Clearaudio Maestro II vs Grado Reference Reference2

I currently use a Clearaudio Maestro II and am curious about trying the Grado Reference Reference2. Does anyone have any experience with the difference in sonic qualities between the two?

I have owned several Grado cartridges in the past and loved the quality of their sound. I would like the try the Reference Reference2 in my system but that would be a rather expensive experiment and I have a gut feeling the the two - the Maestro and the Reference - might sound somewhat similar with a similar soundstage.

Any comments?
