Why does R2R DAC sound better?

I've often heard people claim that R2R DACs produce superior sound quality compared to other digital-to-analog converters. But why is that? Could it be because of the way they convert digital signals into analog? Or is it due to the components used in their design? I'm curious to understand the technical reasons behind this perceived improvement in sound quality. Does it have to do with reduced distortion, improved linearity, or perhaps some other factor entirely? As a cryptocurrency and finance professional, I'm not too familiar with audio technology, but I'm always eager to learn about new and exciting developments in various fields. Can you help me understand why R2R DACs are so highly regarded in the audio community?
