I have directly compared a pair of the Kimber PBJ's and Hero's. The cables are quite different. The PBJ's to my ears were more transparent and had a deeper soundstage. The Hero's were a "better" cable in the sense of detail/low end and had a wider soundstage. I heard more expressive base that sometimes overwhelmed the mids/treble and ended up muddying the waters in my system (kef LS50, red dragon s500, metrum amethyst DAC). That being said, I liked both cables differently but did not want to choose between the better aspects of both cables for an upgrade.
Because of that, I went with morrow's MA-4 interconnect which you can get used or at a serious discount. Never pay retail as Mike often runs sales. I previously had an MA-4 running between my passive volume control and power amp, but wanted to try one between my source and the passive pre. I bought a used cable and to my ears, has the best qualities of both Kimber cables if not surpassing them in more detail and a more balanced sound. I splurged for the silver interconnects and I found that they give my system a faster feel and more sparkly on the top end.
However, I am also interested in Mike's new cable design. I wonder if there have been any tariff impacts on silver prices in his supply chain. I am contemplating purchasing new SP-6's to compare to my old SP-4's and will likely start a thread if I do to help others out.
