I have to say I love these cartridges, and these cartridges love unipivots! But I find the Grados perform best on low-mass tonearms (the best results I ever got was with the ultra-low-mass Black Widow), where the infamous Grado Wiggle completely disappears. But they still sound great on medium-mass unipivots. You'll love it, if you love gorgeous midranges. And contrary to a lot of comment, I find both the high and low-frequencies quite good when the Grado is matched to a sympathetic arm. The Grados do things that remind me of tube equipment, and I believe, anyway, that it takes tube equipment to hear what the Grados have to offer: which is unmatched retrieval of such things as instrumental decay and resonance, due to its very clean sound, due in turn to the lack of resonances of its wooden case and potting. I use a high-output Grado Platinum (all the names confuse me) into my tubed ASL Mini Phono, and it definitely does not overload the preamp, which is also somewhere around 40db. A high-output Grado, while likely slightly less refined than a low-output versison, will also have more dynamics and power. And the high-output version is no slouch at information retrieval. Good luck whichever way you go.
