Right match

I was using luxman 505ux11 it sounds much better than the m8 preamp I had cornwall iv and forte iv connect with the preamp I have to turn tte volume up to 75 db or higher to get high sound at 65 db you can barely here the music at 75 db is louder but sounds very distortion not what I expected not what preamp should I buy

Thks

Something is wrong. Do what tablejockey suggests.

Seems like a luxman preamp will be a better match.

What is your source? Are you using an output of a turntable connected to a line level in on the musical fidelity preamp?
Luxman has a built in phono stage…that’s the only explanation I can find other than your preamp is broken. 

I'm using the preamp not using the luxman anylonger
