AC Regenerator

has anyone ran a comparison of the signal on a real digital scope vs what the unit is telling you?? The units that i had seen calculated THD and the sinewave for the readout with software but did not actually measure said aspects live online.I know this because i have scopes and THD analyzers on line at all times. ps Just bought another THD unit today. the frequency chop in the AC oscillator part has shown noisier than that output of a good UPS and a IGBT AC drive. too many high order harmonics. 
again I say run your stuff on DC battery power and compare.
just about every componet converts the AC plug into dc later anyway,
this is the next phase of top line audio equipt.
Hint-the military does this for many critical instruments and not for fear of loosing power. For finite noiseless signals and NO ground loops ever.

@hifiman5 —Oh, OK; thanks. Actually, I was wondering what anybody who owned a harmonic distortion analyzer would be doing on a forum site such as this one—but that's a whole 'nother can of beans. Amen.

All AC regenerators have an amp inside that needs time to warm up before sounding great.

I hate warm up sonic changes, and use Chang LightSpeed line filters, and never went back to a AC regenerator.

The Chang sounds great with no coil voltage lag, or current limiting, common to other conditioners.

I did try the P10 with a 30 day return option, and it stayed in my system.  I will likely also demo the P20, given the word of mouth from others that have upgraded on this path.  I can hear for myself and decide if it improves things and if it is worth the scratch.

PS Audio is actually quite good about promoting home trials to make sure you like what you are buying.

By using 50% or over will increase all harmonics and output stability,
see design specs used for all critical power systems. it can be shown in the math-do it and see, thats why Mil spec calls for 3 times rated load capacity. use that for your feed and enjoy improved power signal

Also please use Power Factor correction Caps on your Listening area power ,cause all the X formers cause a bad phase shift in input voltage otherwise. a few 100 mfd caps across 120v line for every 1000watts is good. or go to 3 phase as Vrms beats the .707 instantenuous value

my point is that there are tried and true standard ways of fixing up all your power problems and therefore your resultant sound without giving into the marketing hype of regerative sales at like 1/4 the cost.
IE- pro studio recording desgns.
Heck just going to balanced/isolated ground inputs can bring noise floor up 10 fold at little cost. to you.
