HI folks im in desperate need to pick some brains. In the quest to find cd sound to challenge my vinyl setup, i have made a couple of recent purchases. My cd player is a Marantz cd6000 oseLE which has a decent sound but no more than that. i recently purchased a used Denon dvd 2930 and have to say that it was a step up from the Marantz but still a long way from the turntable. I then decided on a DAC for the dvd and cd player thinking i would get a big jump in sound. I purchased a Musical Fidelity x-24k very cheap and in pristine condition. How does it sound? Well not really any different. On the dvd player voices may be slightly cleaner sounding but that is about it. Aso i thought it was to upscale cd but the red light on the front indicates 44 when the lights go upto 96. khz i think? What should i be expecting? My coax cable is an entry level Cambridge audio, do i need to invest in something like a Van Den Hul that costs a small fortune or will it be money down the tubes?
