Gustardx26 pro vs RME ADI2FS

No doubt the RME choice of power supply is not critical due to its triple stage regulators. But some wallwart smps inject noise back to the ac mains, unless all components in the audio chain can handle/reject those noise, otherwise SQ will be affected.

Thanks for everyone's input. 

Was also wondering with all the functions the RME has, many of which I am getting lost in with the tree they use. Maybe a language barrier as well:  the "phones" section-  what!? A bit frustrating and not especially user friendly a la programming the VCR back in the day. 

I know the RME has a great clock. Do reviewers or QC ever verify that a song is being played at the correct speed and tempo? Is there a DAC out there that has this adjustment that can slow down or speed up a song? - kind of like the turntable speed dial. Just curious.

I switched from the cheap wallwart to a 12v Li battery and the improvement was nothing less than astonishing. Whether the wallwart's feedback back into the mains played a role I cannot say.  My wallwart is plugged into my mains 24x7 as I use it to charge the Li battery when not listening, so there has to be more than just that.

Perhaps the wallwart causes less issues when it does not have a load on it? I'll pull it out and see if I hear a difference.

I did try a friend's linear power supply and it doesn't match the battery. I think I left the wallwart plugged in while using the linear power supply but I cannot say for sure. 

Long story short, the battery beats all comers. 

Pauly, can you post a link to a(or your) audiophile battery, maybe one for sale? Let us know if disconnecting the battery with the stock PS made a difference. I'm thinking it would.

BTW, the manual for the RME is a great read. Does not feel at all like Google translated German and it is sort of written in the first person on R&D issues.
