I have no experience with that cartridge, however many on this forum have spoken highly of it within it's price class. Not knowing anything else regarding your vinyl system, considering this cartridge, I believe the phonostage within the Rotel pre to be a weak link. That said, if you found a line level preamp you liked, you could still could use the phonostage within the Rotel until you identify (afford) a outboard one.
Regardless of system expense, balance is important, a single exceptional component will not be truly appreciated, one component as a weak link sets the standard throughout.
