email weiss, daniel himself will usually answer, my unit gets periodic firmware updates
i too love my weiss 501 - don’t feel it needs any improvement 😉 but we all need what we need to sleep well at night!
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
