My frst choice would be a nice pair of full range speakers , Maybe something nice looking like vienna Acoustics etc.
If that is not possible There are many inwalls that are excellent. For example Speakercraft makes expensive in walls that you can get which also have two enclosure options, foam and metal. The enclosures make a huge difference.
Lastly my advise for the best system is to get the best source. A better CD player or Dac if your doing a music server will make a bigger difference that the electronics once they are past a certain point.
