Don't give up on the Planet. It is solid and can be upgraded simply. New powercord, some Ensemble cones and good stuff will happen. Love the deck and the Proac 2.5s. Can't love the Krell but it is quick.
I would go to an outboard dac. The perpetual tech. P3A with the rega i think would probably sound better than either of the two cd players. How much are you looking to spend on used equipment as the fmj costs a lot more than the planet.
