I remember watching a video about a loudness meter plugin that optimized a track for various platforms. They had a few examples of of minimizing the effects by keeping the LUFS at a certain point and limiting the peaks to minimize the effect of the streaming algorithms "correction". Not sure if that would help in the above example? I'll see if I can find that video and post it here.
EDIT: I couldn't find the video, but I did find this:
"Although there is no absolute loudness to which you should master your track, a great range when mastering for Soundcloud is -18 LUFS to -10 LUFS. Keep in mind that Soundcloud will normalize your track to -14 LUFS, so keeping the loudness around this figure will work well."
Also, on this page, they do offer a high quality streaming service, although I'm sure you'd have to pay something for it:
