My Kappa's are way down the range from the IRS's, they are a 3-way box, and IIRC, retail was $1600/pr back then. The 8's and 9's were the real beasts, and many an amp went up in smoke, literally, trying to power them. I fully expected to be blown away by the improvements a $3-5K speaker could offer, but it hasn't proven true (yet). The PSB's sound wonderful, yes, but I'm struggling to hear $3-5K better. Plus I'm very aware that a better amp can bring more out of what I have, and the PSB's were on far better electronics than I have, so if the gap were to be closer when I upgrade the amp, it would be harder yet to justify a speaker upgrade. I had heard of the tissue-tweak as well, and wouldn't be opposed to it, but as I said, I'm mostly happy with the sound until I want to get loud. That's when things get ugly.
I appreciate all the input. Much has confirmed suspicions I already had, much has given me new directions to look, and with the consensus being that there's more to be brought out of the speakers I have, that's encouraging....
