According to what I heard some months ago, Wessex, in addition to its current lower cost Dolce and Festivo euphoniums, might be displaying at ITEC the prototype of a new higher end hand-made model, probably called EP600...
I have no idea of its specs and playing characteristics yet, but it might be worth while play-testing this new Wessex, along with the Miraphone M5050, Besson, and various iterations of the Adams E3, E2, and E1.
