A Rega Brio 3 would be a great option. It's a great little amp, and, while I haven't heard the phono stage myself, it's supposed to be excellent. Speakers are a personal choice, of course, but many people swear by all-Rega systems as excellent value for money, and the R1s are great and very unfussy about placement. Totem are also said to be a nice match with Rega electronics. A used pair of Dreamcatchers would fit your budget. If it were me, I'd keep my eyes open for a pair of Snell Ks or K/IIs or Audio Note AX-2s. I have an original Rega Brio and Snell K/IIs in my office (which together cost me $400 used), and it's a great setup.
