Hifi Tuning Fuses

"More than subtle with no down side." Is my impression to a "T".
I tried one first in a Wadia 64, then had a fuse blow in a Krell Power Supply. It was doubted if it would be a benie there. I tried it during a sale early this year. I have since tried it on CD, Amps, and A/Ds without a single regret on a smaller and smaller audio budget.

Douglas S. - Note past tense; emphasis on "HAD been very skeptical....". I've definitely come around in my opinion about cables. No opportunity to do A/B testing where I am but based on reviews (I have found TNT Audio to be really helpful) and affordability, I upgraded some very old Monster speaker cables to JPS Labs Ultraconductor. Also purchased a Superconductor FX interconnect for CDP to amp. Those changes made a big positive difference in my system. Made a DIY power cord using Marinco parts and Belkin(?) 12 gauge cable following a method at the PartsExpress site. I'm less certain what impact if any this has had. But directionally, it can't have been a step backwards. Power conditioning is something I'm interested in but it seems "pricey" to me. The HiFi Tuning Fuse came after the cable upgrades and confirmed to me that given the ability of other components to support some necessary minimum level of resolution, other seeminly "minor" system changes can have a strong positive effect on sound.
(I'll check out your article). Thanks for the reply.

I found the HiFi fuses to be a nice improvement. Not as much as upgrading the power cord but about as much as changing an interconnect. Go for it!

I agree that HifiTuning Fuses definately improved the performance of my preamp to a new level;more detail ,more liveliness.I also noticed changing the polarity of the fuse by turning around also helps to change the sound,have fun experimenting!

HiFi tuning fuses do make a difference. However that difference may or may not be for the better. I have replaced fuses in my PS Audio P600, ARC 100.2, ARC LS12, ARC PH5, Magnum Dynalab 106T, VPI SDS, and Martin Logan Depth Subwoofer. The fuses improved the sound quality in the Magnum Dynalab tuner, the Martin Logan Depth Subwoofer and the VPI turntable. The fuses did not improve the sound in the PS600, or any of the ARC equipment. The fuses changed the sound of every component but not always for the better. Be careful.
