Hello My brother has the Einstein and myself have tried all others without question the best fuse out there period, if the new Synergistic research Black fuse it use the space age Graphite, which BTW Nasa uses,as well as all new Super computers
Exceptional detail and a more organic sonic presentation they are $120-130 each
But if you buy Sevrral email tech at parts connecxion ask for Chris they may be able to give you a Good deal. They do take 200 hours to fully runjn but even after 50 no question ,the fuses are directional go with writting direction of the signal.
They come with a 30 day money back guarantee . We are not sending them back
I did my whole system started with digital once I heard them the whole system
Even the Subwoofer is Clearly more articulate and defined.I took the Black fuse out and put the Hifi tunjng Supreme fuse back in for a hour just to see .
The SR Black fuse without question The Best Tweak out there Period and a bargain for under $600 my system never sounded this good.
