Will high price HDMI cable makes a difference?

I have to go with it makes a difference. There's plenty of people on AVS (the majority even) that will go on and on about how transports are all the same, cables sound the same, CD players sound the same, etc. In my experience, that's not even close to the truth.

The HDMI cable that came with my Panasonic DVD player went dead in less than a year. Other than that, the picture was excellent. As for the connection from my TV player (Sony HD) to the Direct TV box, I returned my $120 Monster HDMI cable after I compared it to a much cheaper Blue Jeans cable and saw absolutely no difference. That being said, since my HDMI cable for the DVD player went on the fritz, I've been playing DVDs through the component cable hookups. No difference except I like that less wires are involved with the HDMI cable.

Of course a "better" cable will probably make a difference - I have seen it as have countless others. The argument about cost boils down to a matter of degree and what you are willing to settle for. There is obviously no "right" answer here, just what is "right" for you. There definitely is a difference between a $5.00 cable and a $150. cable from a reputable mfg. - the question is what are you willing to pay for that difference? To argue there "is no difference" is either naive or foolish and only points out that some people are incapable maybe of "perceiving" a difference, not that there is none. Everyone's ears and eyes are different and we all look and listen for different things.

There are no "experts" in this - you are the expert for your gear. That's part of the beauty of a site like Agon where you can try different cables, etc.

Just my $.02

Will the differnece be that great between 19 vs. 100?

Unlike analog signals or clock timing signals, there should not be the slightest difference between digital signals if the cables are within tolerance and the bits are getting through. The whole point of digital is to elimiate the dependence on analog signal accuracy by sending a stream of two widely different states with clearly identifiable positions that remain clear given any vagaries in transmission/power/noise etc...i.e. a clearly disernable stream of what may be accurately identified as ONE's or ZERO's.

Of course a very poorly manufactured cable may give problems - but this should be the exception and not the rule.

Are you kidding me? To argue there is no difference is naive or foolish? Isn't the opposite true? To argue there is a difference when there's no real proof or evidence is naive and foolish. The argument that some people are incapable of perceiving a difference also seems ridiculous. Listen, I have a very high-end Sony HD TV, and I saw no difference between the cheap Panasonic HDMI cable that came with the DVD player and expensive Monster cable. I think that it's naive and foolish to think that there aren't a lot of companies out there who try to take advantage of our DESIRE to see or hear differences when there is none.
