[ultrasonic]

Nobody seems to be able to do it. Instead, all we get are these abstract tests like Kunchur's, involving some most definately non-musical waveforms with questionable relevance and inconclusive results.

I agree. Not a single positive result in a decade is simple but mortgageable evidence.

Does this count?:

Perhaps you might detail the testing setup and apparatus, and the length of the test for us?

This link appears to be broken.

The correct link appears to be:

This appears to be a year 2000 summary of the well-known Boyk paper that only documents the allready well-known existence of ultrasonic harmonics from musical instruments.

"This completely different paradigm for digital audio recording (SACD) does away with the anti-alias filters needed for PCM (CD and DVD-A) analogue waveform reconstruction. Preliminary reports in the audiophile community indicate that SACD has a natural quality of sound that DVD-A has yet to demonstrate. Ironically, one of the descriptions of SACD, this radically new digital format, is that it sounds "like analogue", meaning like LPs, ancient technology. (LPs i.e. vinyl records are associated with having smooth, relaxing presentations, that while sometimes not as impressive per audiophile standards, nevertheless can offer perfectly enjoyable music. The same is not always true, and in fact is seldom true, for CDs.)"

This is not evidence, it is supposition. Furthermore, the article contains errors of fact, some that were known to be errors when it was written, others that have come to light since it was written.

This is the oft-debunked Oohashi paper.
