Through my modified Signet floor standers, it is easily heard, the advantages of bi wiring and, passive bi amping. What a different set of characteristics, between running the system, horizontal vs. vertical. Using many different pairs of the same exact model amplifiers, I came down to really appreciating vertical. When going back to a single amp, things started to shrink, and collapse ( through the speakers, lol ). Over the many years of owning these, these Signets have bettered, ime, so many others. At this time, they are not in use...but they are one of my few audio products, I could never let go of. 🙂☹ My best ! MrD.
