AudioQuest - Pearl 18 - 18Gbps 4K/8K HDMI Cable (Single)

AudioQuest's Pearl 18 HDMI features Solid Long-Grain Copper (LGC) Conductors. Specific attention has been paid to maximizing the performance of HDMI, and indeed Pearl 18 HDMI cables push sonic performance to new levels.

AudioQuest Pearl 18Gbps High Speed HDMI cables have the bandwidth required for video up to 8K/30, which is 7680 x 4320 resolution at up to 30 frames-per-second (FPS). 24FPS and 30FPS are the frame rates for almost all movies and many TV shows.

The Pearl 18Gbps High Speed HDMI cables support High Dynamic Range (HDR) and Dynamic HDR. HDR content expands the contrast of the image for blacker blacks and brighter whites/highlights as well as greater color saturation and brightness. Dynamic HDR  enables frame-by-frame HDR optimization rather than HDR settings that are fixed for the entire program.

Solid Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Solid conductors prevent strand interaction, a major source of distortion. The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.

Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
