You can't go wrong with either of them. They are both fine players for the money. But I would lean more to the Rega myself.
Music Hall cd-25 or Rega planet 2000
I'm looking to upgrade my current cd player, a sony cdp-315. After doing some research here I'm considering a used rega planet 2000 or a new music hall. Currently i'm listening exclusively on hd600's with a ASL mg otl mkIII by going direct from the player to the amp. music ranges from jazz->classic rock->independent artist
