A CD player or transport at $5,000 to $10,000 treats disc playback as a serious format, not a legacy holdover. Transport mechanisms are damped and isolated to the standards of high-end turntable engineering. DAC sections run fully balanced architectures with premium conversion chips or proprietary R-2R ladders. Power supplies are oversized and independently regulated. For collections built over decades, a player at this level makes familiar recordings reveal layers you've never noticed before. You'll hear things in albums you thought you knew inside out.
