Hi,I would like to make a comment.As for the Isis vs the Diamond it is a whole different world,It does everthing better.I could fill a page with the differences but the only thing I would not do is put the isis in a room that is say 12x20 or smaller,it will play fine but you will not get the most out of them.Electronicbliss is right placement is everthing and also when they are in their final position and toe-in is right you should laser level them,it makes a big difference.I have heard most of the major contenders and none have tempted me to change the Isis,the only speaker that is interesting is the rockport altair,which I have not heard.All the big speaker have their strong points but to me none sound more like music then a properly set up Isis.
