Right match

Also I was told that the input impedance has to be 11 times lower on the preamp than the power amp the power amp has 50 Kohms the preamp 75KO can that be the issue also im not using the luxman I have turn the volume to 80 db to be able to hear the music at 64 db is like 7 on the clock something is wrong 

The question is: do you have a phonostage between TT and preamp line stage? Many preamps have an input that says phono however it is meant for an external phonostage. 

A followup to that is: does the phonostage provide for low output MC cartridge if indeed you are using one. A MM phonostage will not provide the gain needed for a LOMC cartridge.

The M8 has a phono stage, according to the website, claiming for both MM and MC.  So along mesch's lines, (1) did you plug the TT into the phono input and (2) if so, did you plug it into the MM or MC input?  From your description it sounds like you might be using a lower output MC but going through the MM input.

Right the TT is plug into the phono input MM but it sounds horrible a $5000 preamp should sound great with any distortion and at 60 db I can't barely heard the music

What cartridge is on your turntable?
