Has anyone tried the Allo Nirvana SMPS PSU ?

The above has been out for a little while now and it seems to be a cheaper option to the Ashanti . I have an Ashanti in my main system but just interested how much is lost by using one of these items ? In another set up I could use an Ashanti to power an Allo Digione and a MiniDSP DDRC 22D or could just look at this instead . Any advice or views would be welcome .

I use one with my R-Pi/Allo Boss v2.1.
I was using an iFi iPower and this came along secondhand for a good price, so took a punt.
I would say it was a good step up from the iFi and also you have the option to earth the Pi. My headphone amp is double insulated with no earth connection, so being able to earth the system meant there was no longer the strange electrical sensation when touching the case.
