Most of the brands I mentioned are not too well known outside of forums such as this, so don't feel bad

That's how I found out about them. I've heard the Gallos, and they sound pretty good, the Due is much better than the Nucleus thanks to the tweeter. I've been pretty impressed with Mordaunt Short, which is why I use a pair myself. The ELTs are respectable too and have a big following, but I haven't heard the Tykes myself.
