Gustardx26 pro vs RME ADI2FS

No doubt the RME choice of power supply is not critical ...

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.

The battery I used was this one  Amazon.com : TalentCell 12V Lithium ion Battery PB120B2, Rechargeable 38400mAh 142.08Wh Li-ion Battery Pack with DC 12V/5V USB Output and Wireless Charging for LED Strip, CCTV Camera, Mobile and More : Home Audio & Theater

I have to admit I never read the manual other than a cursory glance for the basics

@ pauly "neither has output transformers” 
removing transformers is good thing! good transformers in sound path will cost you a fortune, and results are still worse than avoiding them all together.  

Do not understand why a person would want to modify such amazing devices built, designed, and financed by a team of wizards and think that changing their power supplies will make it “better?” Do they not think such ideas were not already considered and debated ad nauseum by the manufacturers. These are expensive product, why cut corners on such a critical feature?
