I have been enamored with the Joseph speakers, started off wanting the Pulsars, moved to wanting the Perspectives.
I auditioned tons of speakers including the Raidho X1s and C 1.2, which were being offered in a very good deal from my local dealer.
I’d been quite impressed by Raidho monitors briefly hearing them at shows. But on a longer listen I decided they weren’t for me. In a nutshell, though the Raidho tweeter does indeed make for very fine high frequencies, the actual tone and voicing of the speakers were a bit too obviously scuplted to my ear. I found the Joseph speakers to be more tonally beautiful and convincing and also more neutral-sounding (in a good way) than the Raidho. Also the Joseph speakers have stellar high frequencies as well in terms of natural, ease, and sounding "unmechanical."
I can certainly understand why someone would choose a Raidho instead, as of course it will come down to personal taste.
You can find some more detail on my Rhaidho audition in this thread:
