If you're talking about going to a pair of the original SC-IV's, my opinion is that you're not upgrading to anything life-like.
I owned a pair of the original Dunlavy SC-IV's (bought them when they first came out) for eight years. For the first three years they were on my stereo, for the last five they were on my HT.
I replaced them in the stereo system with a pair of B&W Silver Signature's. They didn't have the bass of course, but they were much more realistic and natural.
The SC-IV's will easily slap your chest with the bass, but the midrange is not as natural as many other speakers.
