I came here searching for the exact same issue with my Parasound P6. The volume is "low" until I crank it up to the 70's or thereabouts! I am glad I am not the only one with this question/confusion...
I may be selling the P6 since its a little too neutral for my taste. Almost lifeless compared to my cheap old NAD-1155 pre. :(
