Preamp for Parasound A21?

Just got a pair of Thiel CS2.4 and want to pair them with Parasound A21. However, I don't really like any of Parasound's preamps. The JC2 is very nice but overpriced (to my pocket anyway). The other Parasound pre's don't really interest me. I don't really hold out much hope for the forthcoming P5 either.

Anyway, can you suggest a pre around the $2000 mark that will mate well with the A21 and the Thiels? Also wondering if a tube pre might be a good idea in this context? Would much appreciate your thoughts and suggestions. Thanks in advance.
