That's a difficult question to answr because it depends on how much SACD listening you (plan to) do. I have an SCD-1 which I definitely want to keep even though I don't listen to a ton of SACD, and want to improve the redbook of the SCD-1. That's mostly because I think the SCD-1 makes an amazing transport. I've some experience with the DVP 9000 and know that it has some issues with the flimsy tray, so as a transport it may not be the best option. There are mods out there for it, but as you can get one for 650 used, I think putting more money in doesn't make a ton of sense. If you're concerned with redbook play mostly, then get a dedicated cd player, but as you have a dvd player now for your sacd and cd playback, than I think you're probably better off gettin a universal (sim, ayre, linn?) player. So what do you plan to use it for mostly, because without knowing it's hard to say wether an outboard DAC is better or not.
