Gumby never had official revision. However with new components, listener experienced some change in sound signature and hence this revA2 came in pic. So it’s unoffcial revision. I guess if you check the back panel of your DAC, it will have serial number. If it starts with “A” then you have A1 else A2.I'm confused (easily done I admit). I thought the Gumby's slight revision change was due to the unavailability of a couple components that were not in the listening path. Not like the Yggy Analog2 upgrade. Can someone set me straight? My Gumby was purchased in January of 2017 and does not have a letter (A/B) associated with the serial number. How can I discern what revision it is?
But again as far as schiit is concerned there is no A1and A2 for Gumby.
