Adding an outboard DAC is a definite improvement. I started with the 63se as a stand-alone player, first added a Parasound 1100 DAC, then changed that out for a McCormack DAC-1. Each improved the sound a lot. I've just bought a McCormack SST-1 transport and sold the Marantz. The McCormack is another huge improvement, as it should be, but upgrading by adding the DAC's, shopping carefully for good used prices, meant I arrived at a set-up I really love without the pain of big chunks of cash flying away at any one time. A side benefit is being able to really hear the difference each piece makes isolated from any other change. I found that I understood more about my total system, even what the speakers were doing, than if I had upgraded in one jump.
Marantz 67SE CD player
Does anyone know if this CD player would benefit from an outboard DAC or a sound processor. It has digital outputs both coaxial and optical.I already have a Musical Fidelity X-10D connected between the player and my Jolida 302amp using the analog outputs and it sounds excellent now.Can I get anymore improvement in the sound.
