What is the max length that an HDMI cable should be for the best quality?

For an HDMI cable for use with a PS3 and an HDTV, what is the maximum length that it should be?

I remember some sort of rule of thumb whereby if the cable is longer than X feet, it will not be top quality.

Thanks for any info.

Depends what and who you listen to

Most will say between 8 and 12 feet while others will say up to 24

I think 25feet is cutting it, And you might need a thicker gauge wire. Though, at 50 feet, even the best cables migh fail and I hear you can buy some equalizer to boost the cable to work at those lengths. I once check and it did not seem to be expensive at monoprice.com.

Try searching AVSForum.com, they probably have answers there.
