Compressed sound from Marantz TT15S1

I’ve just renewed the pulley and installed an MC Project S2 phono amp on my Marantz TT15S1 turntable connected to my Marantz 8805 preamp.

Sounds horrid. Compressed and distorted. Speed is ok.

Settings I’ve used for the Audio Technica AT-OC9ML/II cartridge are:

Tracking force 1.5g

Gain 60dB

Impedance 100 Ohm 100pf

Any suggestions why this could be so corrupted?

The stylus is hardly used. Less than 100hrs.
