I just watched lord of the rings extended version and I found that the dts es sound had less bass than the dd one, which is often the case with dts. Can I increase the bass on dts without altering the DD bass, or do I constantly have to change the settings when altering from DD movies and DTS?? And also.. I get the best sound from my dvd by connecting it via coaxial, that should sound better than connecting the five? analogue outputs from the DVD players decoder to the amp??
