Thanks for advice! I dislike it, however, when an honest question is turned into a stupid statement. Rpeluso writes as if I've left my ears behind - I have not. Going the visual way is a "nightmare". Well perhaps not though I trust my ears mainly. And Sunnyboy1956, where has Lyra said that SRA/VTA plays no role? It is more that they try to adjust for some margin, in my interpretation - but J Carr would be welcome to speak for himself. "Not a great fan" - who is? Karl Marx talked about the world of neccessity. Few audiophiles "want" to go into this SRA microscope testing business. The reason they do it, is to get the best possible sound from their pickups. Same with me.
