I have the 1.7’s and am satisfied with the performance of the Odyssey Khartago which is rated at 110 into 8 ohms. The Maggie’s however are somewhere around 4 ohms impedance. The amp is stable driving 4 ohm loads and sounds amazing. However you’ll also need a preamp and possibly a phono amp to accompany a TT setup.
Klaus at Odyssey is quite familiar with the Maggie Khartago combination. Contact him for advice.
