Synergistic orange fuses

Hi there,
I’ve been a (background) member of Audiogon for a while, so firstly I’d like to thank many of you for the expert info that has lead me to my current setup, as I live in London - an to be totally honest you ‘Americans’ seem to be WAY ahead when it comes to audio + tweaks, etc...
Before inserting the 2x new fuses i thought I was producing some pretty nice sound, etc... music (certain recordings) appeared to be played live in my living room.
however, I just received 2x orange fuses which I have put into my Ming da monoblocks (feeding each pipedream 21 tower) and somehow... I feel underwhelmed??
At this moment in time I actually prefer the cheap glass fuses that came with the amps as they seem to give a lifelike presentation, as opposed to the synergistic research - Which seem to muddle things with, dare I say, too much body’, and not enough sparkle up top.
i know burning in helps, which it ‘has’ definitely over a few hours playing, but how long should I give them before (perhaps returning them under their generous 30 rule?)
Any help would be greatly appreciated!
