Buying an old Wadia or Meridiean CD player

Hello,

I've got about $1,500 to spend on a new CD player. At the moment I'm using an Ah!Njoe Tjoeb 4000 fully optioned. I've been considering a used Wadia 830 or Meridian 508.24. Both are a decade old and I'm wondering whether this makes sense. Am I likely to hear an improvement over my current player? Should I go for a current CD player and, if so, which one.

All advice appreciated.

Mike
