Dave, I think you will waste money if you get a cheap dac. I beleive that to beat your player, you have to spend doube of what the player costs, as far as a new source component. I don't know your speaker cables, never heard them, but if you want faster sound and more detail, plus more controlled bass, you may want to try Audience AU24 speaker cables or Acoustic Zen HologramII speaker cables. I think your interconnects are fine. I have the same ones. They do have nice bass, but also are pretty detailed. I'd suggest looking at speaker cables. Also, power cords could bring a nice improvement. If you didn't upgrade PC on your player, I'd recommend Audience powerChord. Works good with digital. What integrated are you using? Is it tubed or SS? Does it accept balanced interconnect? Id yes, you may want to try Sony balanced.
