Masterbuilt Signature power cords
I had previously installed the Masterbuilt speaker cords and interconnects to good effect. I then tried installing the MB powercords on my Spectron monoblocks in place of Shunyata Python CX powercords. As soon a I powered up the first Spectron, it was obvious that the quality of realism had taken a huge leap. Since then, I acquired Double Kronzilla's, using them in a biamp configuration, all with the MB cables. The Krons, like the Spectrons, love the Masterbuilt power cords.
Without exception, every time I demo the difference for audiophiles or casual listeners, there's the same reaction. Oddly enough the first words are usually "holy crap" or equivalent.
By the way, I got the same result replacing Anacondas elsewhere in my system.
My word of advice is once you've tried the Masterbuilt cables, you'll miss them if you don't keep them.
