Volleyguy, the question becomes-- given other constraints in the Klipsch-- how far is it worth taking these speakers without looking at new drivers, or even more fundamentally, evaluating the absolute potential of Klipsch relative to more recent stock or tweaked designs. I know it is your mission to find out how far these speakers can go. But at this point, if the thread is worth continuing, it would be nice to hear your praise of Duelund in context of the running costs of the Duelund upgrade, and in context of all other components in your system.
For example, in my own(balanced) system, from end-to-end I have substituted about 16 critical coupling caps (V-Caps TFTF & Mundorf Silver/Gold) in four line-level and amp components-- and I have yet to experiment with the speaker cross-overs. Notwithstanding your advocacy of speakers & source as making the greatest difference, all these changes in caps were "revelatory." So I'm saying look at the system as a whole. As expensive as these crossover parts are, if they come to as much as 25% of total system value, then doubtless you're missing major opportunities to make meaningful upgrades elsewhere.
