I live off the grid so my power comes from an inverter, it is called a pure sine wave inverter but it doesn't actually put out a pure sine wave. The wave is a series of steps rather than a  wave. The higher the quality inverter the smaller the steps are. I know that some electronics don't work well or at all on the ones with the larger steps ( mine is one with the smallest steps ). My power seems to be very clean and the voltage and Hz are very stable ( voltage ranges 118-115 and Hz 60.1-59.9, regardless of the draw).

Does anyone know how small the steps need to be for the equipment not to be effected and what type of conditioning might be beneficial in my situation?

Thanks in advance for any info, Mike

Mike,

As to how small the steps need to be to not effect your audio quality would depend on how good the power supplies are in your kit, how well do they filter out the high frequency components of the steps, and how well the non-ps circuitry deals with any remaining hf residuals that get through the power supplies.

That being said, a bunch (main cap and bypasses) of X2 caps across your hot and neutral lines would be the simplest way of removing the hf component from your ac.

Ideally, your stairstep inverter will contain its own filter: possibly a series inductor and shunt cap, or maybe just cap(s).

Can you get a look at your ac with an oscilloscope? This would allow you to see how much of the 'stairstep' remains.

FWIW

PS-PM me about getting some X2 caps if you're interested

You could use a regenerator, if your equipment is intolerant of a stair step form.
