The reason i ask the question below about the mp3's, is that a client recently hade an audio system installed, nothing at all over the top (Yamaha receiver) along with a rather cool Sonos mp3 player. As far as i can tell, it is basicly a hard drive which is connected to the receiver and it gets it files loaded on to it from a the home pc. The Sonos has a very cool remote that has an iPod like GUI.

To make a long story short, i had a stack of disks on the job site and Lisa loaded them onto the Sonos via iTunes on her pc an i was astounded at how different the sound quality was when listed against the original cd it was burned from. Dynamic range was down and the soundstage and imaging were very flat compared to the wav. file. ...and i don't even have a very good set of ears!

Was the difference in the mp3's or the Sonos? ...or is there an installation problem with this particular unit? Eager to hear any thoughts you might have on mp3's.

I know, i know; i am supposed to be listening to the music and not the sound, but i feel as if i am only getting 90% of the music.
