LEHRREICHE HÖRSESSION | Gibt es noch einen Grund auf Class D zu verzichten? | #wiim #rotel

Until now, I've always been able to easily distinguish a Class-D amplifier from a Class-AB one. However, things have changed, and there are now Class-D devices that are virtually indistinguishable from conventional circuits in terms of sound. Many thanks to Audiotrade [ATR] for providing the equipment. You can find the Wiim products here: https://wiim-audio.de/?gad_source=1&g... And if you'd like to take a closer look at the Rotel amplifier, you can find it here: https://www.audiotra.de/rotel I test these products without receiving any payment.

I request these from the manufacturer/distributor and usually receive them as free samples. Therefore, nothing is shown "at the request of a manufacturer," but only things that are of interest to me or you. And there is no monetary compensation for this ("money for testing"). The exception is paid advertising, which is then clearly and explicitly declared as such in the video. This serves to finance the channel in general. This is a presentation of my development work and technical information without warranty or guarantee. This is just one example of how it could be built. Any construction or reproduction is done at your own risk. This applies to compliance with technical specifications, operational safety, as well as the success and sound of any reproduction. Any liability for damages is excluded.
