Synergestic Black Fuse vs Audio Magic BeesWax

Ronrags... i have the same perspect as you, i feel that the SR Black was kind of bright ( overly aggressive ) when the music was at a complex stage especially at high volume it was more than enough.   It was a noticeable difference on each equipment from stock to AR Black, made every pieces of my equipment i put in different.    The SR Red i had at first was a great fuse but the black was a tad better, especially in the highs and bass area.  I had them both in my equipment and a&b comparison.  But if it was on the thicker side, meatier type, it would have been perfect!  

Perfectpathtech...can you please elaborate more of your finding on the AM beeswax fuses.  The specs sounds great ( beeswax is genius) but i want to know what characteristics does it bring before and after installing these fuses.    Much appreciated!  

Here is my dilemma:  I notice that with the SR Black & Red which i have on most of my equipment;  I have one in the amp, preamp and cd player.   Man... ever so often these fuses would blow out on me.   Should i up the rating say from a 4 amp to 5 amp?    Also, in regards to warranty, are the fuses cover under a  5 years warranty from Synergistic ( according to their website).   I went and did a search but it only mentioned other accessories but not fuses.  Any members who had the same experiences with warranty would want to help me out on this?    I did call them and they stated that it's only a 30 days warranty.   I am out of luck?   I am not too happy with their customer services!
