Why is my turntable sounding so muddy?

TT mounted on good solid surface, tracking weight correct? Tubes okay?Correct tubes in sockets? Cartridge worn? 

TT is mounted on a Target stand tracking is correct I thought about the tubes but the CD player is working fine maybe the phono tube? I tried two cartridges one did sound a little better then the other. I am an analog 
person and never could I ever say that the digital sounded better in my system. Thanks for the reply I am thinking about a new table anyway.

Cartridge can age. The rubber mounting for the cantilever can harden and affect compliance. Get a new cartridge and all will be as it was!

hollytone22,

I had a Linn Axis years ago and really liked it. I wouldn't give up on the table unless you think it has a mechanical issue with speed or the bearing. If it's working correctly, no reason to replace it. I would look at a possible problem with the cartridge. Maybe the cantilever suspension has hardened and lost its compliance.
