my new m200s came wednesday afternoon,and where set up shortly there after.they are suppling my mains,which are polk rti800s.they are great.i can hear a difference in the adcom amp and the outlaws amp. the adcom sounds better for surround,but the outlaws rule when it comes to music. maybe it's the way i have my room set-up,or just my ears.now i would like to add a 3rd outlaw m200,for my center channel.life is good.can not wait to get home and play my music. i'm playing music i haven't listened to in months. still not sure about surrounds or bookshelf speakers,or company, polk,def.tech. etc..listened to def. tech 7002s,outstanding sound. i listen to mostly heavey metal,rock,some southeren rock.
