The review should say at what level of loudness the auditioning has been done. Otherwise, it is not really possible to judge a review. I normally listen to music at a low volume. Above 80db there is a real danger of damaging the hearing capacity. Distortions > 100db are completely irrelevant to me. Same for sibilants at these levels of loudness. I guess that most of the reviews are based on listening at a relatively high volume.
