fuses - the $39 ones or the 85 cent ones

Yes is the answer to no protection. Yes is the answer to better sound. Yes is to the fact that I removed the ferrous cover to my ac mains. Yes is to the better sound resulting from the removal of said cover. Yes it is still covered, now with a non ferrous material. Yes I hope to replace the entire box with a non ferrous enclosure. Yes I believe my system will sound better as a result. Tom

I've had good results removing ferrous material near my equipment but it depends on the equipment and the situation.

What I'm saying, I don't doubt you got good results.

I hope you don't think I'm picking on you, I honestly do not know what the "non fuse magnets' are, or even how they work. Asking if they provide protection was because the description is "non fuse."

If it works for you and you're happy, it does not matter what anyone else thinks. Most of my equipment needs fuses because I run all tube. If a tube shorts out and there is no fuse, then something gets burned.

Albert, I don't think your picking on me. I am just reporting to those out there my experiments, trials and results. I don't expect others to try what I have. Reading someone else's idea, experience or result may trigger an expansion of that idea or add a new direction and possible benefit. One expansion of discourse posted here is the possibility of controlled resonance of a vacuum tube filament within the confines of the glass. Tom

I've always wondered why the hi-end manufactures do not put these in right off the bat. Makes sense to me. Its one thing to let people buy the cabling they want but finish the job on the inside of the gear. Add the better fuses!

Dvrs -- some manufacturers are doing that -- such as Dan Wright of Modwright who posted some comments here.
