There was an article a while back where the reviewer compared some music programs for the mac, ie..Decible(33$), and another one($$$) that i cant remember.  Anyway i am wondering what is the deal with the optical headphone output on the macbook pro with the dual core processor?  its my understanding that i need the mini toslink adapter to output a digital signal to my reciever.  does anyone here use this connection?  is there a better connection?  and can anyone remember which issue had the article?  thanks
