Maybe Alexey can du some funny things with his boxes ?

 

But reading John’s post, doesn’t give me much hope.

Can someone invent a way to parallel two UltraCaps ?

 

It must be possible adding some circuits after them...

 

 

Why not?

It is easy to improve LPS1.2 specs with my boards

take few LT3045A (1A) boards
wire outputs for parallel as described here

feed individually (inputs not paralleled)

LPS1.2(1)-LT3045A(1)\____ load

LPS1.2(2)-LT3045A(2)/
 

P.S. Not tested but should work, will do some test and update
P.P.S may be @JohnSwenson or @Superdad can comment on this trivial solution?

Just finished small test

Yes - it it easy to parallel ANY power supplies with LT3045 regulator boards, need to wire LT3045 outputs for Parallel, connect SET networks and can feed with different PSU. 
Below 2 x LT3045 5VDC out board with outputs connected in parallel, as you can see the current for each PSU is NOT matched (1st pic), but as soon as you connect SET networks (SET PIN) it is balanced perfectly (2nd pic). Moreover 1st board feeds with 12VDC, 2nd with 15vdc!!!

How much is the voltage drop over your boards ?

 

7/10V

Unless I missed it, neither do they give any graphs for output impedance with frequency.

Hi

 

Not sure that manufacturers should claim that this regulator "good for audio", but you can find some expensive "audio grade capacitors"

 

For the output impedance - check link below
https://www.belleson.com/comparenewzout.php

 

And finally -  performance of the regulator depends on the components around it., but i don't think you can find best possible option.

One of us must misunderstand each other 😀

 

If I parallel two LPS-1, at the maximum 7V. What is the best I can expect on the other side ?

 

Or did you mean 0,7 V ?

ok
Best if you can use 2 x LT3045A (1A) boards configured for 6VDC out 
LPS1 7V  -----    LT3045a 6V\_____________6V 2A
LPS1 7V  -----    LT3045a 6V/
