Out of all of the KT88s I have tried, The Sophia Electric Blue Coke Bottles beats everything handily. I have not tried the WEKT88 Plus but I did buy some WE6SN7 Plus and after 70 hours of use, they spank the CV181; more transparent, deeper/wider sound stage, much lower floor noise and very good sound quality which was a pleasant surprise...
