Kef Blade or Wilson Audio Alexia?

Heard both and RMAF. I found the blade unobjectionable (perhaps not the right aspiration for a 30k speaker), and the Akexia's to be "Wilson-y" (just the thing, for some people).

Lots of choices, at your price point (or any price point!): at this year's RMAF, commercial products with comparably fancy builds from Venture, Vivid, and Sony were competitive with those you mention (to name only a few).

In terms of design, technology and research and development KEF can outspend Wilson, Magico, YG acoustics and ten other speaker companies combined. The Blade program was over 1 million dollars spent in R&D over five years

so as I said you have a magnificent but very tricky speaker with the Blades

How much to get a 30k speaker that's *not* very tricky? ;)
