Technology

By combining dedicated research with creative thinking,
the Accuphase engineering department has developed numerous proprietary technologies.
Some of these are explained here.

MDSD (Multiple Double Speed DSD)

MDSD is a new technology for further reducing noise during playback of Super Audio CD (SA-CD) sources.

AAVA (Accuphase Analog Vari-gain Amplifier)

Revolutionary preamplifier topology that eliminates conventional volume controls from the signal path.

DS-DC (Direct Synthesis-double Cancellation)

Software-based demodulation used for FM reception.

MCS (Multiple Circuit Summing-up)

Drastic improvement of S/N ratio through parallel connection of amplification circuits.

MDS (Multiple Delta Sigma)

Innovative D/A converter technology resulting in significantly improved THD and S/N performance.
