Thanks, I didn't know Stan had his own line. I've got quite a few spare Bussmann fuses having replaced them with upgrades.

Got them plumbed into the capella/caiman-not night and day but a noticeable difference in attack and crispness( if that makes sense).
Have only tried the main rig- onto lates tomorrow so will have a listen on cans whenever I get finished.
Well worth a tenner IMHO.

When I received my new Coherent 6D power cable, it came with a stock fuse. This gave me an ideal chance to try the three 'hi-fi' fuses I have at my disposal. For non-UK readers, these are the 25mm (1") fuses used in our mains power plugs, not the typical 20mm or 1¼" chassis fuses used in some components. Nevertheless, the findings should be similar if the fuses are available in your local size. Remember that the 6D feeds my regenerator, and therefore the entire system, so it's the most important fuse in the chain for me.
The stock fuse was a Marbo, and the three specialist fuses I tried are a Russ Andrews original (£25), an AMR - Abbingdon Music Research - Gold (£15) and a Hi-Fi Tuning (£35), all 13A rating.
I've used Russ Andrews fuses in all my power cables for many years in the past, having felt that they gave a useful uplift in overall sound quality over stock fuses. Difficult to put a finger on, as the effect is very subtle, but improved transparency and 'cleanness' to the background are features. Putting the Russ Andrews first into the 6D and giving the system a little settling time, I found the same very subtle enhancement to the sound. Better than stock, and good value for money for a single fuse, but perhaps less so for an entire system.
Moving on to the familiar Hi-Fi Tuning fuse (I've been using it in my previous MCRU Ultimate HC cable), there is another more significant uplift in sound, giving better leading edge detail, more space to the soundstage and more micro-dynamics. Music springs to life. This is a good fuse and I am not surprised at the result. A couple of examples: Ry Cooder's The Very Thing that Makes You Rich starts at almost dead silence and builds to a very busy and exciting sound, with vocal harmonies backdropping some excellent percussion and guitar picks. Just wonderful, and sounds very alive. Van Morrison's Haunts of Ancient Peace features a very raw voice but the most vivid and beguiling sax I've ever heard, not to mention the fantastic slapped/plucked bass. A great performing fuse, but not cheap.
Finally, I put the AMR into place and gave it a similar settling time. Well, I'll be damned; it sounds as near as dammit to the Hi-Fi Tuning that I can't really tell the difference. This is a brand new, never used, fuse too. Soundstage: check. Micro-dynamics: check. Fine detail: check. It's all there, and the Ry Cooder and Van Morrison sound as wonderful as before. That makes the AMR extremely good value for money and way better than a stock fuse. I shall keep listening to it to see if it improves at all over time. Highly recommended, at least for your main feed cable.
Hi-Fi Tuning website (and if you can make sense of it, well done). AMR website.
  
Our standard warning about mains power components applies: if you don't know what you're doing, then get a qualified electrician to do it for you. And never, EVER bypass fuses: they are there for a reason. Some eight years after you posted this review. It is exactly what I was looking for. The Russ Andrew’s fuses have been recommended to me, but I wanted to know how they stack up. Bing! Here is the answer. Reading online I see the SR Orange or Purple seem to be the target fuses, but I need 15 so wanted to start by changing them all in one go, then work through with SR fuses. AMR fuses it is as I can do the whole system for the price of two SR fuses. Based on the other comments in this thread I’ll start with an SR in my condiftionet and move forward from there. |

That looks like a sound plan, it will give everything an uplift and the sum effect will be significant.
If you have one power distributor or filter or regenerator feeding the whole system, when you're ready put an SR Orange in it.
For your most significant digital gear, try an SR Purple.
All these things can come in good time. Meanwhile, enjoy the AMRs.

I did just that with SR Orange and even after a quite some hours I ended up taking them all out again. I have since swapped (one component at a time) to HiFi Tuning Supreme3 Copper fuses and much prefer the end result.
That is in the German system and that only has one UK plug/fuse (for the sub from a UK socketed Titan) which does have an SR fuse it it and which I will change to the Orange I have following a comment Tony made (the Titan feeding the power amplifiers is Schuko). I have started the same process in the UK system and intend to use the HiFi Tuning fuses in the rear panel and internally (fast blow are hard to source in the UK I find, but easy in Germany) and will convert the Gordion power conditioners to Schuko outlets thereby eliminating the fuses in the plugs. The cables from the wall outlets to the two Gordian units and the Titan will get SR Orange fuses, but the cable from the Titan to the power amplifier will get a HiFi tuning fuse.

I really like HiFi Tuning fuses for internal DC power supply rails, where fused.

I had a Krell Kav300i integrated amp a few years back.
I swapped all its fuses(7 I think) for Hifi Tuning and it made the amp much smoother with better bass.

I wonder is that to get us to buy thinking we don’t need to swap all our fuses, knowing that once we hear one, we’ll be hooked? |

Reading between the lines, the Master Fuse appears to be a no-compromise detail extractor. That tells me that, in numbers, they could make your system sound harsh. Experience tells me that searching for resolution in digital systems always requires a re-balancing of the system to prevent brightness.
It sounds like the Master is a Purple on steroids. I even balance my Purples by using Oranges in the regenerators and other components. Buy with care!

That's why it is imperative to match and balance things in your system.
The purple fuse throws my and a lot of our clients systems way out of balance.
I use orange from the wall on the dual feed to treatment plant.
If I use a single purple in the lps it really turns the system into naim experience and that's just one purple
Conversely some customers really embrace the purple and it works for them. If you have a warmer and more safer type of sound then the purple will allow you more detail and slam
The new master fuse is 600 imho that's not a tweak I have some coming so will throughly test them
I only use two SR fuses in my system, the rest are very different.

I will wait awhile before thinking about it
The price is a good reason to delay too

I’ve just ordered an SR Purple for my Dac. I’ll see how I get on with it before ordering any fuses for my speakers.

The SR Purple fuse for my Dac arrived today.
It improves over the SR Blue right out of the box. Reverb’s go on forever.

Excellent result, Matt. The Purples are great in my DAC and DDC.

Oddly enough it really screws up the DDC's here and over eggs the dac into naimdom.
Though with the Grimm MU-1 it really helped no end, turns the Aurender N20 into a very odd sound, but that may appeal to a few folks.
If your a blood and thunder appreciator or have a Jazz cats system then Purple may well tick your box

Has anybody heard the Master fuse yet or tried the Audio Magic M-1?
