I happen to like Transparent Reference XL cable as well. I do find that they tend to slightly roll off the highs a bit and are not as fast as a few other cables. The gentle rolling off of the highs happens to compliment some systems quite well and is definitely not a negative if you have the right system.
While I like them a great deal, I did find something that I like even more... Nordost Valhalla. I find them to be the most transparent and holographic interconnect I have listened to. When Transparent releases the Opus IC, I have no doubt that it will be as good if not better in the areas you are concerned with. This will come with a huge price tag. Right now though, the Valhalla is the best I can recommend.
