behind the HDMI is the convenience of one size fits all but as far as quality goes, I doubt it makes any difference. Just my guess.
First question, is there a noticeable difference in audio/video quality between using a component cable connection, (they are monster cables) and HDMI cables? The next question, if I bought HDMI cable to connect my DVD player to the TV is there actually a difference say between the $50 cable and the $120 cable. Unbiased opinions would be appreciated, personal experiences?
