PAUL'S REFERENCE AudioQuest FireBird 48 HDMI

PS Audio's newest choice for our Reference System

Only AudioQuest HDMI 48 cables can transmit the full 48Gbps of data required to fully optimize today’s HDMI 2.1 equipment. AudioQuest FireBird 48 HDMI cables are guaranteed to have the 48Gbps to enable the highest possible HDMI data streams in technological history.

FireBird 48 features 100% Perfect-Surface Silver conductors that have been direction-controlled for the most efficient dissipation of radio-frequency noise; high-loss graphene is added to the carbon layer and a “global” high-loss carbon layer is placed around all conductors.


Preorders accepted, shipments will be fulfilled in March, 2021.

PAUL’S REFERENCE AudioQuest FireBird 48 HDMI

Product Description

The new AudioQuest FireBird 48 HDMI incorporates AudioQuest’s highest-performance, lowest-distortion Perfect-Surface Silver conductors and is Paul’s newest pick for the I2S interface between products in Music Room II.

The AudioQuest FireBird 48 HDMI cable is Paul’s newest and greatest pick for PS Audio’s Reference System, known around the world as one of the highest resolving audio systems. FireBird 48 is the perfect solution for audio applications from our I2S interface.

AudioQuest’s new 48Gbps HDMI cables offer greater bandwidth and higher performance than their predecessors. Perfect-Surface Technology is applied to extreme-purity silver conductors for unprecedented clarity and dynamic contrast. Also featured is AQ’s Noise-Dissipation System (NDS), incorporating six alternating layers of metal and carbon-loaded synthetics to “shield the shield,” combating distortion caused by RF Noise which contaminates digital and analog circuitry. FireBird 48 and PS Audio, the hand-curated best.

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.

Solid 100% Perfect Surface Silver

Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.


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.

Carbon-Based Noise-Dissipation System

While it’s easy to accomplish 100% shield coverage, it’s far more difficult to prevent captured Radio Frequency Interference (RFI) from modulating the equipment’s ground reference. That requires AQ’s Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical “reference” ground plane, which in turn causes a distortion of the signal. NDS’s alternating layers of metal and carbon-loaded synthetics “shield the shield,” absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.

Level 6 Noise Dissipation: 72V DBS + Graphene + Global Carbon + 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. In Level 5 Noise-Dissipation, high-loss graphene is added to the carbon layer and a “global” high-loss carbon layer is placed around all conductors. Level 6 Noise Dissipation, AudioQuest’s most advanced and comprehensive means of addressing induced radio-frequency noise, incorporates all of the sophisticated techniques found in other models and adds AudioQuest’s patented 72v Dielectric-Bias System.
