grannyring, that is very helpful, valuable information! I had not been getting much feedback on class D applications. This is very encouraging!
aolmrd1241, one of the reasons I have been posting "do at your own risk" is because guidance I received from industry members and design theorists varied, some saying there would be absolutely zero chance of a problem, and others concerned about possible oscillations with class D amps. I also had one maker of a NOS DAC who had concern regarding use of the Schroeder Method. His concern was the output from the DAC chip versus preamplifier. For these reasons I am taking a cautious approach rather than blithely telling everyone to try it.
Based on grannyring's comment It seems there are more people experimenting with Schroeder Method than are discussing here. It would be interesting to hear which class D amps are being used. Would anyone with class D and Schroeder Method care to discuss?
