- On one hand, during the fantastic TotalDAC discussion on ASR this summer ( the whole thing was so incredible that I read the 100 pages twice!, and that really motivated me to join ASR
), such ultrasonic components were found out, a few subjectivists said that it didn't matter as they cannot be heard, yet what I perceived as the "dominant", "enlightened" view an ASR was that it was really bad
because it could quite negatively affect the electronics of further devices (e.g. an amp for speakers) downstream or the behavior of transducers ( tweeter, headphones).
- On the other hand, when it is created by MQA it is OK because it cannot be heard
