Best speakers I have heard for $4k are by a French company called Atohm. All of their drivers are designed in house. Great soundstage, great imaging and since you have a sub you will be extremely pleased. They have a unique setting on the back where you can adjust the sound to 3 different variations depending on your room and amplification. Recently demoed Totem, Harbeth, Spendor, Trenner and Friiedl and found the Atohm to deliver the best sound. By the way you can also get stands for them very inexpensively if your needed that as well. They also make a matching center channel.
if interested can connect you with a phenomenal dealer. PM me.
Good luck and let us know what you decide on!
