Kurt, my friend, I have empathy, but I've never experienced you problems myself, so I can't answer from experience; however, I can't help but think that gaining in comfort and listenable dynamic range would be paramount in a situation like yours. I wouldn't think of that as a step "backwards", but rather a confirmation that your experiment with the new speakers failed. Nothing ventured, nothing gained, eh? There's no sin in a failed experiment unless you refuse to acknowledge the failure and learn from the experience.
Good luck finding a solution.
