I own the Philips 963SA which I modded with the blackgate cap in the power supply. It's hard to beat for the price (about $430.00 with the mod). I am not familiar with the NAD units, though. Past DVD players include Denon DVD5000, Denon DVD2800, Denon DVD2800M2 and Denon DVD9000. All my denons died, some multiple times, and the DVD9000 ($3500.00) died in under a week. Anyway, back to the Philips; great bass, smooth mids and highs with no glare, and excellent soundstaging. Great on SACD's too, though I only own about a dozen. And, if it dies in a year or two I will not be upset.
