jerryyeatman:I don't think home cinema / hi-fi enthusiasts mind spending say £20 on a HDMI cable rather than £10, for a bit of reassurance that their more expensive cable has a slightly higher built quality. I object to "high-end" manufacturers claiming that their cables costing four or five times as much (same spec/length) actually perform any better than the £20 ones, when the £20 cables (or even £10 ones!) can be repeadedly demonstrated to pass bit for bit perfect data (assuming same lengths and same specification).
I'd go along with that, and I'd like to thank posters for some of the recent links. I know for some people it is just going over old ground, but I feel I know a lot more about hdmi now than I did a week ago. All the technical articles suggest to me that cable reliability may vary, but that a poor cable would manifest its faults in unsubtle ways. Before my aerial upgrade, when the Freeview signal dropped in quality, the manifestations were pixellation, picture freezing, and sound dropouts. This is what I would expect from any fault in digital transmission. I accept that by paying mega-bucks for an hdmi lead you may reduce the chances of this happening, but I can't undrerstand how two digital cables performing to specification could produce results that vary from each other. Yet we read reviews claiming improved picture clarity, sound and motion handling. I just don't understand how this could work. I remain ready to be further educated, but at the moment I remain skeptical.
