Very interesting thread with lots of good information.
I believe allot of this product depends on our actual power source coming in along with our gear we are connecting, we all have different.
Reason I say this is I have owned several manufactures products over the years and found the end result differed when using with different gear.
Most recently I had 2 RM20's and they worked nicely with specific gear, someone whom I know who has the same Vac gear that I own currently recommended I give PS Audio's P10 a try so I purchased 2. I was pleasantly surprised and prefer them over my RM20's. My main interest being to protect my investment but not add any negatives. So far seems to be doing well, what was interesting while I still owned the RM20's was to put on a actual Fluke voltage gauge to see what the power was actually doing. I found this very interesting from one designated outlet and RM20 connected to the other one and actually deferring, what was there along with the fluctuations at different times, seconds.
For example the reading on one RM20 would be at 123v and the other say at 128v, they would always vary back and forth but never noticed both being ever very close, I did this for a week with head scratching results.
Hooking up the P10 there is a window that shows what's coming in and what's available "being converted", very interesting indeed. Using the P10 converts the power to 120v so both sides are consistent - I installed my Fluke again and confirmed this is what's happening.
To me that's important because now my gear is getting the same consistency.
Also interesting to see the THD IN and OUT - I see an average of THD 2.9% IN and then converted out to THD 0.1% OUT - this also fluctuates constantly.
You can go to their site for all the technical stuff but so far I'm very happy with the results but I'm always open to trying - learning.
The units appear to be well made and appearance wise look very nice, see attached picks - I have one placed under each of my mono blocks.
