Cables can make or break you, but you need to remember that NAD stuff tends to sound overly warm and smooth in exchange for details. I am a strong advocate of proper power delivery/noise control measures and will strongly suggest you start there. The more revealling a system the more harsh noise (glare) will sound. If you start at the source you'll be able to tell if this is the right direction and then work your way down the signal path. Since digital equipment consumes so little power you can do this rather inexpensively. Get a little 2-3 ampere ONEAC isolation transformer from eBay ($15-25), clean all the contacts inside & outside w/ DeOxy and treat them w/ ProGold. Use that on your CDP and listen. If HF glare goes down then keep working on the upstream side of your player until you can improve no more. Then move down the signal path. I would get a Porter Port cryo'ed outlet and a decent DIY based design power cord for the CDP(Bob Crump, Chris VenHaus). I have a CEC built belt drive transport and it reacts very favorably to power cord upgrades. The same goes for my little sister's NAD receiver. I had a surplus military grade, silver plated copper, Teflon power cord hardwired to it and the improvement was stunning. Bass improved tremendously and the vocals became smooth and airy.
Here's the testimonial of someone who followed my suggestions:
Power conditioning and cryo treating
I have tried DH Labs Silver Sonic interconnects and they just didn't make the cut in my system. Perhaps some solid core copper like the Straightwire Rhapsody II's or Tice PC3 will be what you want. Don't forget to allow your system at least 100 hrs for break-in.
With psychic power and primal intensity,
