STELLAR AudioQuest Carbon 48 HDMI

Product Description

The AudioQuest Carbon 48 HDMI cable is an excellent, curated match for PS Audio Stellar products, offering a high speed, effortless, sonic experience when connecting I2S digital audio through our HDMI style connectors.

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.

This product qualifies for our risk free in-home trial in the continental United States when purchased directly from PS Audio. Break-in on AQ Cables may be required for optimal performance.

5% Silver-Plated Copper Conductors (HDMI)

In AudioQuest HDMI cables, increasingly thick layers of silver plating are applied to AudioQuest’s Long-Grain Copper (LGC) conductors to improve Noise-Dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit on overall performance—a superbly cost-effective way to maximize a digital cable. Carbon 48 uses 5% Silver-Plated Copper for its conductors.


AudioQuest “48” HDMI cables can transfer up to professional 10K Ultra-HD video. The 48Gbps bandwidth is made possible by 4 balanced audio/video pairs capable of 12Gbps each. The precision and tighter manufacturing tolerances required to produce HDMI cables that transfer up to 48Gbps bandwidth mean many of AudioQuest’s tried-and-true ingredients and techniques are more important than ever before.

Level 3 Noise Dissipation: Carbon + Metal + Directionality

Traditional “100% shielding” is not enough to guard against the increasingly prevalent effects of Wi-Fi, cellular, and satellite radiation. In AudioQuest HDMI cables, all 19 conductors are Direction-Controlled to minimize the RF Noise that damages performance by “directing” or draining it away from the most vulnerable circuits. Level 3 Noise Dissipation adds a high-loss carbon layer to further enhance noise-dissipation. Additional Noise-Dissipation techniques (Levels 4 and up) are applied as budget permits to further reduce noise.
