Power regenerator vs conditioner

I use PS Audio older Power Plant Premier. I have Purist power cord from the wall to it and better Purist from the regenerator to power amp. Still, sound quality varies dramatically depending on how bad the incoming current is. If I plug the amp directly into the wall, the system is unlistenable most of the time, the wall current is that bad. So yes, regenerator helps a lot but it's not really good enough. Maybe newer PS Audio regenerators are much better, I don't know. Anyone compared ?
My SS amp is 80 watt/ch. Tape deck cares less about the current than any other piece of equipment in my set up, turntable and power amp care most.

Ralph, I see, thank you. PS Audio has a good trade-in approach. I can get $1.5K for my Premier if I buy $5k regenerator, so it would be $3.5k for me.

For $18k custom batteries that would power the entire system would be preferable. Anyone takes this kind of order ? But there are no perfect solutions, batteries would give some noise too and dynamics might be compromised a little. I mean great custom battery with the right response and discharge curve.

Now those German things look serious and they use safe chemistry for batteries. $30K ? That's almost nothing, some of us buy cartridges for $15k, cables for $25K and records for $600 or more.
Additional way to manage the current is to buy equipment with real power supplies, not some toy parts. Plus good power cords.

I want Stromtank and I want it now. I mean right now !
