@orrman, I have a very similar set up to yours. I own the Enleum 23R and my system consists of a Aurender W20SE, Holo May KTE, Rega P10, and Luxman EQ-500 phono stage. My speakers are the Klipsch Cornwall IVs at $6600 MSRP. Yes, I know that is above your budget but I bought CW IVs brand new for 25% off the list price including delivery to my home. When I bought it (March 2021), the list price was $6000. You might even be able to find a used pair for less. BTW, I'm also into headphones and I have the Susvara, 1266TC, Utopia and ZMF VO.
The 23R and the CW IV are a fantastic match. Dare I say even better than the 23R and the Susvara. I have a REL S5 subwoofer in the system that completes the deal. I've tried 2 tube amps with the CW IV in the same price range as the 23R. I preferred the 23R with the CW IV. You could also look into the Klipsch Forte IV but I would get the CW if you have the space and the budget.
