Hi guys, I'm hoping someone can help me with this. I recently was watching and listening to Rush's R30 concert dvd on my small 2 channel setup. My receiver is a Panny XR10. The dvd has a DD 5.1 track and a PCM Stereo track. The PCM track sounded great on my setup and the 5.1 was really, really low and almost muffled by comparison. The 5.1 track sounded like it was at about half of the volume of the PCM track. I know a 5.1 track downmixed to 2 channel will not sound ideal but the difference was unbelievable. The movies I watch with DD and DTS tracks usually sound fine on my setup. Out of curiosity I pulled out my old cheap Sony DE595 receiver and the results were the exact same until I applied the Digital Cinema Sound movie sound fields while listening to the DD 5.1 track. This made the 5.1 track louder than the PCM Stereo track and all of the individual instruments were more defined. The Music sound fields (Hall, Jazz, Concert, etc) did nothing to improve the 5.1 track at all but the Cinema Studio EX A,B, and C all made a world of difference to the 5.1 track. Do these type of DSP's often make this big of a difference?
