Utopia Skala / Alto speakers anyone hear them both

It's Scala Utopia fyi. I'm interested as well although I'll be listening for myself at some point.

I'm just trying to see what I want to do to the system I am building

I can already see what: you're going to throw money at it:)
Back to the question. Scala vs Mezzo Utopia, correct? If so, Scala without doubt. The sonic homogeneity is far superior, especially in the mid-bass, lower mids region. The Scala's tweet is also good (for what it is).
No idea what your electronics will sound like, though.

Scala vs. Alto is the question.

Greg,

I don't understand your comment about the Scala's tweeter. I know that the Utopia III line has a different tweeter from the previous Utopia Be it replaces (e.g., 27 mm dome tweeter now vs. 25 mm). BTW, I am considering the new Diablo Utopia 2-way.

Scala is much better.its deisgned by another enginier in Jm Lab the tweeter itself is 3x better than old ones. tweeter better, implementation in xover much better. midrange basicaly the same.
