The answer is the second waveform is simply the original samples at 44kHz. The conclusion that the Benchmark DAC1 and others digitally clip is not proven by the two screenshots, it's shown elsewhere - the screenshots are just to illustrate the intersample overs you would be clipping with any DAC that does digitally clip. Some people say such inter-sample overs are few and hard to spot without heavy zooming, but this music shows the difference can be be seen easily throughout, at whole-track scale, with some recordings.
