I wouldn't change components until I looked at proper setup first
are you using stock power cords? If so they rob a system of dynamics, bass and sound stage.
are you using vibration/isolation products again the right devices add a lot to the dynamic mix.
are you using good power conditioning?
are you using effective room treatments?
if they answers to the above are mostly no then you should take your $5k and look at getting the performance out of what you have first and then and only then would I look at hardware changes.
