I think Mehran's 'truth about 4D' is less 'evidence' than 'his understanding.' I do not think it is proof. If, however, the mfr was willing to receive money to relabel one cart as another when they were not the same, that says a great deal about the company.
If anyone has listened to both, they could tell us. If they are the same, what has anyone gotten other than a moral victory? If they are different, how serious is that? I have yet to hear of anyone who has bought a 4D or an Atmos and been disappointed.
And in the end, it does not matter. The 4D still exists (for the moment). It is what it is and it costs what it costs. If anyone wanted an Atmos, you can probably still get one from Mehran. If you wanted a 4D, you might have been able to get one from Mehran before, but not anymore. However, you can get one in the US from the new distributor/dealer network. If they are different and the 4D is better, then so be it. If they are the same and more expensive - it is no different a situation than all the other carts in the line which will be more expensive.
