DAC for Rega Planet 2000

I have a Rega Planet 2000 and wonder what DAC would go best with it. I would like to pay about $500 or less used. I am looking for more dynamic range and better detail. I would like to tighten up the bass as well.

This all started when a friend loaned me his Meridian 508/24 which has incredible bass and detail, can I approach this sort of performance with the Rega?

thank you
