One of the reasons I'm trying to expand my reach of opinions is that no one there seems to have actually used the Classic Remix. I don't deal with Kevin Deal directly, and the couple who are familiar with the line there whom have answered only know the Legos and higher. They did say that they hear it, and even hear it on the Primaluna, which also uses relays.
But I also read a review of the Legos on Positive Feedback that mentioned silence switching between inputs.
