Is there a way to improve the sound?

What file format do you rip to?
Kenny

Thanks for your question Kenny.  I must admit I do not know the answer to it.  I am an older audiophile, and I listen to records and formally CD's though the Bryston.  I thought digital was the future, and would lead closer to the "absolute sound."  The whole system was set up by the dealer.  If you do not mind, how woul I find out?  

PC: explorer > click on a ripped file > right click > properties
Mac: Finder > click on a ripped file > right click(2finger click on pad) > get info

You should avoid iTunes for ripping, use free XLD app on mac or someone else can suggest for windows. Always rip losslessly to AIFF or FLAC.
Use a tagging programs like MP3tag on windows or Yate on Mac to makes sure your discs have all the metatags(e.g. artist/album/title/artwork) you need.
Read the archives, this stuff has been explained SO MANY times. Youtube has video examples of people doing it all. Cheers,

Personally, I would not expect very good sound from CD-level formats (or below). I had my "digital" period but I much prefer vinyl. So perhaps you should reconsider the strategy. If Naim can do DSD or hi-res PCM you are closer to a good solution, I would think.
