set up question cambridge

I recently purchased a cambridge 840e and 840w. My speakers are sonus faber grand piano home. My question is I need to set the volume control at the -30 level about 2'o clock leval to have any real volume to my speakers (scale -96 to zero). On my previous amp peachtree decco 50w the volume set at 9 o'clock was the same as the cambridge unit 200w. I checked the connections a couple of times and it appears to be correct. It just appears the cambridge unit has a somewhat muted sound or something is not right with the unit. Any reccomendations to trouble shoot this will be appreciated.
