Less volume with a more powerful amp

I used to own a Onkyo receiver and have since bought a Marantz AV 7005 Pre-amp plus a Rotel RMB 1095. I used to listen to music at -15db but now have to turn it up to - 6 or 7 db to get the same volume . The new setup has 60 watts per channel more power.

Amp gain (sensitivity), not output power, determines the necessary level setting.

Is particular amp sensitivity a predetermined engineering goal for a given design or is it an incidental outcome?

I do not think there is a single answer. Since it is interdependent with other design parameters, it is not an independent variable.

Obviously, sensitivity needs to fall within a useful range for commercial success but some designers have specific targets and others do not.

I don't mean to pester you but is high sensitivity commensurate with a low noise floor given all other performance parameters are of a high standard?
