Eric says the Enzo XLs as well as the Pendragons and SEAS Pens (my first choice but Eric talked me out of it) are not nearly as good as the DIs and the Electrons. The info on the site for the Electrons is currently incorrect. Eric stopped making the Electrons with 6 inch woofers and now has them with 8 inch woofers. They are 2 inches taller and wider too. They now also come with a plinth to widen the stance as to help them not to tip over. I have the Electrons (speaker #35 and #36), yes he numbers and signs the back of his speakers. They are still HUGE speakers but the sound form them is heavenly at any level that is played.
