you might get more responses from people searching the forum threads if you ask about the proper model designation for the Ayre: KX-R. All of their preamps begin with the prefix letter K.
As for your answer? I owned the previous top of the line Ayre, K1 and auditioned the full MBL reference line when I bought my MBL 101E speakers. I have hear the 6010D numerous times. It has a warmth that is inviting but in the end I found the detail too suffuse. I have not owned a Pass preamp since the Aleph P and imagine the sound has changed a lot in the intervening 12 years.
Note, the XK-R is a great Jaguar sports/GT car.
