Hi Fi Tuning Supreme fuse-Burn In?

Hello,
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.
Thanks!

You really can't get anything to do with facts straight, can you? The F5 has a massive 600VA power supply built to the specs Nelson Pass prescribes. Actually, it's the power supply for an F5 Turbo, but I wouldn't expect you to know what that means.  So if you're gonna call me some kind of idiot for building it to his specs, how about you email the man and tell him how stupid he is and how to build a power supply correctly. Please post the response you get back. I think we'd all like to see that.

geoffkait I’ve had about a dozen fuses...They go in and stay in until I melt them
Just because it was deleted doesn’t mean you never said it.

You’re obviously not at all familiar with the First Watt products. You know... Like the J2 that got Stereophile’s Amp of the Year award. Mine is a modified clone of the F5. The power supply in it is actually more muscular than what Nelson built the First Watt F5 with. The fuse pops at 300 watts like in all FW amps, but because mine runs 32V rails instead of 24V at the same 120,000uF reservoir capacitance, the in-rush current is a bit higher.
Like I said above, my amp uses very simple in-rush current limiting. In-rush current is the amount of power the amp draws when you turn it on. My amp uses nothing more than a pair of NTC CL60 thermistors to limit the in-rush

I’ve had plenty of fuses blow because my amp has a massive power supply and the most basic in-rush current limiting. I’ve gone through about half a dozen this year
.
How do like these apples, er, facts? You said it. You took a nice design and changed it to suit your fancy. Stop hiding behind Nelson Pass’s work. And while we're at it, why don't you email Nelson Pass and see how he feels about your mods to his design? I'm sure all here would love to know his views.

All the best,
Nonoise

For people who have massively built power supplies such as the Nelson Pass First Watt 7 Amplifier, it's sound significantly improved when I replaced the stock fuse with a Synergistic Research Blue fuse. 

I found this to also be true when I put a SR Blue fuse in the PassLab INT-60 amplifier.

I hate to be judgmental but, generally speaking, it appears a winning strategy might be to take whatever kosst_amojan says and do the opposite.
