I guess the alternative to getting a tuner/2 channel amp/CD player would be to get another micro type "all in one" system. The audio quality with their current Denon was pefectly ok for them. Or the other option would be to get a 5.1 channel amp (with tuner) and add a CD player. Space is another issue as their is limited room where this will have to fit. I'll have to do some solid measurements before going to far.
