Aside from shows, I have heard Kharma speakers in two home systems. In both instances I did not like the sound at all -- a strange combination of dry, antiseptic sound and dynamic lifelessness (i.e., poor microdynamics at lower listening levels). But, because I did not have anything to do with the setup, I cannot say it was the speakers.
I know someone who traded a Kharma (cannot recall which model) for the Anniversario and is very happy with the trade. Another friend has a pair which I have listened to quite extensively. It is a very musical sounding speaker. Another friend has the Stadivari, and it too, is very nice sounding. Given that the Kharma speakers I heard and the SF speakers sound so fundamentally different, I think you have to hear the Kharmas before making a purchasing decision.
