There are many reasons why someone might not get the (excellent) results most other people report or might only get minimal results. This sort of thing actually happens with almost every audiophile device and even with cables. There is never a guarantee of 100% reproducibility in this hobby. I suspect with fuses especially, you know, what with the directionality issue and long burn in times, it’s mighty tempting to blame negative or null results on one or both of those particular things. But there are other reasons, too. George Tice, in his letter to Stereophile regarding a particularly angry response from a dissatisfied customer of his Tice Clock, proposed four reasons why audiophiles sometimes don’t get the results they expect from certain audiophile products (like the Tice Clock). And I quote,
"There are four reasons why someone could not get the full potential from a TPT Clock. They are: 1) You did not follow the directions. 2) There are one or more choke points in your system (a choke point is a component which is significantly below the quality of the rest of the system). 3) Your audio system is not up to the standards by which anything can be accurately judged. (I noticed in your letter you never mentioned what components you use.) 4) Your hearing ability is not as refined as that of other music lovers and audiophiles."
