BRZHiFi X20 (2xTPA3255) VS noname TPA3255 amplification levels

I am sorry for the amateur makeup of this video. I just wanted to show the amplification levels, measured on a 1KHz tone with the same input volume, to the BRZHiFi X20 with 2x 600W and 2x TPA3255 AMP chips (marketing), and the difference to a noname 1x TPA3255 AMP. Measuring with a mobile phone is never exact, keep that in mind. But with the same input levels to both AMPs, just changing the speakers from one to the other AMP and then comparing the output levels should be comparable. The first volume level is 100% on both AMPs. The second is 50%, where the BRZHiFi X20 could hardly produce any hearable output of the 1KHz Signal. The noname TPA3255 AMP could be lowered to 1/3 of its amplification volume to produce nearly the same volume of the BRZHiFi X20 100% amplification volume. Sorry for the moment when you hear no output of the 1KHz signal, I managed to juggle out the USB DAC when I changed from one AMP to the other. The volume levels on the PC stayed the same, I checked that (when you hear the mouse clicks). Marketing VS reality. Or as we would call it in Germany: § 123 Bürgerliches Gesetzbuch (BGB): Anfechtbarkeit wegen Täuschung oder Drohung - Die vorsätzliche Täuschung durch falsche Angaben kann zur Anfechtbarkeit eines Vertrages führen. § 263 Strafgesetzbuch (StGB): Betrug - Das Vorspiegeln falscher oder das Verschweigen wahrer Tatsachen, um einen Vermögensschaden zu verursachen und sich oder einem Dritten rechtswidrig einen Vermögensvorteil zu verschaffen, gilt als Betrug.
