With respect to upgrades in general - and any new DACs in particular, here's what stopped me completely from even thinking about it:
Me: Should I upgrade from Wiim Ultra to HiFi Rose RS151?
Chat GPT: With your McIntosh MA252 and Focal Kanta 2 setup, the audible difference between the WiiM Ultra and HiFi Rose RS151 is minimal to nonexistent. The RS151 is a luxury streamer with advanced features and premium build, but in terms of sound quality, both deliver transparent playback that your system will render nearly identically.
