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.

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

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?

Okay, thank you. I guess what I'm getting at is where the threshold of signal loss begins. Is it interdependent on the gain of the pre or will it occur at a certain point regardless? And will the noise floor begin to add to it? Or is it a separate issue?

I'm assuming there's a point at which the lack of sensitivity begins to prevent part of the signal from being transferred or amplified.

Thank you all for putting things in perspective.
