Everything that comes from the 4367’s horn has snap and more inner texture. The notes are much more separated. The 590s horn is dull and splashy with no life in comparison.
This has been my exact experience listening to my 590s after purchasing and listening to my KLH 3s and 4305Ps over the past year. I thought maybe it was just that I was getting "bored" of the 590s after 4 years of ownership but no, they just don’t deliver that sound as you describe it, and it makes them sound lifeless in comparison (even with those big dynamics and soundstage...)
Thank for your running the test. I’m doing the AB of my KLH 3s and 4305Ps tomorrow. If the 4305Ps get the same result in the same room as the 3s, I’m going with the 4349s. If not, probably leaning Borresen.
