I just auditioned some HD800s with some stock cables and some Cardas Clear cables in my home this week (library loaners). I did feel like I heard an improvement with my rig (Grace Design m903 using the 1/4" HF jack) in terms of bass response, airiness of the sound stage and smoothing out the high frequency. These are $536 cables. I mostly listen to jazz, blues, rock and classical music.
I am convinced that cables can enhance their performance over stock cables. I just don't know which ones to consider. So I could just buy the Cardas Clear cables OR I could consider some other aftermarket options from ALO Audio, Cardas, Double Helix, Moon Audio, Norse Audio, Stefan Audio Art, or Toxic Cables for example. Given my DAC/Amp, musical tastes and the HD800s what aftermarket cables should I consider along with the Cardas Clear?
