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?

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.

The A47 has a very low 20k input impedance, suggest you stay away from tube preamps, one because they can be an impedance mismatch, two they are also capacitor coupled, and if that capacitor is not big enough it could roll the bass off too early.
My suggestion is to go with a direct coupled solid state preamp, maybe the Ayre’s K1XE, I would ask Charlie Hansen (Ayre) if it’s direct coupled.
