Hi, I own both the MMG's and 1.6's. The 1.7's will be a huge step up from the MMG's but they will need more power to sound their best. As you go up in power and current, the dynamics drastically improve. You may want to consider going up in power before upgrading the speakers. If you listen at low volumes, then take you integrated amp to the store and give a listen to the 1.7's to see how they sound and how loud they play.
