Yes, but Monster uses oxygen free copper. * *That was their claim to fame

At least in the case of speaker wire there was some remote basis to
argue that the characteristics of the cable could affect the sound
quality because the signal is analog. *Not saying that I believe their
oxygen free story, just that the cable characteristics do have an
affect on the analog signal. * In the case of HDMI, all you need to
determine at the ends of the cable are if the signal is high or low,
ie 1 or 0, so there is far less basis to believe a typical HDMI cable
needs to be anything special.

Hmm,
Really? digital bits should have no phase jitters to maintain signal
quality.

Not true. The digital signal can have phase shift as long as it's not
large compared to the bit interval.

They can have any phase shift you want, even larger than the bit interval
(satellite TV has a almost an astronomical phase shift ;-). Phase *jitter* is
another animal. Cables don't introduce phase jitter, though.
