I'll start this thread in a way that normally makes me cringe, however, doing so mayhelp me get the problem sorted, so here we go... MY SET UP CONSISTS OF (AAARRGHH!!!) a Pioneer DV 05 Elite DVD player, a Denon 3801 receiver and a set of Boston 555 THX certified speakers. (I'm actually saving for a big Denon at the moment). I have a problem on DTS soundtracks. It started with the Rock criterion edition and I thought it must be a one off disc. The DTS track sounded muted and lacks any sort of oomph. However, Air Force One and The Fifth Element Superbit discs are the same. On the Fifth Element, the DTS track is clearly 4 or 5 db lower than the Dolby Dig version and lacks the edge that most people say DTS has over Dolby. Other DTS discs I have tried are Jaws, Galaxy Quest and MIB. These sounded fine to me but are DTS only discs so there is no Dolby Dig track to compare them with. Gladiator sounds fine in ES mode so I am thinking that it must be the quality of the disc, though I thought that Superbit discs were full bit rate DTS tracks. Anybody else have a problem with these or any other discs?
