It sounds as if you are trying to correct a problem not in evidence. Are there any sonic aberrations you might ascribe to a vibrating fuse? If you hear nothing wrong, maybe there is nothing wrong.
Looking at pictures of the back of your amplifier, I do not see any provisions for a fuse holder, either integral with the IEC or as a stand-alone cylinder type holder. If there is nothing in your owner’s manual, you will need to pop the top to see if your amp even has fuses.
Some could argue that sand-filled ceramic fuses should better damp any vibrational energy that might affect the sound, and I have replaced most or all of my fuses with those, with the result that nothing much changed. You might get halfway there by simply wrapping some Teflon tape around the glass body of your fuse(s).....if your amp even has fuses.
If you want to get really adventurous, and mitigate all possible risks that vibration of your fuse(s) may be subliminally affecting your enjoyment of your system, then you could drill a small hole in a standard glass fuse and use a tiny hypodermic needle to inject your favorite non-conductive damping material (such as beeswax) into the body of your fuse(s). Or, you could pay
Audio Magic $225 for as many of theirs as you need.
BTW, the Hubbell HBL8300H Porter Port outlets recommended by
@jea48 do hold power cord plugs securely and sound pretty good. I still use two of them in my system. However, I cannot attest to the additional benefit added by the cryo treatment Albert laid on them.
