Running a Yamaha R-S700 receiver with Axiom M3s.

The Natural Sound is awesome.

The receiver has a phono input, where I've plugged my turntable.

When I play records, I need to take the volume way up to -8 or -12 to fill the room the way I like.

But when listening to the Sirius tuner or the nice CD-S300 through this receiver that great volume level is reached at about -25 to -28. Those would be unbearably loud at -8.

Is this normal?

I also have a little NAD photo preamp in a drawer somewhere Model PP2.

Would that be better than the receiver's built-in phono port?
