The purist would say the best for the money is the one you put together instead of buying a box set. Along this line of thinking the receiver is the heart of any system, it needs to be a pristine, a powerful heart to pump power through the system. The most important spend would be the receiver or amp. An amp will provide noticeably better performance over any AV receiver because an amp does one thing. It powers the speaker from the source material lighting up one's ears.
