Fuses that matter.

Is fox news biased?

How about cnn?

These are major providers of news to millions.

So yes it is quite possible.

Mapman, you say, "That would include the user thinking he heard a difference, not just factors with the electronic equipment. That can clearly be a factor." Sorry, I cannot agree to that as you are making an a priori judgment. I don't "think" I heard a difference, I did. You perhaps only think you did not hear a difference.

I only use slowblow fuses in amps normally but IsoClean only makes slowblow fuses. Surge current is the reason to use slowblow. I guess were you to have a massive preamp power supply one might be needed there.

That is an excellent example of a Strawman Argument. It is illogical to argue that because a news station is biased that all tests of an audio device or component are biased. I suppose that is a skeptic's wishful thinking. As I already pointed out, nobody is saying (expectation) bias does not exist in audio, it's just that bias can be eliminated as a culprit (by care in testing). Besides, the type of bias that appears to apply in this case is actually negative bias, since most skeptics like yourself and others are predisposed to believe the fuse cannot possibly work. You won't hear it because you psyched yourself out. Lol

Geof,

As a vendor of controversial tweak audio products, is it reasonable to think that you might be biased?

When i start my audiophile fuse business and bring the funky little fuse to market, i will likely become a member of that club also if you would have me.

Actually, I am not biased, not in the sense you mean. I am actually quite objective and scientific. I have a sneaking suspicion you're not quite ready to be a member of that club.
