Do you find battery supplies inferior to well designed power supplies?

I have to ask, because every single battery powered unit or battery supply I have ever tried sounded great for the first few tracks, then focus gets blurry and things sound lost. This has happened with every single battery powered audio device I have tried. All of these devices are regulated as well, and really kind of have to be, but I just never got the consistency that I get with Linear Supplies and or well designed switch mode supplies, for example.

Fresh charge, sounds great, play awhile, things get lost. This is battery powered DAC’s, Hubs, Battery Power Supplies with SuperCaps, etc. I only have experience with digital products using batteries, which is why I posted this in Digital forum.

Look forward to your experiences and thoughts!

Batteries that have a amperage capabilities should always be better than any made up mains powered supply.

There is only one reason I can think that yours did what you said, is if their were no voltage regulators after the batteries and the after a few hours the voltage dropped and as a result so did the circuit ideal operating parameters.
