Input:
I searched for a nice system for my Mom and I found this cd player, speakers and amp in realitively short time, ordered them, boom bam boom and here they come in like the next day; I was really suprised.

Very nice setup; the amp I ordered some speaker wire and that was shipped with it, but thats another story, look for the AV review and see that.

Folks at Amazon do a cracker jack job in my humble opinion, and I appreciate having the world at my fingertips.

Thank you Amazon :))
