@eualp I had the opportunity to buy the Corton EL34 monos from someone in my city. They are really nice to listen to with my AG Duo. I still have not had the opportunity to try the Cortese, but I am already very satisfied with the sound: very balanced, detailled, more precise midrange, sweet highs and very well defined bass but for better bass it was necessary to switch to silver interconnects between my preamp and the monos (mine are Van den Hull Orchid).The Shindo interconnects I listen in my system are also excellent and they are silver also. The preamp is an Allnic L3000 that I like a lot! One day I want to try with Shindo preamps to compare.
