B_Limo,
What, i believe, John (Jmcgrogan) and I (and a lot of others) are trying to tell you is this: "Stop what you're doing and start thinking about the big picture!".
Forget about your room, as important as it is, for right now and think about your components. You like the KEFs in Steve's system, so you bought them. You've heard what the KEFs were showing you in Steve's home, and you hear what the KEFs are showing you in your home.
Besides the sound's interacting with the room's acoustics, the speakers are giving you the music that they're receiving from your components. They can't give you gold from iron.
You said that your components are not as good as Steve's, and that Steve has taken them even further with his mods. Turn on the light bulb, the KEFs are showing you that your components aren't up to making music like Steve's components.
Now quit buying speakers and start comparing Steve's components to yours and spend your money upgrading those pieces that can't handle their share of the load.
You need to sit down and be honest, and come up with what you can spend and take the time and spend wisely. By components I mean every piece of your system from the wall to the speakers.
