I actually have one very similar to the top of range DC3 and I don't need it. Very well built and substantial.
If you'd be interested please drop me a PM.

I would suggest you use a battery with the Caiman, it would work out cheaper and would likely be better. I have been impressed with the one I use and John and Martin use an alternative for theirs which they rate highly too and is even cheaper than the one I use. |

also looking at these,i used batteries years ago on some naim gear,i found them quiet smooth pretty good but seamed to lack deep bass notes and dynamics you get with a large linear supply,it may have been my system www.teddypardo.com/dacs.html |

Battery power for a Caiman for sure.
Big sound upgrade

As John said. The Caiman works very well on 12V battery.
The reason we're recommending 12V lead-acid is it's their native voltage (more like 13V in practice) and has very low output impedance. Mobile batteries offering 12V have an internal DC-DC converter stepping up the voltage from internal 3.3V Li-Po type batteries so are not as clean in their output.

The 12v battery has out performed an Anker and a Hypex 100 linear power supply with the Caiman

In my case, the 12V lead-acid has beaten XTPower and Ankaka batteries and a Paul Hynes linear power supply.

Not sure what you mean by 'mobile battery' most Li-Ions just stack the cells to get the required voltage, there's no need for a bucking convertor like you may find in LED torches. 3 Li-ion is 12.6v fully charged, (11.1v nominal) Batteries are actually quite noisy and it's trivial to make a PSU with both less noise and a lower output impedance than a battery.   6x LT3045, up to 3amp out any volt in from 0-20v, out from 1v to 15v, way less noise than the chemical soup inside a battery. |

Not sure what you mean by 'mobile battery' Many of the small high capacity batteries that create 12V (usually switchable) use internal 3.3V or 3.7V Li-Po batteries, stacked for 6.6V or 7.4V. They use an internal buck converter to derive 12V. They still sound better than an SMPS but a lead-acid walks all over them for sound quality (certainly in my setup driving a Caiman SEG directly and a Pi 3 on 5V via a step-down buck converter). |

Shock horror I agree with Simon on this one  Has Hell frozen over? |
