If I had 5K and an average sized space, I would do Vandy 2CESignatureII's (2300 or so) coupled with a Vincent SV237 hybrid class A intergrated from Audio Advisor for about 2300 including a great DAC
Just add an Oppo or Marantz player and yer set......
You could also go Magnepan 1.7i's instead of the Vandys.
