HDMI cable made a difference in picture quality??

Below is a copy of what I posted here on 8/20/2009 http://forum.audiogon.com/cgi-bin/fr.pl?fcabl&1250622275&openmine&zzNasaman&4&5#Nasaman

- Nordost Silver Screen: 8 (very bright, clean and details. Low noise). Highly recommend for High-end users.

- AQ hdmi-3:............ 8 (very deep, beautiful, and accurate colors. Great details & very low noise). Highly recommend for hi-end users.

- AQ hdmi-1:............ 7.5 (colorful, details, and low noise) Recommend for Hi-end users.

- Supra Cable v1.3:..... 7 (bright, clean, & details. Low noise & decent price). Good for Hi-end users.

- BlueJeanCable:........ 5 (decent colors, somewhat noisy & lack of sharpness. Great price.) Decent for Hi-end users.

- Monster-1000:......... 4.5 (its video quality is, somewhat, equally to BJC)I wouldn't buy it.

- MonoPrice:............ 2 (very dark, nasty, & inaccurate colors. Lots of video noise; it's a VCR's picture quality) Not recommend for Hi-end users.

The Wegrzyn's pure 4N solid silver HDMI cable is the best HDMI cable that I have ever tried. You can see fine details in the HD picture that were missing with other HDMI cables that I have compared them with!..

Once again, I have seen no noticable difference in HDMI cable output with the different cables I have tried.

It could be those seeing a difference are using some of those "Magic" power cables too, that "open up the soundstage, and reveal the inner detail".

Once again, spend your money on components that make an improvement in sound/picture, not on crazy cables.

And there you go.Cant go wrong hereabouts,cheers,Bob

I am really fasinated by the responses I have seen here. Some members claim to see sharper or brighter pictures. Can somebody explain to me how is it possible with digital? I mean, how can cables transmitting digital information apply filter to make picture less or more sharp, or darker or brighter?
