I recently purchased an Arcam AV9, but now I consider this purchase a waste. The salesman indicated he thought the unit could be upgraded to receive audio over HDMI for the new high def audio codecs, but I have since found out this would require a hardware upgrade. I would not buy the expensive pre/pro in light of this fact as it is obsolete on arrival. Once you hear the new audio codecs, you will understand what I mean. They are another league in movie sonics. This is simply a warning just in case one was considering the AV9.
