I understand that. Call me cautious regarding internet activity.
What I am mentioning is that I find it strange that this webinar is not mentioned anywhere else on the internet (that I can find) or on the Parasound website.
I have owned but no longer own an A21+. Maybe it is invitation only for current owners? And why would it be announced only 3 or 4 days in advance?
I am not trying to rain on you thread at all, just find this not usual.
