As it happens a few years back when I was doing a big speaker search I auditioned both the Focal Diablo Utopia speakers and the Raidho C 1.2
They were in the same store.
I wrote about my impressions of the Raidho here:
I give my impressions of a bunch of speakers. I listen to in the first post and Raidho C1.2 is listed there.
In the end, I found the Raidho a bit too coloured for my taste, a bit too laid-back in the lower treble/upper mids, and a little bit pushed in the upper bass.
As for the Focal Diablo stand mounts, that’s a way different sound from Raidho. If you’re looking for a more forward, exciting and transparent sound you’ll get it with the Diablo.
In the end, I found the Focal Diablo a bit too much in the “ultra vivid” category and lacking the warmth needed to balance that, which the larger Focal speakers can bring.
Not to pour cold water on your enthusiasm, but since I’ve heard both, I figured I would chime in.
I only listened to the Focal speakers once, so take that into consideration.
