We Need A Separate Forum for Fuses
geoffkait - the notion of diretionality means to favour one direction over the other. If the current travels in two directions, there is no favoured direction, therefore directionality becomes irellevant, hence my use of the term 'indirectional'.M...

A better term would probably be indirectional, as there is no directionality.Either way geoffkait, can you elaborate, as I fail to see how a fuse carrying an AC current can be directional.Thx

geoffkait - how can a fuse in an AC circuit be directional? AC by it’s nature is non-directional. Please elaborate. Thx

Shadorne - your comment above is why I chose to leave AC power fuses to one side. The problem here is that fuses are being discussed in three different contexts - I think you hinted at that above:1. DC Power Fuses2. AC Power Fuses3. AC Signal fuse...

fuses are NOT supposed to be affecting the audio signal .and if the are, you have a problem someplace.

Just because is costs 30 grand, doesn’t always mean it’s any good

"I am certain that for this kind of money a completely new and well designed power supply could be installed in the users problematic equipment."Right on!

trelja - the fuses in a speaker are going to be operating with a valiable voltage depending on the volume, so they will, as I suggested in my post above, be skirting very close to their blow point at times and will therefore be prone to dissipatin...

Seriously though, if there was a resistance in your fuse, there would be a voltage drop accross it, which would adversly affect your equipment and comprimise it’s design.Fuses are designed to only dissipate heat (and therefore present a resistance...

geoffkait - last time I tested a fuse for resistance, I think the value on my meter was 0.000 ohms.

Given the relative length of a fuse’s wire to that of a 5 yard speaker cable - let’s say 1:500 - I’d wager that a fuse would have 1/500th of the effect on the sound of your system than a cable can, assuming you believe cables can make any discerna... 
The ups and downs of tube vs. SS...
Solid State vs Tubes. What about Solid state 'with' tubes?By that, I mean hybrid amps, of which there are a few out there and I am in the middle of building one myself; it's sounding very nice.The idea of a hybrid is to use tubes to amplify the sm... 
Curious How These Nordost Speaker Cables Do What They Do
Blimey - that’s a bold statement by a manufacturer:"Although the cable signal is an alternating current, small impurities in the conductor act as diodes allowing signal flow to be better in one direction over time. This effect is also called quant... 
Thinking out of the box here. It might make some defensive

Do I have to brand match preamp and amp?
The only thing you have to match is the output impedence of the pre-amp with the input impedence of the power amp. The input impedence of the power amp needs to be at least ten times the output impedence of the pre-amp. The ratio can be higher, e....
