HiFi tuning fuses, some benefits help

I haven't tried them, and I don't intend to. Therefore I won't express an opinion about their performance. But I would suggest that you consider the following:

1)It would stand to reason that in some fraction of the cases where improvements were noted, the real reason might simply have been that several year old fuses, whose surfaces were dirty and oxidized, were replaced by new fuses with clean (and oxidation-resistant) surfaces. It might be worth first evaluating your existing fuses after treating them with a contact cleaner.

2)It would seem pretty clear that the differences, if any, would be dependent on the design of the power supply in the particular amplifier or other component. The more ideal the power supply, and the better its ability to store and deliver energy to cope with transient peaks, the less the difference the fuse figures to make.

3)Similarly, the narrower the dynamic range of the music you tend to listen to, the less difference the fuse figures to make, imo.

Compared to the cost of so many other "audiophile" tweaks, $30 is pretty inexpensive and worth an experiment if nothing more. I tried the HiFi Tuning Fuse in my relatively low cost/entry level system. It made a difference in the JoLida 502B I was running. When, at some point, a tube went and took the HiFi Fuse, I didn't have a spare so had to replace it with an inexpensive RadioShack fuse until the new HiFi fuse arrived. For me the proof of what the HiFi fuse did was in the loss I heard when it was gone. Something was definitely missing. Presence? Liveliness? I have a hard time articulating the differences in sound quality but to me Rodman's description fills the bill. For the skeptics, I'm not at all concerned about convincing you - believe what you will. In turn, spare me your sarcasm (especially if you haven't tried one of these). I heard a benefit well worth $30. That's all that matters.

Ghosthouse,
I have a pair in my system. I can't tell you specifically how my sound was that much more different for having them in place. Excuse my attempt at "irony" in my last post. It really was a "whim" purchase with no great expectation. I'm glad the fuses sounded good in your system. Take care and enjoy the music.

I replaced the 3 fuses in my Sugden A21 and really didn't want to hear a difference because that means I now would need to replace fuses in many different pieces. So I always err on the side of cynical. However, I really did hear a more open presentation and cursed my future purchases. Same cynical approach with power cord upgrades was met with a mixture of appreciation and resignation to more investment.

For me I heard more details. The increase in details for the bass is quite obvious.
