FWIW, I see what I believe to be other weaknesses in your system besides the speakers. IE, you have no sub listed. That may be what you need to make those speakers sing. Two is better. But It will make your mains sound much larger with a bigger sound stage. There is another item I might change also. But not the speakers until you try a sub, preferably REL IMO
That said why do you think your speakers are the weak link?
