Crossover component upgrade, DUELUND????

I am in the process of researching the components in my Dunlavy IVa speakers and have narrowed my choices down to two companies. I am looking at Mundorf M-CAP SUPREME and M-CAP DILVER FOIL IN OIL caps. I am also looking at Mundorf for the MOX resistors.

The second company I am looking at is Duelund Coherent Audio. They make a GRAPHITE RESISTOR specifically designed for crossovers. They are able to build the resistor specifically to replace my speakers parallel resistor values with one component rather than the 2-4 pieces presently used. This will (somewhat)help offset the very high price point for these resistors. These are sold through Part ConnecXion and factory direct. I have been speaking to the factory and we are also discussing their very different design for capacitors. I am presently waiting to hear back on the cost for the values I require.

While I wait, I was hoping that someone might have some experience with these products. I am very impressed with the design concept behind both the graphite resistors and the flat foil capacitors.

Sherod, another explanation for what you are hearing is that in general Hovland caps have a slightly forward midrange.
This may be perfect in the right system or could be a tweak opportunity, if the system's midrange bites.

I see I never did finish this discussion. I instead wrote a full review on my crossover modifications. Please check it out at http://forum.audiogon.com/cgi-bin/fr.pl?rspkr&1164387495

Pedrillo, keep us informed!

Pedrillo,
I also just ordered a pair of the polyester-in-oil version to experiment in my tube preamp output couplers. Here's a link of some reviews on the Tubestore site where I purchased my caps:

I was wondering if anyone ever upgraded the inductor in their speaker?? I am considering the duelunds since they have done extensive research in their products. Any thoughts? the speaker merlin vsm, I am doubtful that what's in there is of poor quality so it's a gamble.
