I've got a P75 Mk ii that I'm using with my DV20X2L. Before that I had a PS Audio GCPH. The P75 I find is a very good match for the DV20X2L. To me the sound is not bright or harsh. I've read reviews that say it can sound "thin," but fortunately I have not noticed this yet. But I try to apply smoothness through the use of all PCOCC interconnects, and my amp is a Yamaha A-S2000, which naturally sounds a bit smooth.
