Well, back a few years ago, The $ensible $sound ran an article comparing an $80 RCA 5 disc player, DBT against players costing $1000s. No one could differentiate between them. After further use, the author declared that RCA as bullet proof as well
But, as was mentioned, if you use the digital out, you have even less of a reason to worry, unless that $80 player doesn't have a feature you really need.
