Nagra Classic DAC 3rd Party Power supply

So I'm auditioning the Nagra Classic DAC and enjoying it very much . Nagra offers the Classic PSU which is supposed to make a substantial difference in sound quality

Will their older MPS work with the new “classics”?

It is 12V, so I would think any 12V power, entering with no ripple, coming through a Lemo connector, should be just dandy.

There is also the battery option for the older MPS.

I guess the power condition must be ~20k for the new one?

luckily they do not need a power conditioner and a fancy power cord… I hope.

I used to own a Sim Moon 650d DAC ~$8K… they offered a separate power supply for $8K. With some reticent I bought it. It was well worth it. The noise floor dropped dramatically, which allowed the details to increase and bass was enhanced. 
 

Personally, I would go with the one manufactured for your unit. It was made to be a complement, you can be sure if they are selling it at that price, it is made to be perfect.
