Hopefully your findings are easily replicated in the Southern Hemisphere.

Hopefully your findings are easily replicated in the Southern Hemisphere. Remember to put it in the other way round  |

The second purple fuse added to the mains feeding the my mains block
Its not as big of a difference in my system as the internal fuse. It seems to add more body, depth and impact. It has taken a good few hours for the system to come on song again and think it is just part of theburn in process.
At some point I need to do the internal fuse to the Temple superchargers and thats it for me with regards to fuses

Once both are settled in the sum effect is magnificent, though. |

I think I still have at least one more day of small changes to happen but agree as it settles in it just gets better

Has me thinking back to the late 70s and tuning amplifier power supplies using small value resistor(s) in the transformer's primary winding, was a bit of a hot topic.
An awful, awful lot less expensive, with possibly it's own particular sonic merit.

This tweak in the context in my system has probably made the biggest impact of all the tweaks I have tried. The system is the most flowing it has every been. It does this strange thing of improving ambiance, timbre, clout, detail and separation so that the music is just effortless. I cannot really get my head around it how something so little can have this affect,

The linear power supplies I've bought from Aliexpress all have fuses.
Worthwhile upgrading these I guess.
Not wanting to spend £190 a pop on them.
Anything reasonably priced for this task?

If you mean internal DC fuses, I have found HiFi Tuning Supreme fuses to be good and won't break the bank.
For inexpensive AC fuses, AMR Gold are fairly decent.

Do I understand correctly that if the system is already fairly transparent and you have optimized power conditioning, cables, vibration and grounding, then you could also look to replace fuses. So your advice would be that for starters, to replace all AC fuses in the system with AMR Gold ones. Would this be enough to hear at least a difference? If so, it would be worth continuing on the fuse path! Then look for any internal DC fuses on boards and replace with HiFi Tuning Supreme. Finally, for the DAC it is worth splashing out on a fancy fuse from Synergistic Research (Blue, Orange or even Purple). Is this the sensible approach? Martin & John, would it be possible for you to plot out the different fuses in a scatter graph with "perceived audiophile benefit" vs "cost"? |

I have pretty much done all of that. I have now reached the point where all DC fuses in my Coherent PSUs are HiFi Tuning and all AC fuses, both internal and plug, are SR fuses of mixed types, with the best (Purple) reserved for my DAC. I no longer use any AMR but am happy to recommend them based on previous experience. My experience only: | AMR Gold | Small but perceptible improvement all round | | HiFi Tuning Supreme (for DC) | Decent improvement all round | | SR Red | Good improvement in resolution, small improvement in soundstage | | SR Blue | Less improvement in resolution than Red, more improvement in soundstage than Red | | SR Orange | Good improvement in resolution, good improvement in soundstage | | SR Purple | Big improvement in resolution, big improvement in soundstage |

I neglected to say: the almost shocking thing for me (and I think John experienced this, too) is that the step up from Orange to Purple represents the biggest step quality improvement of them all.

Replaced a red more than a subtle improvement

Gustard A22 unnamed internal silver fuse from Eastern Europe: A bit more detail and depth I could hear it but not a significant change
SR Purple More detail depth and musical flow Change easy to hear but took a while to come on song
Furetech power supply (13amp mains lead) to DAC and Behringer
SR red hard to remember how it improved as been in the system some time
SR Purple Another easy to notice change This time more about dynamics bass and sense of scale

Thanks for your views John and Martin.
I have four relatively cheap linear power supplies.
Power for my M2Tech HiFace Evo 2 USB/SPIDF converter/clock, modem, router (and eventually streamer and network switch).
Looking that these power supplies are all around the £80-£100 mark.
Not looking to invest significant money on the DC IEC inlet fuse.
The HiFi Tuning Supreme could work nicely in my situation.
Will just have to sell some things to be able to get them.

On my Temple monos, I use AMR gold fuses. I just tried SR Reds for the last three days. A bit more treble but also a slight edge to the treble that would not go away. The fuses will be going back as not good in my system

I think think the slight treble improvement was down to removing the plugs. But the slight edge is still down to the use of the SR red fuses

Yes, I agree that SR Reds do accentuate edges a little bit. Then again, AMR are nice but a little soft.

The fuses will be going back as not good in my system Are you using these fuses internally (DC) or with the PSU (AC)? I power my Temple monos with 12V batteries - hence the question. |

Definitely don't need the edge
At some point I like to try audio magic but means a big risk as import only
