Audio Horizons Platinum Reference Fuse


Category: Accessories

The audition of these fuses has been a positive discovery in the magnitude of acoustically treating my sound room. My fuse journey began with the original gold Hi-Fi Tuning fuse, then to their Supreme fuse, then to the Synergistics Research SR20, and now to the Audio Horizons Platinum Reference “More than a fuse”. Each change in fuses resulted in an upgrade, at least I thought. It turns out that the installation of the AH fuse has exposed the weakness of the SR20. By comparison it is now too bright in my system; not the “lit from within” nature that the QOL Signal Completion Stage gives but a slight projection of the highest frequencies in front of the speakers, separate from the other frequencies and not natural. The AH fuse is balanced and neutral while offering the best micro and macro dynamics of all of the fuses I’ve tried. I have a PS Audio P10 power regenerator with reference level power conditioners plugged into it for my sources and preamp so I know that my components are getting quality AC power. The significant impact of the AH fuses suggests that the bottleneck in my system has been the fuses not allowing all of the AC power to get to the transformers!!
I had forgotten that my Quad 988 speakers had the gold Hi-Fi Tuning fuses installed. Replacement with the AH model has made them more dynamic and immediate without throwing the soundstage forward. My foot is now tapping uncontrollably. Then I replaced the gold model in my subwoofer that supports the Quads below 63 hz. Incredible difference in impact and articulation.
It was interesting to discover that the AH fuse was not a sonic fit in the PerfectWave DAC or K&K phonostage. The Hi-Fi Supreme allowed the harmonics to come through whereas the AH fuse cleaned it too much which robbed the emotional involvement from me.
I conclude that Joseph has evolved from a Designer who pays attention to the details in his components to one like Lloyd Walker who designs sound enhancing add-on products. I recommend the AH fuse without hesitation for pre and power amps, the QOL Signal Completion Stage, subwoofers and electrostatic speakers. In my system the Hi-Fi Tuning Supreme fuse is better for my DAC and phono preamp which leads me to believe that a good tweak is not universally good for all applications. With a money-back guarantee we can all audition these for ourselves.

Thanks for this. I will contact Audio Horizons tomorrow to get some of these. I have the Synergistic Research and I'm always up for something that will improve the system for less than $500!!!
I suspect the fuse you might want to compare the AH Fuse to is actually the new improved Super Fuse from Audio Magic. Just saying.
Geoffkait and Bazza:
I have a Platinum Reference on the way. I will install it in the PS Audio Power Plant 300, which powers my integrated amp and CD player. I should be able to tell the difference reasonably easily, I think.
My Shunyata ZiTron A digital power cord will arrive tomorrow and then the Platinum Reference will arrive on Friday, so I'll have time in between the time the power cord arrives and the time the fuse arrives to notice the impact. I've been in the Whats best forum and many posters without outstanding systems have had great success with the Platinum Reference.
The most exciting part of all this is that, instead of changing amps ($$$$) and speakers ($$$$$$$) and preamps ($$$$$$), we can make considerable improvements with fuses. For me, its the little things that then allow us to choose the bigger things later on. If a fuse improves a line conditioner and we have out equipment plugged into it, then that's a more pragmatic approach than to go out and spend 20K on an amp, or speakers, or preamp, or source. Changing out my speakers to go to Nola's KO speaker for 10K (which I don't have to spend) makes more sense AFTER I am sure that the wall outlet, star grounded topology and electricity are as completely invisible as they can be. It makes it easier - not to mention more correct in my conclusions - to THEN upgrade everything else.

Geoffkait, tell me about the Audio Magic fuse. I don't know about that. When did it come out and what does it cost and what have you noticed about its effects?

Whatever the case, between the Shunyata ZiTron A Digital Cobra power cord (which Gabriel Caelin, who is posting these days on the What's Best Forum and says the A Digital is going to be superior on say, a CD player, than even a ZiTron Anaconda cord) and the fuse will no doubt advance the system's sense of musicality thru more dynamic inflection and the (required) lower noise floor. I have one of Entreq's units as well, as the piece is astounding, especially for the price. I currently have the Silver Minimus (prefer to start with a smaller investment) and I can tell you it is worth its weight in gold. The more I lower my noise floor, the more music comes thru. The bigger things will take care of themselves.
I MEANT, "many posters WITH outstanding systems have had great success…" Duh...
