Having secured delivery of my new Michell turntable I'm now considering looking for a second hand CD player to bring my CD playing quality up to a similar level. I'm slightly worried about buying a player that uses a discontinued laser block/transport assembly given that Sony and Philips have both discontinued quite a lot of commonly used parts. I'm looking at brands like MF and Linn. Should I be cautious/worried or can these machines still be repaired with alternative parts should they fail? Do CD players last longer than I'm thinking?
