@gary_moresky,Do YOU feel the need to upgrade/change the Dunlavys? If not, then why think?In my case, I wanted full range sound. My previous loudspeakers were very fine, but not full range. The upgrade price was 10X the price of my previous loudspeaker.
When/why to upgrade?
I have a pair of Dunlavy SC-IV/A speakers that, as far as I can tell, work the same as when I bought them new in 2000. I would upgrade if I had confidence that replacement speakers would work better for me. But that would require considerable effort and expense, and is not something I would undertake just for the novelty effect. Over the years, I've upgraded amps and DACs, and always with positive results, but speakers seem different. How do you folks know when it's time to upgrade yours? Dunlavys, after all, have a great reputation for producing neutral sound, and I don't see compelling evidence that speaker design has advanced much, at least, within my price range.
