RP600M upgrade. Anybody using a Willsenton R800i with the Buchardt s400mkII?

Hello everyone. I am considering an upgrade from my RP600ms. Budget is around 2000 dollars. Im really interested in the Buchardts but I am wondering if they pair well with my Willsenton R800I? If anyone with direct experience could shed some light on the combo that would be really helpful!

I love the dynamics and soundstage of the Klipsch's and that is something that is important to me. I also love the Willsenton so I don't want to replace that : )

I listen to everything really but especially Jazz, classic rock and techno.

My DAC is a Denafrips Pontus II .

I'm also open to other suggestions for speaker around the same price range. The Buchardts have caught my eye from thier descriptions from reviewrs and also thier size and looks as well as the free shipping and taxes.

Cheers!
