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?

Thanks guys. I would like to keep this under $500 and as small as possible, so no external phono preamp.
Taller order.

-Marantz PM5003 - built in phono - NEW
-Onkyo A955 - built in phono -USED
-Rega Brio - USED

older Japanese solid state integrated or recciever with built in phono section from the 70's. Probably need to have some parts replaced to operate to spec, but many of these had wonderful phono sections and tuners. Can struggle a bit with bright digital sources.
Don't go too cheap with Rega R1's. The better the amp, the better they will sound. On the flip side, don't overspend on a bedroom system. That's why I went with the Outlaw RR2150. If that is out of the question, go with the something like the NAD C315BEE or 320BEE and the NAD phono stage.
