Masongsong- here's my 2 cents worth.
I have no idea about your Dad's Denon, but moving to the PWD, fed uncompressed files would likely yield a noticeable improvement in resolution. Further, once you've controlled a digital front end with an iTouch or the like it's hard to deny it's contribution to listening enjoyment due to easy access to your library. I'm an old (53) purist myself, but I moved from an Exemplar CD unit to a Mac Mini, using a great Dac, and I found greater resolution, greater convenience, and more musical enjoyment.
Having said all that, it's hard to argue that it's ones job to "enlighten" a man who is already happy with the music his system delivers.
Whatever your Dad decides to do, you sound like a great son and I'm sure he enjoys the debate with you- so keep it up.
Have fun!
