gerryah930,
I live in the Monroe area and have visited Paragon Audio often, nice people, nice store.
Now, this is only my opinion, but the Watt Puppy 7's can be pretty harsh sounding in the upper mid/high area. That is probably why you like the tube sound to soften the puppys.
I use a Bryston BDP-2 usb player. I spent awhile ripping my CD's onto a 4 TB Hard drive. (and then recopied to another HD for back up).
Now, I can access any song in any order easily and the sonic quality has not been reduced.
