Which pre should I choose?


I have an Accuphase A47 to drive my Dynaudio Coutour 1.3SE. I want to choose a pre-amp to match my power amp. and the speaker system. I prefer classical music. My room is not big. But I like warm and sound with thickness. Do you have good suggestion? How about Ayre's K1XE or Audio Research R2 MKII?

But the new Accuphase such as C2420 are quite expensive. It costs about US$8000 here in Taipei.  This gear has few review in everywhere.
Regarding SA-2000,l I have heard once, but not as good as SA-5000.  It is rare chance to find SA-5000.
How about the Accuphase C-290. It is almost 20 years old. It is selling at US$4000 here in Taipei.
