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 ?

Petty: Where do you get your acid and how do I get some? It's painfully obvious that all of your posts on this subject scream the same thing: You are scared to learn about computer audio so the easy thing to do is bash it.
@Tmsorosk, you mention in your original post that you are using a power conditioner. Disconnect the computer from the power conditioner. Just plug the 'puter directly into the wall. See if that changes anything for you. Is your power plug polarized or unpolarized? If unpolarized, flip the plug (reverse the polarity) and see if that does anything.

I see we haven't had responses from you in quite awhile... wonder how things are going with this project?

I do not ascribe evil motives to anyone. I just don't think computers are a viable alternative to a top notch transport.digicable/DAC setup. Just look at the threads of people having constant problems with hardware/software/etc. And I use computers every day; use iTunes regularly; use dbpoweramp, etc., so it is not computerphobia.
