I don't treat them as a source at all. Last time I went there they

that elsewhere.

If they are HDMI then they are £1 in poundland.

Yes but the HDMI lead I bought from Poundland led to strange things
happening because the internal wires had no screening or twisting. I
eventually went crestfallen to pay Maplin's ransome. I minimised this by
being adamant with the salesman I didn't need gold plating.

Actually (decent) gold plating is quite a good idea for signal integrity
medium/long term. But *only* if the mating socket is gold plated.
Which most of them aren't.

Most gold plating is a very thin layer, where the metal below has a
habit of migrating through the gold and then leading to an oxide layer.
Better than nothing though.
