Yeah I don’t get that either. In fact I’ve never heard of a speaker not liking a lot of power. It’s just a load, it takes what it wants..Hmmm. Not sure what you mean by this. They certainly don’t need a lot of power because they are so efficient. My Cornwall iii’s play absurdly crazily obnoxiously loud with less than 20 Watts. I suppose if an amp is very powerful and has a very high noise floor, then a lot of power may be a disadvantage. . Thankfully, my 200 W amp produces very little noise. With no source playing and the amp turned all the way up, I have to put my ear right next to the tweeter to hear any sort of hiss
In any case they sound lovely with 100w/side of tube power via the cronos magnum ll. Do look forward to trying them with 30w of class A via my m-22 though
