Fuses that matter.

Every electrical part in every component has specified and/or measurable ranges of variation ("tolerances")

Why raise the point in the article if the measurements are less than tolerance level?

Why raise the point in the article if the measurements are less than tolerance level?

Several reasons come to mind:

1)As I and Kijanki indicated, whether or not a given tolerance for a given parameter is sonically significant will depend on the design of the specific component in which it is used.

2)For a specific component design, a specific part, and a specific parameter, the line separating tolerances that might be sonically significant from those that are overkill will often be a gray area, about which opinions can differ. Obviously the designer of the particular component is in the best position to make those judgments (which is not to say that he or she will necessarily make them correctly).

3)Perhaps most significantly, my perception has been that it is EXTREMELY common for audio-related white papers and marketing literature to cite and describe technical differences without addressing in a meaningful way whether or not those differences are QUANTITATIVELY significant.

Bryoncunningham, does it matter which is true? I think not. To each his own. None of this discussion matters much to me. I am merely stating my experiences.

Every electrical part in every component has specified and/or measurable ranges of variation ("tolerances") for numerous electrical parameters, and measurable differences will exist even between two parts of the same type that were manufactured at the same time by the same manufacturer. That applies to transistors, tubes, integrated circuits, resistors, capacitors, diodes, inductors, transformers, fuses, etc. A good design will minimize or eliminate sensitivity to those differences, within the range over which they can be expected to occur.

Even if parts from different manufacturer that measure the same, will sound different in most cases. A Sovtek tube will sound different from a Amperex? Mundorf and Duelund cap? Possibly a Radio Shack fuse and HiFi Tuning in some components/systems??

Even if parts from different manufacturer that measure the same, will sound different in most cases.

Agreed, of course. But that does not mean that parts which measure different in some respect will necessarily sound different, which was my initial point. As I said, it depends on the amount of the difference, and on the design of the component in which the part is used. And of course on the type of part, the function it performs in the particular design, and on what parameter is being measured.
