Why is computer based music mostly "close but..."?

[wgscott]

Purchased music on hard drive ----> Computer (2012 Mac Mini, Audirvana 2.x) ----> [ USB | coax | optical | ethernet cable ] ----> DAC works perfectly.

 

Every time I trial a streaming service, I get bored with it.  There are only so many times you can listen to "Pearl Jam tunes for babies".  I decided it was best to own what I want to listen to more than once, rather than pay to rent.

 

I got rid of vinyl 25 years ago.  My CDs have been in boxes in the garage for at least the last 8 years. No need to go backward.
