Hi Fi Tuning Supreme fuse-Burn In?

I've gone through the Hi Fi Tuning line of fuses starting with their Silver and then on to the Classic Gold.
I recently purchased the the Supreme.
The Supreme does everything I hoped it would but as with anything in this crazy hobby, there's seems to be a trade-off.
I'm getting more clarity and air but the presentation seems to have an edge or sharpness to it.
If everything was just slightly more-should I say organic?-I'd be one happy man.
I have about 60 hours on them.
Will more time smooth things out?
The Gold's are definitely smoother but they lack the air and clarity the Supreme's provide.
Any input would be greatly appreciated.

I gave up contributing to the thread of the superhuman hearing creatures
And yet, you still persist. Which is it?

Huh? I don’t know what your game is, pal, but obviously HiFi Tuning is a big proponent of fuse directionality. Why do you think HiFi Tuning puts a diode symbol on their fuses? You are either mistaken or don’t know what directionality means.
