In fact I have tried many.. Isocleans are good, Hifi tunings might be a little more costly in construction actually as a regular ceramic vs. glass may be. However in the end I did find Isocleans very good with Tube gear, and Hifi tuning better with Solid state gear, but in most cases they both work just as well. There is one issue most don't realize, desired "Notable" effect is probably still very subtle however most prominent when replacing fuses in the Power amps, then the Preamp, then source gear will have the least effect as it just draws less energy.
The only way I have totally proven that they do in fact work by extending power and frequency response over standard and ceramic fuses is to actually replace every single fuse in my signal chain. Reason for most not getting full results is they start with one or two and hope for the best being they are rather costly. But when I pushed them into all gear including Power conditioners, Balanced transformers etc... feeding the system as well as the gear itself it made excellent results.
This will take some open minded approach and cost to do in most systems, and this will be effective. The problem with these fuses is the marketing alone, they do charge a bit much, and they have no trial period so you just lose money because nobody is taking them back, maybe even a re-stock fee?
If you skip some gear skip the front end gear for the most part in my opinion. Change the amps and any other power equipment for more results.
