Here's a conundrum I'm having with my home theater set-up. I figure there must be a few tech-heads out there that can lend some informed suggestions. My set-up: NAD 750 Dolby.DTS receiver B&W Stereo, Center, and subwoofer Cheapo back speakers DVD player; optical audio connection Here's the problem: dialogue is very quiet. When I'm watching TV, I have to crank the volume all the way up. This can't be right. The same happens when I watch DVDs. When I listen to music on the DVD player, though, the sound is nice and loud, the way it should be. The problem can't be the DVD player, since dialogue is also quite when watching TV. I thought it might be the center speaker, since dialogue is primarily sent to the center speaker, but it doesn't sound any better when I set it to use only the stereo speakers. Any suggestions?
