Also this DIY LifeP04 supply is making some waves on diyaudio:

I have previously said the same in A.S. as Iancanada says here.

 do not suggest using and LDO or regulator after LifePO4 or ultra capacitor power supplies, that could degrade the power supply quality.

I think the ciunas is only at 2 A but then it states > 2 Amp so does it mean it can do 3 A or more if needed but all the time ? 

 

 You would need to ask John Kenny that question.

It's a linear regulator made with discrete components.

 

Going by the residual mains related artifacts he may be using a bridge rectifier without a bulky transformer, a bit like the original transformerless TVs with hot chassis from years ago,(Rank Arena, Sharp etc.)  then regulating the voltage output with his discrete Linear Regulator ?

So why not use two sMPS in series at half the required voltage in a balanced configuration and add a common mode choke in the right way?

Hi Gary

 It may not be quite as straightforward as hoped for ?
