It's like the old axiom...you listen to "hi fidelity", and stereo is how you listen to it...or, with the newer technology--Dolby 5.1, 7.1, DTS, etc.
Record my Ipod with 1.444, heck with the 128 crap. Of course instead of an unlimited number of recordings, can only get about 12 CD's per 8 gigs. That's like 9 to 10 hrs of music for a trans-Pacific flight of 13 hrs! And with noise canceling headphones, viola--listening nirvana (almost)!
Incidentally, did a test quite awhile ago with an OSHA inspector about perceived noise. Used a quality personal cassette player and a real cheapie (prices were $229 vs about $29). Both were tuned to the same FM station, played in stereo and used the same headphones. Turns out that the cheapie volume was turned up to around 86 to 88 dB and with the expensive one...the avg volume was around 70 dB or less to get the same perceived noise level. According to OSHA, hearing damage can occur at a volume level of 84 dB for one hour, and it's permanent. The moral of the story is that compressed or crappy sound, when turned to a high volume to achieve a perceived listening level, is a self curing problem...the victim will eventually suffer hearing damage and none of them will buy compressed music, becuz they can't hear it anymore.
Of course, this isn't a very nice way of looking at it, but politically correct I'm not! I'd like to help those that insist on ruining their ears, but they probably won't listen...or can't.
