things do sound more vibrant,including my plasma TV picture, which is plugged into one.

If I can get my tv picture to sound more vibrant . . . sign me up.

Possibly referring to those TVs that now use the screen as the speaker as well...?

TV with screen, I found the same, picture and sound ????

I meant the sound of my audio (Naim) and PICTURE of my plasma...

7 days on and to say the plug fuses have transformed the Nova is an understatement.

Interesting returning each time to listen the sound constantly evolved, more grown up, authority, control, detail.

Like I said before like a major amp upgrade, but would now add pre amp to that.

To give a reference I went Atom to Nova, I would say that was like a 20% compared to what the SR Blues have done.

Anyone care to give a possible plausible scientific explanation for the improvement?

I find this thread really interesting, I’ve just bought my first couple of mains upgrade products for my Uniti Star in the form of a new mains lead and audiophile grade 6 way power block, I’m hopeful the Belden cable in each will be an upgrade over the Power-Line Lite and my cheapo 6 way extension, now I’m thinking next month I’m going to be trying one of these blue fuses on the 6 way.

Especially if there’s a money back option if your not happy with it.

I do wonder though, is this fuse better than no fuse? Is it possible it’s adding something that wasn’t there or do normal fuse’s take something away?

Hi Anavrin, i personally did not like the Belden on the Nova, i did test a Belden purely as it had the SR Blue Fuse fitted, so was an easier swap over. For me on Naim, Naim cables are best, my only exception to that is Chord, but all this can be a personal preference.

No fuse, over a decade i did try that with a 15A plug (round pin UK, it has no fuse) into a 6-1 Hydra, it was good but nothing like the SR Blue.

I tend NOT to read reviews before, as i like to make up my own mind first, but if the change is good, i do read up, so found this statement from SR blurb - "through Inductive Quantum Coupling methods we collectively call UEF Tech. In fact, UEF Tech is so powerful even an electrical chain several miles long is fundimentally improved with nothing more than a single fuse engineered with our patented UEF Technology.

Inductive Quantum Coupling sounds like Voodoo to me I'm afraid, what type of fuse in standard in the full fat Naim Powerline?

Inductive Quantum Coupling is actually very easy to explain and illustrate:

Any moving electron (or other charged particle) exerts an influence on every* other charged particle through magnetic coupling.
This occurs because a moving charge generates a magnetic field proportional to it's charge (a quantised value) and it's velocity.  In a medium of consistent relative magnetic permeability the strength of this magnetic field decreases with the square of the distance.  This field causes a force to be exerted on any charged particle within the field; this force is proportional to the influenced particle's charge (another quantised value) and the field strength.

Illustration of the use of this: a transformer.

* limited only by the limitations imposed by the propagation speed of the magnetic field (inversely proportional to the square root of the product of permittivity and permeability of the medium in which it is travelling; in vacuo this is equal to the speed of light).

Hi MERCKY - agree for a lay person like me its Dutch, but clearly HUGE understands, for me the proof is in the sound, but as always this should be treated as possibly a personal preference/setup dependent, but for a 30 day trial, I thought worth a dabble.

Hi Obsydian, I think you misunderstood.

Inductive Quantum Coupling applies to inductive devices, not to fuses.

In electrical terms such as inductance etc., fuses are essentially just a short piece of resistance wire... unless they've done something really weird such as winding it into an inductor!  In which case a normal fuse with a small inductor in series will have the same effect.

Maybe this fuse manufacturer could usefully apply your words in its advertising, using them to explain unequivocally how Inductive Quantum Coupling enables their design of a short conductor that is designed to melt, vapourise or otherwise rupture under closely specified current.time conditions to improve an electrical chain several miles long, compared to either a conventional melting or vapourising short conductor (or indeed a continuous conductor capable of carrying a much higher current without melting, vapourising or otherwise rupturing).

An rf filter!

Don't forget that magnetism is a long range effect...

So an electron moving in one conductor will influence an electron in another conductor 1000 light years away.
(OK the effect will be almost infinitesimally small and will take over 1000 years to start acting, but it'll eventually get there none the less!)

The mains DM mutual inductor I use is 60mm∅, 50mm long 18 turns of 2.5mm wire each side, with an inductance of 10μH each side.
Even that amount of inductance only has a minor effect!

What you are suggesting, IB, is that the manufacturer should come clean about his products, in this instance, the old 'Inductive Quantum Coupling' routine.  A clear explanation of what they are marketing to us would effectively cause their sales to drop like a stone.   Their market place is chock full of people who live to brag (or post) about their latest upgrade which is based on such complicated science as to be totally baffling to everybody who might venture to inquire about its workings.   And if it's baffling and very  expensive, then for this particular band of hifi pioneers, then it must be this month's holy grail.  So please don't exepct to see any unequivocable clarity any time soon  (unless it's the Trading Standards office taking an interest).

Mind you, it's only half a lifetime ago that I wouldn't have considered anything but bell wire to connect speakers to my 'hi-fi'.  and, as for spending three thousand pounds on a single interconnect, that would never even have entered my head.   And £13,000 on a streamer? 

  Oh, the power of advertising.

I thought the forum is to post experiences, or is it exclusive to just those wanting to gain self esteem or ego points and say hallelujah to anything Naim at any cost, especially with a remote someone called laughable ???? but £13k for that is fine...

I'm sure no-one is disagreeing with you that you've got an audiable improvement to your system's sound, or aiming any criticism at you personally, but they are questioning the reason, as given by the supplier, as to why there's a the difference you report. The "tech speak" used as the marketing description is not correct electronically for a "fuse" as we know them. The words chosen to market the device (or devices, as it isn't limited to this one supplier and a few fuses) already have meaning and can't just be thrown down as a "scientific" description because they look or sound good - they also need to make sense as per their dictionary definition and I think it's for this reason that there are many incredulous contributions to this thread.

There are some very clever people who are members of this forum who want to know how this works to produce the changes you've heard and continue to hear, but the supposedly technical descriptions given by the supplier don't meet their knowledge of what the phrases used mean as applied to a "fuse" (should we be calling it a fuse for example - is it actually a more complex device as someone suggests above?). It's not really for them to examine the device to find out what it is, what it contains and try to work out how it works - it's much easier to say snake oil than invest that time, effort and outlay. The supplier could use clear, precise, language to describe the device if they so choose.

Leaving aside whether I believe it make a difference or not, I don't understand how it could improve over time surely when you get down to it its a piece of what, half mm thick wire by a cm long, its not going to take long to 'burn in' surely?

Hmmmm, time for a new thread, perhaps - do short cables burn in more quickly than long ones?!

FWIW I dont really believe in burn in except for speakers, i.e. new speakers loosen up over use to settle on their signature sound. To my ears hifi electronics sound as good as they will a few minutes from turn on.

Well my 552 certainly evolved over its first few months... and it wasn’t all about getting better.. it had up and downs  and then ultimately mostly stabilises. I agree there are many possible causes of ‘burn in’, including cables and connectors becoming mechanically distressed

Of course  Huge.. it depends on frequency, at 1GHz, even 10uH is going to have an appreciable reactance effect of 63 ohms...... but I agree the amount of 1GHz causing audible interference will be minimal unless it’s modulated to produce intermodulation sums and products.

I was referring to perceived effect, but yes, I should have been more specific in my wording.
