Charles,
I agree. Best to try and see if it works for you.
As I said, it works for me.
It's only a small outlay and if it doesn't "float your boat" then no real harm done and like all of us you can sell it on for nominal loss.
Re the Beeswax, I use it on a Audio Research Ref75SE and one on a vintage Meridian CD player.
Both sound better over the standard fuse.
Changing fuses maybe more noticeable/beneficial the better the gear is.
We all have different perceptions regarding what we like and don't like, what we hear and don't hear, ie. different cables, amps etc.
Experiment.
Isn't the differences we perceive half the fun of being interested in our hobby.
