SIMAO,
I'm not sure you would be happy with Cornwalls given your speaker history. Can I suggest something else? Perhaps a triangle Quartet or Antal. Very tube friendly and they would give your system a good amount of bounce and liveliness. I run Antals (gloss black) and with added subs they play well above their size. I think the Triangles are a huge step above the Klipsch. (I own HeresyIIIs and have demoed the LaScala for a whole afternoon).
