I have a mk1 toaster from 12 years ago. It does not have the true impedance feature - that was introduced with Kemper stage. It’s a feature I always wanted to try.
I contacted support when Mk2 launched and asked them if true impedance was in the Mk2 toaster. Kemper support said it was not on Mk2 toaster or rack. It is on mk2 stage.
That's right. That's why I was replying to @Ed DeGenaro . He says his toaster has true impedance, but I don't understand how that could be.
