set up with M3's in surround and a velodyne cht10.Used the Yamaha rxv3900 YPAO set up for 5 positions. Put on The Wall and listened to a few songs. Honestly tingles went down my spine. Fantastic sound!!!!!!!. Thank you Axiom! I was a little concerned after unpacking the M22's the were smaller than expected. Concerned no more! Heading to work but anly thinking about getting home for more.
