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.

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?

The significance of the gain and of the SNR is dependent on what you feed it. I do not know what you mean by "the threshold of signal loss."

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.

Actually, a lower sensitivity (higher numerical value) is commensurate with a lower noise floor.
