I recently added the aforementioned fuse to my Wireworld 6 way distribution, after adding a number of Belden mains cables, note the Wireworld feeds only my Router, Switch, Fibre Bridge, TV and Sky box, the Nova is sited away and is powered off another mains outlet.
This is the reason I posted this on the Streaming thread.
The SR Blue Fuse has had me overwhelmed for quite a few days now, is has an steady break in, but to me the best way to describe the improvement is like major amp upgrade.
Again bear in mind the Fuse is not directly near my Nova, only the Ethernet is the link.
I have had to drop my usual listening volume by some margin, as the sound is so wide, the bass has gone an octave or few further, but very taut, tuneful bass, just so much more.
The level of detail is quite shocking, but to be honest overwhelming after a while, initially is wasn't so bright, yesterday it's was just information overload, today much more fluid.
My main point here is a very simple change not directly to the Naim gear, is bringing substantial improvements.
The fuse is apparently on 30 day return policy, so nothing to loose, just hoping the break in ups and downs smooth out, I've heard from the person who recommend it to me, it just keeps getting better, if that's the case for yes a shocking price for a fuse, this is an amazing upgrade, that's IF it settles.
Either way the fuse will stay as the improvement it has brought to my TV is amazing.

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.
I have essentially the same view regarding “burn in”, though not absolute, in that I recognise that some electronic components can change slightly with heating/current, either permanently or reversably so affected every time the gear is turned off or low current standby (though the reversal of that should only be the time to het back up to operating temperature). Some components also change continuously with time, accelerated with higher temperatures, until they reach the point where their change has made a marked difference to performance (e.g. needing re-capping) or even fail completely.
... But not a piece of wire, at least not unless i) it is significantly under-specified for the amount of current it has to take so that it gets very hot in use, which might be a concern for other reasons and certainly can never apply to interconnects, or possibly ii) cryogenically treated wire, which may have undergone crystalline changes with the extremely low temperature - and might then reverse over time when used at or around room temperature.
With reference to the first paragraph above, unless the affected components are unsuitably rated for the heat environment, such changes as may occur should be small and the effect on sound also small - and I am at a loss to understand the ‘yo-yo’ uo and down effect people talk of.
I am, however, aware that my own ears are not identical all the time, and can change either over a period of time - which may be days (I have no idea as I have not attempted to measure their response) - or instantaneously as with a yawn, a sneeze or blowing my nose, the instantaneous change yielding a distinct change in how things sound. And I am aware that my memory of hiw somethings sounds is not a fixed absolute, so I cannot really tell if something sounds the same or different same weeks or months later, whether it has been a gradual change or if I have simply not listened in between, while I do know that the human brain is adept at learning, which can include becoming accustomed to something and thinking it is normal, or learning to like something that at first wasn’t liked. An example of gradual change going unnoticed is as equipment ages to the point that re-capping is undertaken, with then a sharp change in performance that is insyptantly and clearly heard.
This does not negate what some people say they hear with ‘burning in’ of things like wires - when you take into account the fact that hearing is a combined ear and brain function: One’s brain telling one that the sound has changed over time is actually no different from ones brain telling one “OK, I have got used to that now” (or whatever), it’s just a different recognition or interpretation of the actual facts.

It seems to me the technology in this little blue fuse is a graphene coating around the fuse’s conductor material.
It’s high tech stuff, and a great British Discovery at a Manchester University by two students who later won the Nobel Prize for Physics because of their work.

I think im going to take a punt on one, if there’s no appreciable improvement, then take them up on their money back guarantee and just send it back.

Hi Obsydian
Ive found they’re for sale on the mcru site, £130 a go, have you seen them anywhere cheaper by any chance.
I’ve just got a new mains cable for the Uniti Star and 6 way extension off them, I didn’t go mad price wise, together they cost £120 inc delivery, there is a slight noticeable improvement from my Uniti Star and a much more noticeable improvement in the picture quality on my TV that I wasn’t expecting, just seems sharper and the colours mote vibrant.

I’ve just ordered the SR Blue Fuse, £120.50 with 10% off plus delivery.
Got so many things I want to try it in, think I’ll put it into my extension feeding all my HiFi gear, then try it in my Nova alone, this time last week I had a Star, that’s another story but what a difference, the improvement over the Star is massive.
Just hope it lives up to expectations.

I would start with the Nova and not swap around until at least a good 150hrs run in, with the Nova that means keep it out of standby or playing music 24/7 to speed up matters. There are quite dramatic changes/shifts, if you swap before it is "stable" you can never assess the true impact or may decide it is all boll##ks 
I started with the SR Blue into my Wireworld 6 Way (feeds my Router, Switch, Fibre Bridge, TV, Satellite), then 2 weeks later the Nova.
Remember the SR goes at the top of the fuse holder (hot end)

If it is subject to ‘burn in’, stick it in something non-audio that is on 24 hours a day for a few days, then you can do simple A-B comparisons cleanly.
In hindsight i was impatient and just wanted to get to burn in (they quote 200hrs), main driver for that was at 50 hrs or so it went downhill and the daily shifts (majority up, some downs) was interesting, but averaging 3hrs a day was taking a while, then i realized the Nova on standby basically draws next to zero power.
I would (if you can bear it) let the process take as long as it naturally takes, i was focused more on returning it within the free trial, so that was also a driver to maybe consider.
Without leading Anavrin, you need to think very differently about this upgrade, as you may focus on minor changes you are familiar with and then miss everything else (big changes), i only realized when i went back to 2p fuse. Also DO NOT change anything else (speaker position due to bass), let it settle.

I should put it in one of the extension leads that feeds the kids games consoles that should break it in fast, or maybe the tumble dryer the amount its on in our house!
I only just had my Nova for a week so that’s going to change in sound too I guess.
I think the acid test will be the “real” reason I bought it, which is more work related, I’m hoping it will improve the image quality on a sensitive peice of medical imaging equipment, this is something I wil be able to measure, but I wouldn’t want to try it unless I had a fully run in fuse first.
Sounds like hard work but should be exciting to hear what these little jobbies contribute.
