Focal Sopra No 2 vs Magico A3

The reality is these are both terrific loudspeakers that appeal to two different listening priorities and profiles.

The Focal Sopras are a transparent slightly warm more emotional sounding loudspeaker with a warmer richer bass response. 

The Magicos are cleaner and less colored and may appeal to someone looking for more neutrality, they go a bit lower with a cleaner tighter lower bass, with a less warm midrange than the Sopras.

The Personas are in this same league with a diffrent profile then either of these loudspeakers, the Personas are a bit more focused in the way they image, have one of the least colored midrange and treble responses on the planet, and they also go nearly as low as the Magicos. 

So in summation three of the best loudspeakers on the market today each has their charms and fans, any of these speakers when setup correctly will sound terrific.

I like Focal industrial design, but it come with a heavy penalty of gross coloration from the lousy MDF cabinet. They should let Magico build their cabinets ;)

Coloration from cabinet is not always a bad thing. Someone may just as well prefer the colorated sound of the Sopras. Take percussions for example, that mdf coloration can give spooky real snare drum sound reproduction.

Spendor classic and Harbeth uses the thin wall cabinet resonance that gives that famous magic midrange to their speakers. Voices, brass and winds sound absolutely wanderful.

I don't see how people can enjoy speakers that they know perfectly well are "coloring" the sound, which by definition means they are not hearing what is on the recording.  Seems like it would be too much cognitive dissonance. 

Coloration is always a bad thing, unless you are building guitars.
There is no "magic" in MDF flexing.
