Coupling capacitors give warm & sweet sound

Piedpiper,
The dynamicaps are in fact some newer revisions, and they use to be the TRT caps not even named Dynamicaps, which by the way are branded made by Wondercap anyway..

I have used them with better luck in the electronics than speakers if that helps. More "Shout" from some speaker drivers from my experience.

The DynamiCaps are indeed descended from Wondercap through about 4 iterations but are actually made, as are the Cardas and many others, by the gentleman from Running Springs.

Thanks again for sharing your experiences.

My experience with Hovlands do not mesh with others here but I'm not disagreeing with those opinions. They took a long time to break in, however. I think they are a good choice to slightly modernize the sound of vintage equipment without going too far. Caps of this ilk are also a good choice if heat is a concern. I think the Hovlands are probably not a good choice on typical modern amplifiers...most of which strive for immediate wow factor at the expense of long term musicality and enjoyment.

I really think the only solution with these caps are to try them yourself and give each cap enough time to run in. Expensive and a hassle, I know. Also, it's not the specific cap that matters alone, it's the marriage of all the parts.

While Hovlands never sounded right for me in LS, large Hovlands sound extraordinarily good as stock crossovers in Merlin speakers. One reason could be that the caps are cryo-treated. I wonder whether cryo treatment would close the sonic gap between some "premium" caps.

Undertow,

just in case my last post wasn't clear, Peter Moncreif and his associate at Running Springs are continually changing the recipe. Every time I've ordered them which is many many times over the years, they are slightly different. Sometimes the name/branding has changed, such as Infini Seti Signature to DynamiCap, sometimes it hasn't. Evidently, there is a brand new version that is now being used by Aesthetix as mentioned above. Incidentally, I usually remove some or all of the tape on the ones intended for electronics. I also run them in before installing them so I can get an accurate assessment.

Just FYI.
