I just purchased the Kenwood 6070, then I realized I didnt see any specs on a RF modulator for Laserdisc DD5.1. While I could use my old amp as a preamp, that would be very wasteful of space just to get the RF mod for my Starwars LD. All of my other 5.1 LDs are out on dvd now, so its just starwars that I am concerned about. Yeah I know Im gonna get spanked for not watching the original thx only version. So anyway, what mode should I use to watch an LD like starwars. Does Pro logic 2 or matrix thx sound as good as DD5.1. Will I notice the difference. I am excited to be able to add some new sound to some older movies that are 2.0. Can anyone fill me in on how the translation from 2.0 to 6.1 sounds.
