Does anyone out there NOT hear a difference in CD

CD players all sound different just like other components, but most CD players these days are at least decent...I've never heard anything decent in good working order that sounded BAD on a decent system.

Generally, I think 20 or 24 bit oversampling is a good feature to look for in terms of getting a player that doesn't cut corners.

Music is an art.

Recording is an art based on science

Audio is mostly a science.

A successful system is one that works well as a whole and consistently allows the key elements of the recorded art to shine through and produce enjoyment, despite the inherent technical flaws accumulated via both recording and playback during any particular listening session.
