Fuses
I’ve read of views on whether amp fuses impart any sound quality or coloring. I had a recent experience that has made me re-think my views (fuses do not affect sound) and wondered if others had a similar experience.
I have a Line Magnetic integrated amp. After heavy regular use for over 5 years, one day it just wouldn’t power up. After checking the power supply, I assumed it must be a blown fuse. I recalled that Line Magnetic sent with the amp two replacement fuses of the same type/quality that was pre-installed. I dug out one of them from storage, replaced the fuse and the amp powered up normally.
What surprised and delighted me was the change in sound with the replacement fuse. Fuller bass, more detail and more warmth. I have rolled the tubes several times in the amp, and am attuned to the subtle changes that can make. Popping in a fresh fuse seems to have had a similar affect. And these appear to be cheap fuses, available for a few dollars at most. I don’t think I understand any of this.

I fail to understand why some insist on repeating the same old tiresome put-down. You don’t wanna try because you KNOW fuses can’t affect the sound so move on. You can perhaps spend the time listening to music unless your system just does not entertain which would not surprise me. Here’s what to do: Post a list of your components for all to see so that open-minded, experienced and helpful members can offer advice on where you went so WRONG. |
@MC, when you selected the Path resistors had you made any comparisons with the likes of Duelund or Mundorf? I have tried some different ones and settled on Powertron by Vishay. Rated at 3W or 30W when mounted on a small heatsink. Clean, detailed and very dynamic but have not compared them to the 3 mentioned above. It seems even experienced DIYers seldom bother with resistors which I find surprising. https://www.hificollective.co.uk/catalog/powertron-resistors.html The Powertron may also be causing an upper midrange glare. I have little time at the moment to experiment further not to mention the mess changing caps makes to a carefully constructed XO. |
Hey mitch, I will look into that as soon as I get a little time to think. Right now we have 4 or 5 days dry weather ahead so wife and I are trying to finish off some house repairs before the cold wet stuff really sets in. I bought a leaky old Irish cottage which is playing hell with my audio life and the damp has wrecked 2 power amps. @OP, apologies for going off topic. |
@grannyring, that's exactly the info I was looking for. They have an uncanny sense of ease to themI then do not need the Duelund's influence going by what you said. I use Mills a lot as I find them a 'safe' resistor to use but as always, looking for and hoping for something great but at a lower price which lead me to the Powertron. The Path are twice the price but my XO only uses 2 per side. I have long tried to reduce the number of components in my XO designs by eschewing the industries fixation on a flat frequency response which inevitably impacts on other more important areas, and when you add the room's response then the life-sapping extra components are pointless, except if you need your creation to pander to the measurement brigade. When I have managed to find driver sensitivities that match and allow me to forego any resistors, I have found the result to be more 'comfortable' and more immersive. Oh, and to keep this on topic, I do not use FUSES in my crossovers 😎 |
