We have all experienced that desire for something completely new.

Suppose you were to get rid of everything you currently own and build a new 2-channel music system from a clean slate (for a 10 X 20 ft room, with CD as the only source.)
1) What would you consider the minimum expenditure for this to be worth doing at all?
2) What would be your top choices of what to get? (Including electronics, and also pro vs. consumer, bookshelf vs. tower, etc.)
(I am actually considering this, but only after saving for at least several months. No point getting what I can afford now only to be disappointed later.)
