Naim/Linn/Arcam to match Proac response 1sc?

A novice needs experts' advice on chossing an amp to drive Proac response 1sc.

I have been looking at (all used)

- Linn Classik music
- Linn Majik i
- Naim Nait 5i
- Arcam AVR300
- Arcam A85

but can't really decide. It doesn't really have to be multi-channel since I will only hook up my DVD player to external input. What would you go with?

I prefer crisp, clear midrange and fast-responses. That is also why I chose Proac response 1sc.

Thanks in advance.
