This is the clip that AP uploaded in May 2020 AKP Single 1024 pixel prototype chip on Vimeo (this is the sample before the 'clean room loud fans' clip).

I have high end B&W speakers. When I listen to this clip I clearly hear hiss. This hiss is not there because my speakers are not of sufficient quality. A well recorded sample played back on high quality analog speakers will demonstrate that this product actually works without obvious degradation or artifacts caused by the AP chip.
