Differences in sound quality AirPlay vs. Blue Tooth?

My stereo system in the living room died a few month ago.
Instead of going for a new one i'm thinking of buying a bluetooth adapter and a pair of active speakers.
Then i would use the iPad as my music central and play from there.
I did a wifi test with my AppleTv2 and couldn't found something wrong with the sound quality. Well my External Tv speakers are not high end but enough for me.
Will i get the same sound quality if i use bluetooth?
