Full Range under $5k-ish

At new and based on your less than 5k budget I would strongly consider and recommend  you listen to Vandersteen. There is a reason the model 2 have been so popular for 40 + years. Maybe they won't fit what you are looking for but ANY recommendation of a reasonably  priced "full range" speaker should include the Vandies. If you require more bass you can add subs later. 5k on a full ranger, to 20k no less, won't get you there. More important is what sounds right to your ears, room and works with your music preferences and current electronics. There is no simple right answer. As with all speakers, better electronics will yield better and more satisying results. Vandies are most forgiving but capable of true high fidelity sound that produce music at a very high level the more attention paid to realize their potential.
