I am not referring to the cost, but to the quality, that usually has a cost, though since big corporations acquired the famous brands, like Harmann Kardon with Mark Levinson, the quality falls down. The point with cd players and, more with TT, is that they have more then PCB inside them. The most usurable parts are the moving ones.
Like cd mechanics. Some serious brands improve existing mechanics in order to achieve better sound and durability. Other simply buy insertions in High End magazines.
It's been my experience that while the quality of sound that a CD player produces may be proportional to its cost, the same cannot be said for its ability to read some (damaged?) discs, particularly when it comes to CDRs. I think some of the "high end" things they do to the more audiophile players - I dunno, more focused lasers or something - often come at the expense of tracking ability. My default player to check otherwise unplayable discs on is a cheap CD boombox - it plays what others can't.
