need help with choosing right cables

I agree with gregm and leafs...the entire source chain doesn't lend itself to much warmth. Cables might help a tiny bit, but none of the components you listed have warm characteristic to them, so its hard to imagine they'll do the trick. If I had to pick one thing to try, my vote would be to find a warmer DAC/CD and see if you can get the sound you want at the source. If the sound isn't right there, then there's not much that can be done down the line to make it a lot better.

Cheers,
Ken
