Perhaps the Mogami garden hose coloured the sound much more than the DHC cable. It was warmer to my ears than stock as well, but the lower end seemed more prominent. Bass was tight though and did not bleed into the midrange.
It may also be testament to how good the stock cable is if I cannot perceive a significant difference between it and the "neutral" and supposedly "better" DHC Molecule. I'm not discounting the possibility that differences may be more apparent through more revealing components, but I do find it unfortunate that people seem to think a cable upgrade is a must for the HD650.
