Frederik in my test which of course is only my one set of speakers. I could mix and match vintage foil in oil in one speaker and Duelund in the other and listen to both speakers. As soon as one speaker had plastic caps and one with the vintage foil I could listen to only one or the other speaker at a time. It was almost like they were out of phase.
Also when a plastic cap was put in for the midrange and Duelund for the tweeter and the signal goes through midrange cap. The Duelund did not give the same improvement. (yet the Duelund did when used with the vintage foil midrange cap)
By far the second best cap was the original foil cap in the midrange. Again no plastic. Many Klipsch fans say the AA crossover is the best I often wonder if it the foil caps they used then. Newer Klipsch crossovers used plastic (industry norm) and do not have the following.
I have yet to hear a customer of yours not think your caps make a natural sound.
My modern SS amp did not make the same improvement using Duelund as the vintage tube amp does either. My amp of course was loaded with plastic caps.
There is also a large following of vintage guitar amps, (my tech guy who plays guitar would have nothing but vintage tube guitar amp) vintage stereo amps all with no plastic as a common thread. The thing both vintage guys will talk about is the tone!
I do want to thank you as I have yet to find a downside to you caps.
My gut says and I am going to find out if your caps do the trick in a vintage amp. My gut says a vintage tube amp with (no plastic anywhere almost) and a set of Duelund coupling caps will blow me away. All the "real feel" of the vintage/foil with a massive noise reduction to really let you hear what is going on. To me your caps are the best of both worlds.
