In my opinion, there's much value to be had in certain, vintage equipment, provided the technology is mature. I've got Threshold S-series amps (around fifteen years old) and love them to death. However, when I upgraded my CD player last year, the improvement wasn't hard to detect. I started with a Yamaha CDX-910 (eleven years old) and went to a Micromega Stage 2 (five years old).
