good day sir, but then again most mp3 i see are encoded in 128 bits only, would this still beat fm radio?
My opinion, MP3 player still the better choice (I might say advantage). First, FM is a radio transmission, there are a lot of factors for distortion (e.g. weak signals, location etch). FM signals depends on how good is your receiver for a real stereo sound poor multiplexers.
MP3 player if you have a large storage you can store your favorite song and can play it again & again in a discrete signal unlike fm signal you have to wait for the DJ (wait....i'm out of topic).
Listen to a good MP3 player lets say iPOD you will be surprise with the sound no matter how much the encoded bits.
(BTW, I'm talking about portable system. Using sophistacated tuners & system is another story.)
