Do I need a pre-amp?

I really appreciate everyone's valuable advice to help me get into the vinyl game. I am very excited for some rich, analog tuneage.

Would people recommend NAD for a phono stage? Recommendations on good lower-end units here would be much appreciated. My plan is to stick to a moving magnet cartridge.

Also, since it's often hard to tell the condition of a used turntable via the interwebs, would you say it's generally safer to stick to a modern edition, like a Rega vs the older Sonographe? I realize it's hard to make such a generalization but just curious on your thoughts.

Hey gang. Thanks for all the feedback. Little surprised to have to offer this justification here, haha, but in order of importance, here are my main motivations for the move to vinyl:

1) The sound - I favor analog's fullness to digital's cleanliness. I realize an analog amp is ideal, but due to financial considerations, it doesn't really make sense for me to make that jump today, probably. As zd542 wisely said, you have to start somewhere. 

2) The tactile experience of playing a record - It's different. You put the needle down and let it rip. There's no poking around and selecting favorite tracks. Listeners tend to hear a whole album as made by the artist 

3) The catalogue - Lots of old vinyl music isn't readily available in other formats

That said, I also love digital and have no intention of abandoning it. But with the opportunity for both digital and analog listening, this seems like a rare instance where one can have his cake and eat it too. No?

I think I'll follow the suggestions for a modern tt, considering I don't really know what I'm doing. I would love to be in the $300-400 range, but if I could snag a used tt below that, it would help free up some cash and could help motivate me to buy an analog amp. Speaking of which....

If I were to abandon my Marantz and pick up a solid analog amp, about how much would I need to spend, minimally? My setup is a pair of B&W 600 series floor-standing speakers + a separate B&W subwoofer. The speakers only contain a single woofer each so the separate sub is necessary, for my sound preferences. They are connected to the Marantz w some really fat bi-wire cables and the sound is excellent. At max vol, the Marantz isn't powerful enough to distort the B&Ws. I'm really happy with it but can only imagine if these speakers were connected to a solid analog source. 

So here's where I am today:

I can buy a tt + phono preamp for $5-600 +/-. Right? However when the time comes to buy an analog amp, I'll presumably eliminate the phono stage, which won't have much resale value, right? So maybe I should just splurge for the amp today. But what would I need to spend in order to match my setup? Also, is there a configuration that will allow me to keep the Marantz for my digital sources and switch to the analog amp for my tt? Also, what kind of analog amp will accommodate my subwoofer?

Thanks for helping the n00b!

Hey, I just wanted to re-express all my appreciation for everyone's feedback on here. Even yours @dbphd ;) 

As suggested, @mesch, I went with the Project debut carbon dc + orotofon red + Cambridge Audio Azure and it sounds totally phat! Even running it all through the Marantz digi there's a major audio upgrade with this config. So happy to have made the jump, now just beefing up my collection to keep the tunes jamming!
