    The Pioneer A50DA Amplifier is an amplifier that is open to all current end music formats. High grade phono inputs deal with signals from record players; four golden cinch inputs are ready and compatible with almost all different types of players. A highly modern ESS ES90165 D/A converter that has been based on the ESS SABRE Ultra has been included to deal with all digital formats. An asynchronous USB transfer allows the Pioneer A50DA Amplifier to support ultra-high-resolution material with 32 bit and with a sampling rate of up to 384 kHz, and DSD with nearly four times the rate (11.2 mHz).

    The Pioneer A50DA Amplifier's switch output stages have been specially developed by Pioneer to enable its use with a music supply of 90 watts per channel. A large mains transformer that features separate windings for the power amplifier is included. A pre-amplifier and controls ensure the consistency of a stable feed, including highly dynamic encoded material.

    The Pioneer A50DA Amplifier is constructed from sturdy material to ensure it is robust, including the thick aluminium front panel with five metal knobs, the massive screw terminals and a high grade remote control that allows for ease of control and provides hours of enjoyment.
