Please recommend components for newbie with $1K

I currently have a late-90's Sony cd player, a pair of old Realistic speakers that are hand-me-downs from my father-in-law, and a Scott 418-A integrated from the mid-70's (I think) that I acquired at a pawn shop when I was an undergrad. Sounds pretty bad, so I want to upgrade. I can put in $1000 now, so I want to get speakers and an integrated amp or a receiver. I guess that gives me around $500 for each. I need the amp to have A/B speaker switching. A phono stage would be nice too, although I'm not opposed to getting a separate phono preamp in the future if necessary. This system will be a smallish room, about 14x10, 8' ceilings.

Unless I can find something used, I'm leaning toward the Marantz PM7200 integrated. Local shops have also suggested the Integra DTM 5.3 receiver. I would buy the NAD 720BEE today but it's $540 before tax.

Thanks for reading. Any amp and speaker recommendations will be greatly appreciated.
