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.
