the taiwanese bootlegs claim hdcd, but of course they're probably just normalized tracks pulled off of retail american cd's. really, hdcd and the like is overrated when it comes to average music. dvd quality audio doesn't stand out from cd when you have music like hip hop, which is primarily synthesized with 44.1khz instrumentation.
that being said, saying a cd sounds like a tape because of a balls system is a little far fetched to me.
