Paul, congratulations from me too. You should have some fun trying them out with your two systems. There is a lot of good information here by others on step up and break in. I started with the 1.7's and was very happy with. Listening to Graham, Ray and others talk about their 3.7's drove me crazy. I moved up to 3.7's and they moved up to 20.7's. Thankfully those are out of my reach and my room is to small. I sure love my Maggie's
