What Shardorne and 4est said. Also, talking to Apple guys about two channel is a complete waste of time. I've used firewire and toslink out of my Mini going to oversampling and NOS dacs while achieving amazing results with both.
Mac sound quality
I'm using the new IMac , burning my CDs in AIFF . Its hooked up to an audio grade power conditioner , power cord and run to a Levinson #360S dac from the digital out through a audio grade digital cable . The sound quality is not nearly as good as my mid fi CD player . Iv'e read many posts saying this type of hard drive is far better than good quality CD players , too many posts to disregard . What am I doing wrong , the other posters were down loading , but can there be that much difference ?
