I have a customer who has Zu Druids and an Art Audio Carissa. He is super happy with the combo. Full disclosure, I have no affiliation with Zu but am the importer and re-seller for Art Audio.

With preamp, this would be over your budget. However, I have a stereo Carissa coming in on trade which I am going to be selling for $4500. He is upgrading to our Harmony Silver Integra. I am just about to relaunch our VPS preamp which is a dual-mono preamp that will be available for $4000. The VPS is such new news I haven't even created the product for sale yet.
It would come in a bit below your $20K budget at $18,500.
There are a million other options. I happen to know this would be a very good combo. You could probably use the extra $1500 to get a sub to go with the Druids.
