Exactly, Romy. Also, it is not so easy to come up with an alternative where the charger keeps up with the battery drain! But because I have a short memory I have been wondering again about taking one's time to charge the battery (or, batteries).
One thing most of us will run into if attempting "home brewed" AC regeneration is that the "commercially available" DC/AC converters are also too noisy for hi-fi. But I have never heard anyone complain about the PP running off its batteries, which, apparently, means they have at least put this one behind them... Sure it is not a "good value" to buy bigger batteries and own chargers to do this job with just the PP down-converter, but I think this is basically a matter of voltage...

This same site lists a very high quality giant (88 pound) battery, as an example.
I am pretty sure you'd have to unplug the charger to listen to hi-fi...
and the usual problems arise if long play time at high drain is desired...
Just mental fishing, and I understand that APS says, "no difference", but I keep thinking the PP grounding arrangement (and so, the "circuit"...) has got to change when the up (AC/DC/charger) unit is engaged versus when it is running battery/down only. Among other possibilities this may engender, I wonder about the possibility of "noise re-cycling" or "inappropriate" shunting on the neutral/ground matrix...
Romy, did you mention whether you have measured [across] the neutral and ground legs of these new units yet?
