Pro-Ject Debut Carbon DC with Ortofon 2M Red Cartridge: BASS sounds 'muddy' The Reason?

Hey,

I just picked up a Pro-Ject Debut Carbon DC Turntable and have mixed feelings about the sound quality. The Bass is prominent and not ’tight’ (unlike my cd player) Some tracks sound good and others not so much.

My system consists of a pair of B&W 630’s, an old Denon 50 watt reciever (DRA-550) from the mid 80’s, a Marantz CD5004 cd player.

Also I’m probably going to be in the market for a new preamp/amp with a built in DAC soon. Would that solve the problem? Or do I need to upgrade the cartridge? If so please leave a link!

TIA
