I might know that there is an issue with KH120IIdsp speakers - they have trouble waking on a signal from standby mode and die completely after several weeks\months if the standby problem keeps occurring. I know 3 persons that have that issue and at least 3 more people reported the issue on this forum.
I think I found out what is the problem and I need someone to verify it, as I can't fully verify it as I sent my speakers back to the manufacture for repair.
So as far as I know the issue appears only when using SPDIF workflow. You may use SPDIF for KH750 and XLR for KH120II and your sub only will hang. Or you may use SPDIF to kh120II and your speakers will hang or both sub and speakers will hang if everything works over SPDIF.
I use AIMP to listen to the music and the player is capable of changing audio-interface sampling rates to match the song sampling rate so no re-sampling occurs in the audio-interface and a bit-perfect signal comes to the speakers(sub). It won't work perfectly with all audio-interfaces as cheaper ones need some time to change their sampling rate and may hang if you change songs with different sampling rates too fast, but you can do it manually in Windows settings. So the point is to send a signal of varying sample rates to the speaker's DSP. After that let the speakers go to sleep\standby and try waking them up with a signal.
I managed to hang my sub this way on purpose, but the sub has a bit different firmware and dsp module, so a test with KH120II are needed to confirm that. It may save many speakers and troubles for people.
