Jafant, Audible Illusions Pre, and PrimaLuna Mono blocks amp; I made my own interconnect from wire that is no longer available. Speaker cable is Siltech for midrange speaker, silver and copper for tweeter, and a large wire of fine stranded copper for the woofer; each driver has it's own crossover, that allows me to run separate wire to each driver.
I just stumbled across a piece of wire for the woofer; "Stinger pro series pure oxygen free copper 12AWG"; it sounds impressive, (the name).
When you add it all up, the PrimaLuna amp provides a little warmth, but it's primarily neutral, allowing the music to come through without coloration.
