The preamp section of the Arcam is a passive unit? I didn't realize that. THAT could explain the whole thing.
A 33K Ohm input impedance for a power amp might be a bit too low being fed by a passive pre, especially if the output voltage on your source is less than 2V. Your amp would probably need to be in the 47K-100K Ohm range.
Good luck!
