analog newbie questions...

Since I brought up the 640p: I like Ortofons but have others that I prefer more, Goldring 1012gx or 1042gx and a Shure M97 for lower priced cartridges.
Interconnects: Under 1M can cause set-up issues sometimes.
I was always told to try to spend an even amount on each piece of gear, TT, Amp, Speakers, phono pre should be less.
Buy a used integrated with the assumption that you will upgrade eventually. Stick with newer stuff to avoid problems.
Speaker Cable: Don't buy garbage, at least 12 gauge. Get decent banana connectors. Even Madisound & Partsconnexion have some very inexpensive bananas. Avoid the twist on types.
Finally, some dealers get amazing prices on close-outs and B-stock. They are an option. AudioAdvisor was suggested and can be great. I like Spearit-sound and Echohifi also.

This is all great stuff! Thanks everyone! One question, with the marantz pm-5003 int amp, would I still need to purchase a phono pre amp, even though the int amp has a phono stage included?

Nope. Phono pre-amp = phono stage.

No, you will not need a separate phono pre-amp. Any integrated amp which has a built-in phono stage will allow you to plug your turntable's wires directly into the amp. Move the amp's selector switch to "phono," turn on your turntable, drop your stylus into the LP's lead-in groove, and enjoy the tunes ! It couldn't be any easier.

If you are seeking speakers, take a look at the Kirksaeter Prisma 210's. I liked them so much I bought two sets and am using one set for rears in a HT. Very efficient great speakers. I think Rick at Audioforce still has a great deal on them. I am not associated with Audioforce, just a satisfied customer. If the deal is still running the pair will come with a free center you can sell if you dont want it for even a better deal.
