Best (sane) choice to power micro/ultraRendu?

Informational.

I knew that the Teddy Reg started out as a DIY project in  Pink Fish Media.

A DIY oriented member could build this earlier version, as it is fully documented.

 

I don't think Teddy intended it as a DIY project. He used the community at Pink Fish (which he participated in anyway) to help him refine the design. He then released the final design to the DIY world, with the request that it not be used commercially to compete with his own commercial products that use the design (he didn't patent it for that reason).

 Are you SURE that the Pardo is a Linear PSU, and using a transformer ?

 

 

Look at Teddy's site, where he favorably compares his tech to linear supplies; it isn't a linear supply, just a low noise one.

Most regulated power supplies today are either Switch Mode Power Supplies (SMPS), or linear power supplies. Our power supplies are based on the SuperTeddyReg, a different technology which has proved to be far superior for audio designs.

the quoted page makes it pretty clear it isn't an SMPS or a linear.

It also has a graph with measurements, for what they are worth. On his individual product pages the explains the graph like this:

...the graph shows the noise level measurements of the original wall wart power supply (red line), an alternative power supply based on a Liner Regulator (blue line), and the Teddy9/2 power supply (black line). The brown line is a zero Volt reference which is actually the measurement equipment internal noise. As can be seen the Teddy XXX power supply noise level is very close to the zero Volt reference.
