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.

I'm curious what the break-in is like for the new Claritycap MR. I have read from one user that it has a very quick break-in compared to other film types. I just tonight replaced a pair of Hovland Musicaps in my preamp outputs with a new pair of these Claritycap MR caps. After a couple of hours, they don't sound too bad, but the mids are a bit recessed compared to the Hovlands.
Thanks for the feedback. They only have about 16 hours on them in my preamp and I can already hear an improvement.
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:

Pedrillo,
Read through the posts on member Dgarretson's system. He has extensively modified his Merlin speakers.
