Hi Eben,
Coming from a c-j fan I would say the PV-10AL that you currently own is just a entry level h-fi piece. Music starts to happen when you get into the c-j 17LS2 pre (or higher up in the c-j line like ACT2). Keep your amp but think about getting a new cd player like the Linn Ikemi paired up to a pair of Spendor or Harbeth speakers in the future.
Good Luck!*>)
