Interested in the new Maggies (four MMG-W and MMG-C) and a powered sub. Understand Maggies are about 86% efficient with a 3-4 ohm rating. I also need new electronics. My home is pre-wired for stereo in four other rooms. I'm interested in a 7.1 system (5.1 HT and a second zone useable for providing music in these four other rooms). Before hearing about these Maggies for my HT I was thinking 75-100 watts per channel (@8ohms) would meet my needs. What receiver, amp/pre-amp or integrated amp is available for less than $1000 that you have or consider a good source for these Maggies?
