Determining current flow to install "audiophile" fuses.

TO: jsbach1685
I installed 4 synergistic research red fuses in my Odyssey Khartago
extreme and the results were awesome. Each fuse cost about $90.00. This
has been the most cost effective modification I have ever made without having to use my soldering iron. It is my intention to call Klaus and tell him to offer these fuses as on option on new units. He should also put them in demo units at shows so that everyone can hear the true potential of his amps. Synergistic research has recently started selling black fuses (with
even better sound) for $120 each and I will be be upgrading to these black fuses soon.  Have a look at "synergistic red fuse" in the Amp and Preamp forum. I have no connection with Synergistic research and the only reason I am making this post is that I am a fan of Odyssey power amps.
Good luck

Wow!  Well hot dog those must be some truly brilliant pebbles even if you must say so yourself! 💥

Fuse directionality is not something exclusive to only high-end fuses. I found that even cheaper fuses have a preferred direction. One way to find out is to look at the cap ends with a magnifying glass. I found that the majority will have the power rating stamped on one end, and the other will usually have an assortment of symbols. Yes, I found the OEM fuses even sound better in one direction, but not the same as the high-end ones. I have the Hi-Fi Supreme fuses.   Before plunging, I tried ceramic fuses of the same rating as the OEM. They sounded a bit smoother than the OEM. I simply diagrammed on a paper the direction using the cap's indicators. So far, its been consistent for each fuse. They key is, one direction will sound smoother in comparison.

What you are most likely hearing is the warm-up of the unit after its been powered down in order to replace the fuse. I think you will find that this is repeatable, regardless of which direction the fuse is installed. This is an excellent example of expectation bias.

No, actually it can’t be expectation bias or warming up of the component, inadvertently scraping off the dirt or oxide from the fuse holder or even placebo effect. We’ve already been over that. You can easily eliminate those possibilities through careful testing.  It’s due to the non-symmetrical orientation of the crystals in the conductor. I can provide a paragraph describing the Backfire Effect if anyone is interested. No strings attached. Ironically the reverse expectation bias might actually explain why some people can’t hear directionality.

Well actually it totally can be; just because  'We've already been over that' (which 'We' haven't by any means) does not make it so. Some more gullible types might be taken in by that though.

Occam's Razor applies- the complex explanation being the one you often give; expectation bias or warmup- both being **much** simpler explanations.

Otherwise simply must be ready for the sale on bridges in Brooklyn.

Just in case there is any issue here- most of these fuses are simply gold-plated versions of exactly the same fuse that you can buy off the shelf. The element does not get treated- its the gold on the ends that gets added. So there is no mechanism to allow for directionality.
