A beautiful NAD L53 DVD/Receiver with a temperamental DVD drive, sometimes it works other times it doesn't. I would suggest that instead of an expensive repair (over $300 from NAD Authorized repair center for a new drive unit), the simple addition of a good quality progressive scan DVD/CD player (which I bet you already own) plugged into the units AUX input is the most economical solution.
Cosmetically, it's a 10. The Amp & Tuner sections are flawless.
