I do not own the latest version (Sapphire, etc.) but with the M3TS, it seemed they were more forgiving, but I think you need to look at the whole picture which means source-amplification-cables-speakers. If a speaker is more revealing, that is a good thing, until (your) ears detect something off, which happens in every system depending on the recording. In my case, I enjoy what these speakers do well--huge soundstaging that sounds live, imaging that has the speakers disappear,great bass, etc. I have spent a lot of time on tweaking, which IMO is the icing on the cake, which has transformed the system from good to sounding great.
Perhaps the question should be, will getting these speakers force me to upgrade (amp, source, cables, tweaks). In my case they did and there are occasional crappy recordings, but the good one's sound great! Good luck!
