I'd say it's up in the high end of the spectrum of equipment out there. as long as you're rips, and encoding is good.. you can really hear how bad 128kbit sounds, even when driving.

my setup:

Xtant 403a amp
JL audio 12" sub (12W6, 3 ohm wired)
VW monsoon mains. (1" tweets, 6" mids)
monster cable RCA's

12gig red mk2 -- 080000125
