Thats a hard question to answer because I don't really know what your listening priorities are. For me, the upgrade will be worth it in my system. The difference between my current setup, which sounds good already, and the system using the EX-8 is significant enough to do the upgrade. My Harbeth's responded really well to to the increased bass, air, timing and resolution that the EX-8 offers.
I would suggest you hear it yourself to decide if it's worth it but I think you said it in your post, "I do not see the need to upgrade". I suggest if you are really happy with your sound now, stick with it and enjoy!
