I'm thinking of upgrading my DVD-player. My system is currently made up of consumer-grade equipment, with a JVC D723 prog-scan DVD player, and a Yamaha HTR-5240 receiver. About 5 years ago, I had the opportunity to audition a NAD CD player at home, and I was stunned by how much better it sounded than my old JVC CD player. This experience has got me thinking about NAD DVD players as an upgrade. Does anyone use a NAD prog-scan player? How is it? And, is there something comparable in price/quality that also has DVD-Audio capability? One more question: would my DVD player be the best place to start my upgrade? Or should I start with the amp instead? I watch my DVDs on a Mits WS-55807 HD RPTV, and I have Polk RT-series speakers and a Velodyne CT-120 sub.
