I am not an audiophile expert so I am wondering what people's opinions are on this subject.

It seems like having a digital out on your digital audio player would be better than an analog line out. The player would have to convert the digital signal to analog and it seems that being able to to do that conversion would be better on a high quality reciever.

Do you think that a digital audio player such as the Karma should have one, or does that not really make a difference?
