I am using the Transparent Ultra XL (balanced) between my VT100 MKII and LS25 with spectacular results. I do not find these cables "dark". Instead, I would characterize them as being neutral, dead quiet and dynamic, with exellent extension in the mid and low bass. The treble is natural and certainly, not "rolled-off" in my system (I have ribbon tweeters, MG 3.5/R)
