PS Audio’s I2S digital audio interface is a critical link between source and DAC. The better the HDMI cable, the better the sound coming out of your loudspeakers. Carbon 48 HDMI adds 5% silver-plating to its solid-core conductors for high-speed data transfer. Like all AudioQuest HDMI cables, Carbon 48 uses Solid High-Density Polyethylene Insulation, and precise geometry. Specific attention has been paid to maximizing the performance of HDMI, and these HDMI cables push sonic performance to new levels at this price point.
