I have a Logitech UE Smart Radio that is used for background music. Nice sound, it's sonic sins are of the omission variety, it fills the large space but in Logitech fashion is no longer available however the Grace Digital Mondo (Doublej's #4 suggestion above) is very comparable. My gripe with it is the need to reboot it (and software on my computer if I want access to my ripped files) every so often.
