For fit and finish, I think I had one of the first sets of xm9's. Bought four and never looked back, sounds great, plenty of mid bass , clarity and power. I keep them under cover almost all the time and they are in sox indoors over the weekends. I could not be happier, I have not heard Ws up close and personal. I did love my Ws 420 eq and had good service from the mfg. it got sold with the obv 2007 . Cant go wrong either way. Sell the pro 60s and buy the icons or sell the whole setup and be Texas different and step into 4 xm9's.
