Curious, current flow left to right....in an Mains supply which is AC...

I've made up my fuse replacements:  

Hi Neal,

I hope all is good with you. Please can you let us know what you think of the copper rod and any perceived impact on sound quality.

Thanks.

Input to output as you read the label left to right.

Actually - that would only demonstrate that you notice differences when you play with gizmo's.  Although internally we can be happy that we notice a change, it doesn't mean there was a change to notice.  There is just too much research on this, and I don't subscribe to the view that audiophiles are aliens from another planet.

The "Foo Tell" has been apparent for some time on this subject.  That "Tell" that "litmus test" is a collective agreement regarding an improbable phenomena, WHICH IS READILY CAPABLE OF DEMONSTRATION IF TRUE, but nobody ever seeks to properly demonstrate, instead relying on an appeal to faith.  Whilst Mad Moon has carefully covered his back, and only hears differences after hours of warm up and burn in (which renders a sensible blind test all but impossible), MartinT and MikeMusic (and his wife) apparently can hear fuse differences straight out of the box.  Which means anyone wanting to nail this dispute could easily do a blind demonstration where someone changes the fuses randomly without the gifted auditioner being aware of which fuse they are listening to.  DC would point out that the test needs to be double blind to PROVE the fuse effect, and he is scientifically correct, but in my experience at PT, there is no need for such elaborate procedures, since the demonstration will fall at the first hurdle. 

And before the howl goes up, of course there is no need for a music enthusiast to prove anything.  They can all just enjoy what they experience.  But accept that all that PROVES is they experience something, and not offer their experiences as evidence that a phenomena exists.  This saves the need for "its weird isn't it"?  It's not weird - its well established psychology.

My only objection to these fuses is price and the fact that being imported, and no evidence provided of compliance with British Standards, they may be illegal. Actually they may ironically be more dangerous than bypassing the plug fuse in certain circumstances. £130 is far too much to even try and return. I wonder if many customers are plainly too embarrassed and too well off to bother returning them if they hear little benefit.

I have returned things that don't work and would not be embarrassed to return these, too.

I'm just reporting it as I hear it.

Seeing that you feel so strongly about these fuses Richard, maybe now is the time to try one as suggested?

I will definitely be trying these in the future. Got an imminent move ahead of me, so now isn't the time. I've sent stuff back before when it hasn't been an improvement, and I can't see many people keeping a £130 fuse if it didn't show an improvement that warranted the expense.

Where I'm still stuck is in understanding the naysayers who haven't even tried them. Why do they even care? I decided many years ago that tabloids wrre a pile of shite, but I have no interest in trying to stop others "reading" them.

I also wouldn't automatically agree that these fuses cannot be "better" than no fuse at all. Gazjam reported they were better than a copper bar and I look forward to trying that experiment myself at some point. If "no fuse" is better, then I will use "no fuse". If the quantum fuses sound better, I will say so and buy more. As I don't know how they affect signal or perception, I make no assumptions either way until I try.

Naturally BS kite marks are of no interest or relevance to me, but if I lived in the UK I wouldn't give a shite about a kite mark. They would clearly perform their designated job of protecting the cable. The specs are thre to be seen.

The part I find funniest of all is that the manufacturer and retailers are getting so much free publicity as a result of the debates fuelled largely by the detractors. They must be in stitches!
