I don't have a scope, so can't measure the output of my particular unit.
I do not think that scope is necessary. Pay attention that my Units #1 and #3 have very fine scope outputs that is not related to their sound. A scope is something that just allow to see obvious problems but does not say anything about Sound.

However, if I were to guess, I would say that my unit probably falls alongside your #2 unit. When run from AC, the bass disappears and the sound becomes bright and edgy, to the point of being unlistenable. From battery though, the sound is full and harmonically rich - very, very nice indeed. Quite frankly, you would have to be deaf not to be able to hear the difference.
This is the problems. I do not know where it falls alongside. Your unit might falls alongside with # 5 or #222, or to have own set of sonic problems and we do not know what is responsible for those problems. Do not forgets also that your unit is 220V and your DC-DC converts need to punch voltage higher then 160V as US domestic units most likely do. If anything then from your description of sound most likely falls alongside with my unit #3 – “bass disappears and the sound becomes bright and edgy”. You find it unlistenable but I in my comment above called it as “semi-usable as a temporary solution”. I need to explain why: I run 7-channel system with ability to set volume of each channel separately. So, last night I celebrated Macondo to run from new PP2000 – I shifted the entire balance down, compensating the upper range nose that PP2000 look like produces. This made my sound listenable, now where I would like it to be but listenable as a temporary solution.  BTW, the way how you describe the sound of your unit running from butteries it was how my old PP2000 sounded from AC lines. Yes, there was some difference between my old unit ran from AC and from buttery but it was near even close to what it today and it was very-very-very minor. I did bring in my old house people and demonstrated to them that the difference between running from AC and from buttery is insignificant. Ironically, my first PP1050 from 2007 had no difference between running from AC and buttery all.

Having said that, when I first received my unit, I had it connected to the system in my study. During an email exchange, I agreed with Bob Rappaport that there seemed to be no difference in sound between AC and battery…
What do you do taking with Bob Rappaport about sound. Bob Rappaport is a pimp who moves boxes and counts money. To talk with him about sound is like talking about love with a very cheap prostitute who sucks for $5 in railroad toilets. Bob Rappaport is a sales clerk. An Hi-Fi sales person is in a scale of human values is something in the middle between what you blow out of your nose during a cold season and what you flow out of your ass after you eat non-fresh food…

I'm not sure, but perhaps if more PP2000 owners voice their opinions, PP will stop living in denial.
I do not think that it is necessary. I do not need to collect opinions I know the truth. PurePower do not need to collect opinions, including from me. The need to produce a product that has default operational sound and the made of the product shall be assurance of default, repeatable and predictable result. Otherwise it is a pure BS.
