downloading music versus cd `s quality


Greetings
I have been reading a lot about quality of digital music, and the question is: can I transfer all my cd~ to my Mac, then upgrade the sound quality on the Mac , via a software program, or do I need to start from scratch and download music that is already in HD?
also, can someone explain the difference between regular cd and 24 Bit/192kHz ? What is the best way to get digital quality music, in other words? Much obliged.
I am a digital neophyte!

Looks like the HAPZ1ES has a lot of fans I'm sure. I'm still looking to explore the world of digital sans CD player and really like the all-in-one aspect of the Sony but am not willing to give up my rather pricey separate Dac so... Here's the $64 question: IF enough consumers say "Pretty please" will/would/might Sony consider putting a digital output [especially for and including for hi-rez] 'out the back' of it?
I'm sure they had their reasons for NOT doing it initially or they would have? ...but would they really be losing more biz IF they added it at this point? I for one, would definitely make the purchase! Are you listening Sony? Thanks in advance?!?!
