Sony Expands Line of High-Res Audio Components for Cars

Sony has expanded its Hi-Res Audio lineup for the road with a line of components slated for December delivery. The company announced Tuesday the RSX-GS9 digital media player/head unit ($1,499), XM-GS4 4-channel amplifier ($299), and XS-GS1 “super tweeter” ($199), which join a field of high-end loudspeakers for the car. The head unit is natively compatible with the DSD (5.6MHz/1bit, 2.8MHz/1bit) audio format. The Sony Digital Sound Enhancement Engine upscales lower quality files to Hi-Res Audio, the company said. Connections include Bluetooth, near field communications, two USBs and one micro USB, it said.
