It certainly seems that once sinusoidal shape gets within a certain spec range its differential effect becomes negligible. This doesn't necessarily mean that more drastic deviation of sinusoidal shape would be inaudible.The only other factors I can think of are AC current moment to moment availability, grounding issues, RFI, EMI and magnetization of electrical components. These other factors are why passive line conditioners can also exert a positive effect in some ways. Are there any other power related factors??

Pure battery operation of audio devices seems much more positive in its sonic effects with the main problem the lack of power to produce fast transients and dynamic changes. Small batteries seem to be too weak but isolation does seem to a decisive factor. Of course the regenerators combine the battery operation with AC replenishment. Once you introduce external AC current into a device however its effects are unpredictable. I suppose the use of class A/B or D amplification could be involved but why that would make a difference with a simple AC wave is not clear unless the class D switching is somehow important. I do agree that extended UPS beyond the few minutes needed to shut down the audio system is not essential and would simplify things.
