Lets play with the idea, that Amir does a new test and the new amplifier turns out to live up to expectations, the specifications , maybe even better then so. What then? Do you dare to buy one? If one was wrong while another was great. If so, is it a lottery to buy one? You do not know what you are getting?Its still the test of one piece. To see if it a systematic flaw you need to analyze the problem. Or if you cant do this, you need more pieces. Or do a poll, how much other users have the same problem, at least. Before you come to the strange conclusion to hate all class d chipamps.
