@kenjit - Now you are just arguing for the sake of argument.
I mentioned nothing about the speaker industry in general. I commented on Zu Audio's policy of offering a "free" in home trial. Of all people, I would have thought you would have embraced this policy. It is IMPOSSIBLE to be duped if you get to listen to the speaker in your own home and you have the ability to return said speakers in the event you do not like them or simply change your mind. This is called a CHOICE, Free Will, so to speak. This is a tremendous benefit for the consumer and a potential sales opportunity for the manufacturer. Win/Win.
One cannot be duped if they have the opportunity to audition the speaker in their own home. It's impossible to be duped. Everything is right there in front of you and you make a choice. Keep it or return it, based on your own criteria. Now, I'm not saying you can't make a mistake. But the mistake is on you as the listener, not on the extremely generous speaker manufacturer who has offered you the "free in home trial".
I think I may understand the problem now. You've made purchasing mistakes and now you are venting due to your frustration with yourself.
I sincerely hope you find Peace (and your perfect speaker) in the new year.
