Has anyone here had any experience with the Nad 571 DVD player...How would it compare with a Sony NS900V?

It is based off the marantz 5200 player. It is considered very good in audio, including hdcd which I don't think the NAD has.

In that price range, I would consider the H&K DVD 50 and the Yamaha DCDI caurosel (though I am not sure on its price).

My DVD player is the denon 1600 and I think its very good.

Also it seems a bunch of companies, onkyo & integra, teac, and yamaha are coming out with new universal players for sub 1000.

Just a note to add, if you plan on utilizing some kind of an automated remote(not the one it comes with), while capturing the commands, use a wake up command first then capture the second press, NAD are notoriouse for the universal remote not seeing the first press....Just sayin'
