Here’s reality in my view. No one knows your room, your gear and most importantly, your ears and personal sonic biases. So regardless of all the well intentioned input and advice, your choice (absent an in home audition before purchase) is still an absolute shot in the dark.
So it begs the question. If you like what you have, why are considering a change and what are your expectations if you decide to proceed with the change? A different speaker will sound different but not necessarily better. "Older" does not imply substandard or inadequate. Unless you have an absolutely compelling reason to "take the leap", don’t do it. Enjoy what you have (as you apparently have for numerous years) and enjoy the music. Common sense is often underated these days. Good luck.
