The Lumin D3 is right around $3k new and sounds great. I use it in a second system, it sounds like a junior version of my Lumin U1x (soon to upgrade to U2x). The Aurender A1000 is pretty nice as well. It sells for around $3500 but you should be able to find a dealer who will give a discount.
If you are willing to buy second hand the options open up more. Various Lumin, Aurender, Auralic, Naim, Hifirose, and others.
