Do you have tin ears?

The problem I have found with cables is that they are system dependant. There seems to a synergy that must fire on all cylinders to maximize the performance. Some cables can take a day or two to settle in when just being moved. So doing A-B comparisons becomes difficult if not impossible. We have to have an equivilant to a photographic memory, (Audiophonic memory?)when trying cables back and forth. Sometimes you get lucky and the improvement a glaringly apparant. Other times I have found that the difference are so minute, that we may convince ourselves which is truly better out of desire to stop searching and settle. Years ago I tried a number of cables and a couple from each company and finally decided on the brand/model based upon the A-B comparisons. It is a hassle and takes a lot of time and money. If you have tried a number of cables and not coming up with a noticable improvement then I would say one of two directions remain to go here. Either be happy with what you have or continue to search for the grail. There most likely is a cable that will make you stand up and say "wow my system is great", but finding it not easy. Another option if you want to enhace your system's performance is look at isolation, component upgrade, room treatments etc. But a tin ear? You wouldn't have come this far if you had a tin ear. You want more because you know you can hear it. Find a way to acheive the goals you have for your music, seek the level of enjoyment that will bring it all together for your needs. It just may not be the cables, sometimes a speaker position can make a world of change. Best of luck.
