I used to own an Arcam A22.
I found it a nice looking and solid amp but depending on what music you listen too, at what volumes levels and with what speakers its too be paired with, it may not suit.
I used it with PMC IB1's for a few months and found it lacking in bass and power/loudness ability. Its built in protection circiut kept cutting in. The IB1 is a 4ohm speaker.
My source is an Arcam cd33.
I then added a Krell FPB200 power amp and fliped an internal switch in the A22 to dissable its power amp and stop its protection circuit kicking in.
