could any of you technologically-informed subscribers briefly explain the differences between (and rate from best to worst) the following theater sound systems? HPS4000 Kintek Digital Dolby SR does the quality ever vary depending on what the film was recorded in? also, should one always opt for a THX theater if one's available? are the sound setups in THX theaters generally as good as, better, worse than any/all of these others? thanks for any info. monica dorenkamp rutgers [log in to unmask] ---- To signoff SCREEN-L, e-mail [log in to unmask] and put SIGNOFF SCREEN-L in the message.
