inputs/outputs for external sources. Additional features include text data display (disc title/artist), strong precision-machined chassis with high-carbon cast iron insulator feet, and the RC-100 remote control. It excels in SACD playback with exceptional sound quality, though some users note it performs best with SACD over standard CDs.
