i agree with gmorris that if anything most transparent cables (except the opus) are somewhat dark and closed in compared to the best of the rest. that is why they mate so well with the somewhat bright krell gear (i'm sure not all krell gear is bright). also, some earlier wilson designs (not the watt/puppy 6s) are certainly on the bright side and again the transparents match well with them. the stengths of the transparent cables have always been dynamics, bass slam, true timbre, and great detail and resolution. the best of other cables seem to be missing some of these qualities but are more open and extended in the highs; many times these other cables don't control the high frequencies properly and the sound becomes fatigueing. i agree that transparent is rarely a great buy but at used prices it can be a very good buy. since transparent is such a popular cable on the used market many times people's opinions on transparent are formed with designs that are old or out of date so consider that. i have one set of xlo limited in my system and i slightly prefer the transparent ref. xl but i like the xlo also.
