Marantz TT-15S1 anyone with experience fitting an electronic speed box?

Hi everyone,

I am curious about getting some kind of speed controler for my Marantz TT-15S1.
Not ready to get the one made by Clearaudio, (the Marantz is of course made by Clearaudio ) and looking for a less expensive solution. Not sure I need a speed box, but as I said, just curious about what it could bring.

If someone actually owns the Marantz TT-15  and is using a speed controller, please share your experience!

Thanks !
