As previously stated, I think you're missing the boat in not defering judgment until much further into the break-in process. However it's delightful to hear that the experience has salvaged speakers that you were considering selling after three decades of ownership. Very few on this forum realize that a few hundred spent on mods may avoid tens of thousands in equipment churn. When those Klipsches were manufactured, the hobby was full of tinkerers. No more.
To Raul's point about neutrality: I started with internal mods to my CDP source, and continued modding progressively downstream as best I could with each component. I was first convinced that the source was the most important component, then later the preamp, then later the amp, and so on. Of course they all are! Do the best with each one, and with such high-quality piece parts you will probably find when finished that your system has achieved transparency & neutrality.
PS: I'm still trying to recover an original pair of Altec VOTT that I foolishly sold to my brother in 1977 for $150.
