I do. I bought all of my speakers without seeing or hearing them. Coincident Technology Pure Reference Extreme, Wilson Audio Sophia v3, Magico S3, Magico Q3, Magico M3, Magico S-Sub, Magico ACC. Gotta be $200K+ worth of new speakers there bought sight unseen sound unheard.
I'm not a fan of the FR30 aesthetic, it's ugly. For $28K it's at the same price point as Magico A5. I mean seriously, who would buy FR30 when you can get A5 for the same money? At least the PS Audio gives you an alternate color option. They have been developing this speaker for 5+ years so it's about time, they would have spent a lot of money getting it to this point.
