Sidssp, on a serious note, I wonder if there are benefits. When you think what we spend on power conditioners to filter out the bad stuff imposed on the lines to our homes. You would have a pure sine wave without any "noise" imposed as long as you can disconnect from the inbound power company supply line. If you use a power conditioner, I would try bypassing it for a time and at night when you are back online, listen if you can hear a degradation.
I would be curious to hear your results.
