Rega is a great great choice IMO.
You could get a used Brio-R in your price range. They are truly excellent. No headphone jack tho. If you're patient you could get the newer model Used for $650-$700. It will be well worth it - something that can remain in your system for a long time.
I've used my Brio-R to drive many different speakers - since it's small its easy to bring over to someone's house if you're demoing used speakers - it has never disappointed or failed to drive anything. I've had Marantz, Rotel, NAD, Yamaha amps all in that price range and the Rega always sounded best. It's super fun and always projects the rhythm and emotion of the music in a way the others don't.
I've loved my Brio-R for 3+ years and recently upgraded to the Elicit-R after trying several other $1.5k-$4k amps - again the Rega was the clear choice. And still using the Brio-R for my kitchen speakers.
Also you'll be surprised how heavy it is, especially for it's size!
