Rotel Bows 15 Series of Stereo Components With Hi-Res File Support Up to DSD Streams

Rotel bowed the 15 Series of audio components, touting the line’s integration of analog design with digital circuitry. The RA-1572 integrated amplifier ($1,699) has a high-capacity toroidal power supply and a 32-bit-768 kHz AKM digital-to-analog converter (DAC) capable of supporting direct stream digital (DSD) sources, it said. Features include photo input, front-panel USB input, Bluetooth aptX support, RCA and optical inputs and balanced XLR connectors, Rotel said. The RC-1572 preamplifier ($1,099) has two coax and two optical digital inputs supporting up to 24-bit/192 kHz audio, including DSD, and a rear PC-USB input for digital sources up to 32-bit-384 kHz resolution, it said. The $899 RCD-1572 CD player has a Wolfson WM8740 digital filter-stereo DAC that processes signals up to 24 bits at sampling rates from 8 kHz to 192 kHz, said the company.
