Brand: CADENCE CADENCE was founded after years of research into electrostatic transducers and hybrid speaker designs. In the early 90's, a revolutionary breakthrough was made: the hybrid electrostatic AMAYA (ES MK II) loudspeaker made its spectacular appearance. Following soon after this came the pentode- based hybrid valve amplifier, the VA-1.Today, besides the AMAYA (ES MK II) and the VA-1, CADENCE has a flagship reference hybrid loudspeaker, the ARCA as well as an entry-level dynamic speaker, the DS.
