no doubt since the release of iPod, music industry has changed throughout the world. days of CD's no longer the only source.
sometimes u got to admit, a thumb drive can store so much of songs. so convenient and its free sometimes where u can even download hi-res file.

but the fact remains(to me):
CD's does sound better compared to lossless audio.
cons of lossless audio:
* they do sound thin, bass not as full and many more.

why?
dunno..didnt bother researching why, as i am happy with the current source. it doesnt require a 'golden ear' or trained ear to hear the diff. if a system is 'revealing' enuf, u can hear the obvious difference!!

some will swear by it dat it doesnt makes a difference, but other will say otherwise.

no need to debate, as this topic has been discussed all over the world for many many years oredy.
juz google them..

note: whichever u believe is the best source or no difference, there's no right or wrong. as long ur happy dats wat matters!!
