New Rega R1 - Recommend an Amp?

I just purchased a set of Rega R1s from a seller here. Now I need an amp. This is for a bedroom stereo. I will pair this with a Rega P2 and a TBD CD player. Definitely need a phono preamp and headphone jack. No tuner or video needed.

I'm considering new or used. Does anybody on the forum own these speakers and have a recommendation?
