Monoprice HDMI Silver vs. Copper

Any recommendations from the Audiogon community on the benefits of silver plated copper vs.just copper Monprice brand HDMI cables.


I see Pangea has silver plated copper and silver plated Ohno copper HDMI cables. I really like the Ohno copper in my Audience cables.Another to consider.
Audioholics did a nice test of HDMI cables and my take away was that cable length was the dominate factor. I suspect that a short cable cares not who makes it. Look the test up and they list results versus vendor.
Newbie question here- At what point to runs become "long"? I need about 10 feet. I'm guessing 25 feet or longer would require the thicker guage, but if I'm wrong, please correct me.
