Let me add that the first few days all I have heard of the SD7 was thru you tube videos and when I got mine a few days ago I had only played it once thru headphones and the rest of the time with the Great loud on-board speakers at home. At this point I was happy....BUT, yesterday at the Ketron Work shop AJ brought TWO Giant 100lb each Mackie speakers not sure about model they looked like
SRM 750's...when I played the SD7 thru these at Full Volume all I can say is OMG!!!

Tomorrow I start tweaking & fine tuning thru MY
Hk Audio Nano 600 PA!
