The best CD player for rock music that I found is the Linn Genki or the more expensive Ikemi, combined with all Linn electronics and Linn speakers. You can find the Linn cdp readily available in the used market. Alternatively, also try the Adcom 750 or the Arcam FMJ (also used); both of which have great dynamics and output excellent bass. In regard to the Rega, I have had no experiences with any of their components, so I can't comment on them.
Good luck and happy listening!
