The isolator is a use once affair, as you cannot get new glue.
I have not compared the Houdini directly, as I don’t want to peel the isolator off the Music Maker Classic it is fitted to.
I do know that the Houdini works well, but I have never heard the MM without the isolator, so I don’t know how much it adds to the great sound of this cartridge.
They have the same function, but they are vastly different. The Funk is more complex.
