The HDMI standard allows a single multi-conductor cable to transmit digital audio and digital video. Previous video standards (composite, "S", component, RGB) transmit an analog signal. When two digital devices are connected by HDMI, the digital signal does not suffer being converted to analog and then back to digital. While HDMI and DVI-D connections offer the possibility of superior performance, all cables are not all equal. The picture and the sound can be compromised by lesser cables.
HDMI is backwards-compatible with DVI-D. For example, a DVI-D source can be connected to an HDMI input either by: 1) DVI-D cable + DVI-D to HDMI adapter 2) DVI-D to HDMI Adapter + HDMI cable. The more inclusive HDMI standard will eventually replace the DVI-D standard. We believe HDMI cables are a better investment. Please be aware that digital audio from an HDMI source will not be received by a DVI-D input.
Audioquest/CinemaQuest HDMI-X uses large 1.25% silver conductors. Foamed and solid High-Density Polyethylene are used to minimize loss caused by insulation, and to insure critical geometry stability. Two RF Stoppers prevent interference problems.
