IF you're dead-set on something from Best Buy, well, then I'm outta steam but, if you want something a little better, then
this NAD unit would make a nifty centerpiece for a quality system, and it's small to boot.
The price still leaves some wiggle room for sone decent bookshelf speakers. Scout out some from the same place if it interests you. If you're interested in this concept, speaker suggestions can be provided.
It won't be as gaudy as the all-in-one stuff you can get but it will be clean, simple, very, very good sounding, and should be of more than decent quality.
