I use Monitor Audio PL-200. Which use also full silver internal. Monitor Audio Always want to use better materials in there speakers than other brands use. Why you think Avalon closses there speakers? I met a person who owned the Diamonds. He opened the speakers ( which was not easy to do) and he was amazed about the simple filters and cheap internal wire they use. Simple copper. The Pl-200 also uses the best WBT terminals. ( platinum version) Copper often works better wenn there is copperwire internal. But.......the difference between silver and copper is stunning. Wenn copper works better you probably have copper internal. Believe me you loose speed, resolution and focus. Realism in sound is often better with silver. Because Avalon uses simple copper inside ( more cheap for them) you cannot use silver. So thanks to Avalon you get a lower end result. At the show in April were I was with my set, other sets had less resolution. I was amazed about how less information there was. This were very expensive sets like the Magico S1 with Zanden and Kubala Sosna Elation cabels. For example Bruce Springsteen ; Brothers under the Bridge. The ss and ttt and th of his words were almost not there. My image was even superior in depth, speed and in 3d touchable image of instruments and voices.
