Well maybe what you are hearing is that vinyl is a challenged medium. Noise, distortion and dynamic range are all far less than what real music needs, or than what digital sources can deliver. Hence a muddled sound.
Marantz cd players are excellent, so if the sound is still harsh, it is either your expectation that is wrong (real music can sound rather harsh), or the speakers, or the hard acoustics of the listening room.
In any system the weakest links are not modern electronics, but the speakers and the room. If it is the speakers, try auditioning Harbeths. They excell at avoiding listening fatigue.
