Hi,
I'm in the same situation as the OP,
I have a mac mini, amarra, apple tv and a lg home cinema (I know it's not really relevant for audiophiles but you know the kids and sponge bob....). So basically, amarra plays flac files through airfoil to the apple tv connected via toslink to the lg. I use apple tv as the mac is located in another room.
So, I am hungry for some advice for a reasonable budget
Regards,
Raz
