rayhall, i respect your comments and spent 6 months considering alternatives after i first heard the opus before i finally purchased it. in the context of my system they made a larger performance increase than any change i have made. i would simply recommend that until a person hears what a product can do they refrain from assumeing that "it can't be worth the money". would you think $40k for speakers would be unthinkable. if these cables make more difference than additional money for speakers wouldn't they be equally as valuable? or is it more politically correct to buy more expensive speakers?
an analogy i would use to describe the special quality of the opus speaker cable would be that comparing it to the next best cable i have heard (nordost valhalla) it is like going from a darkened room to full natural sunshine. no other component has ever done that at any price.
i remember when i first heard about a $300 set of speaker cables; i thought that the idea of $300 for cables was laughable. over time i have come to appreciate what enjoyment my system can bring me and how cables affect performance. there is no right and wrong on this issue; only context, perspective, and taste.
