Wow, indeed. As with your analysis of a 2L recording in another thread, it suggests that at least some, if not many or even most, hi rez recordings possibly may not be as clean as they could be. Yes, we know there is always going to be a lot of ultrasonic noise in hi rez that is not masked by useful signal, but should noise levels always rise with frequency, as you have found? And, isolated steady tones just should not ever be there. True, some of these artifacts may not be audible, or at least minimally so, depending on the playback system. But, you never know.
I myself remain a believer in hi rez recordings. I still believe the added bit depth and improved filtering of higher sampling rates offer better sound.
I encourage you to continue this analysis to other labels. If artifacts are fairly common, perhaps we could find an effective way to communicate these results to the labels themselves. Labels might find these issues to be nuisance fly specs, but perhaps some might be interested in improving on these issues, whatever the causes in the equipment or in the recording/mastering studio environment. They may or may not be aware of the issues, but if the awareness becomes public knowledge, it might spur some reassessment on their part.
There are two hirez specialty classical labels widely held in very high esteem that I would be most interested in seeing results for - Channel Classics and BIS. Both are among the most popular labels in the hirez classical niche, praised for their engineering.
Channel Classics downloads and a recommended selection are at:
https://channelclassics.nativedsd.com/albums/38817-mahler-symphony-no-3-in-dminor
Not sure if there are freebies to test, but I would recommend the Mahler Symphony No. 3 on Channel as a highly regarded release from earlier this year. It is also a great performance. Note that the native recordings at this site are done in DSD, but this selection is also available in DXD = 352k stereo. Single movements can be purchased if you wish.
BIS downloads and a recent recording are at:
http://www.eclassical.com/labels/bis/stravinsky-pulcinella-suite-2.html
Recent BIS recordings like the above are done at 96k/24 bit. Older ones were done at 44k/24 bit. The native sampling rate is given for each recording.
