Howdy. I bought this NAD pair a month or so ago, but I've had a nagging problem. Playing music with the CD player the unit performs extremely well, and watching TV in surround mode also sounds great. When using my DVD player though, it seems as though I'm not getting near the juice. I literally have to turn up the volume almost 20db to get any real sound. My DVD player is at least 5 years old. Does anyone think a new DVD player will make a difference? Thanks in advance for any help.
