There are no “high-end” changers.
As highlighted in the prior posts, they are discontinued legacy products found in the very low budget price point strata arenas found generally in thrift stores, on CRAIGSLIST and it’s equivalents, and popping up in neighbourhood garage sales.
Sure... CD changers may offer a certain esoteric CD party spin convenience factor to a minority of audio nostalgia fans.
But... and it’s a big “BUT”... they reside at the far bottom end of the budget to high-end audio component spectrum in both build AND audio performance.
