I own a 501 and can’t answer your question. It’s a heck of a digital front end
WEISS 501-502 DAC
I believe the Weiss 502 Dac came out in 2017. Does anyone know if there have been any up-grades to that unit since it's release date? in other words, is the current unit the same ,or have there been any sonic improvements? Thanks for any feedback. Sam
