I was very skeptical of these but found out 2 other Audiophile friends a state
over from me had the older crossover enhancers ,now have the Graphene based Carbon shell models like their Graphene Blue Fuses these filter the high-frequency hash and the Electromechanical fields within the Xover.
they liked the Carbons noticeably more . They said 75 hours to get about 90% runin then 200 to fully refine . I bought them myself and Dam within 12hours
i can geara clearer Audio presentation . I have not been a big fan of a lot of
the Hype Synergistic has done in The past like the active shield I had them sold them , but theirBlue Fuses are very good ,
and I want to see just how much better my speakers get and in which areas after
I log 200 hours . I will just let play for a solid week ,and then deliver my exact findings with several other ears to judge them.
