Sorry in advance if this is the wrong forum for this ... I have a music collection on my NAS that I like to play on my home surround speakers (via an AV amp). I TEND to use the music player on my laptop to send via Ethernet cable as my laptop software is the most flexible. I am considering changing my Blu ray player to an "all singing" one that also plays/streams music. My question is, Is there any difference in quality between an MP3 sent from a laptop to the amp than from an expensive Blu ray player? Thanks!
