In the future I would like to expand it to CD and Radio units.
I wouldn't hold-off on that. CD (or other digital sources) are better than analog and a cheap CD player usually sounds just as good as a high-end one. If you have a TV associated with all this, then just get a DVD/Blu-ray, which will also handle CD's. You can also, of course, just rip any CD's and play them through a connection to your computer or portable player.
