And this is not correct, as a mains cord because of it ’s construction has very different set of parameters to it’s length, it has resistance, capacitance and inductance.
A mains fuse as none of these, save for "maybe" a very minute (milli-ohm) amount of resistance, which means nothing. And could be regarded as differing ambient temperature when measured as Ralph or Al pointed out very early in this thread, when the milli-ohm resistance measurements were quoted as being "the reason for the massive sound quality improvements".”
>>>>Sorry, George, you and Al and Ralph are incorrect. Not even close! Nobody, especially HiFi Tuning, ever claimed the resistance measurements provided in the Data Sheets are responsible for the relatively large changes in sound observed by listeners. In fact, they say the OPPOSITE. Hel-loo! If any of you had ever bothered to read the HiFi Tuning data sheets, you would have seen that HiFi Tuning states UP FRONT that the very small measured differences in resistance do not (rpt not) account for changes in sound quality from fuse to fuse and from direction to direction they heard. So, obviously there must be other (unknown) factors are involved here besides resistance. And as I’ve oft stated, the HiFi Tuning Data Sheets resistance measurements PROVE that fuses are NOT symmetrical as naysayers would have us believe. And more to the point - the small resistance differences do not prove that large differences cannot be heard.
To whit, from the HiFi Tuning Data Sheets,
”The measurements done so far showed some measurable differences between fuse,
but didn ́t explain completely the sonic differences between fuses. One way to look at these phenomenon’s is, that music, containing many pulses can be limited by the electronics being in the reproduction chain. Fuses with better contact material (e.g. no corrosion) and overall better make will limit these pulses less. Another way to look at the problem is: like any wire or resistor fuses produce some thermal broadband noise. That noise depends mostly of the material used. The thermal increase of noise was measured at a current of 0,1 Amp. DC and the increase is given in dB.”
