The HFT and ECT might not look like much, but they will make your speakers disappear. You only think they sound good now. These things won't change the fundamental character of your speakers at all. They will sound exactly like they do now, only with greater clarity and better imaging in a deeper, wider sound stage. You will hear improvement from the very first one, and more only keeps adding until by the time you're doing the speaker kit the speakers are even more invisible. Search around you'll find threads with a bunch of people with the same glowing comments as on the highend-electronics website. Perfect time right now they're having a promo all through March.
