I don't want to confuse matters any more but I've never been a fan of Simaudio. I've had an I3 an I5 and a W3 in my system/s over the years and always found the sound annoying. Almost like the amp tried to stand out over any other component, tirelessly trying to make every sound come through. I always wanted to like them because of build, style, power, etc.
These amps actually helped me understand that there are many sets of ears out there with all kinds of preferences. Never heard Tannoy but I think I would like it, Dynaudio never really did it for me either.
