Bill,
You need to experiment with your MP-1 loading. I've run as high as wide open (47K - no loading resistors) with an XV-1s. On other phono stages with the XV-1s, I've run as low as 35 ohms.
Tri-Planars, Moerchs, Taleas, and a few other arms come with multiple counterweights.
If you use a heavier combination of weights, closer to the bearing pivot (adjusting for desired tracking force), you'll have a lower effective mass than by using a lighter weight combination located farther from the pivot.
Listen for bass tonality, and adjust accordingly.
Lastly, your dealer should be able to guide you through this. If they don't know the answer, then I'd contact Joel Durand so that he can educate them.
Trust your ears.
Cheers,
Thom @ Galibier
