unfortunately I don't have that luxury yet. I received another 2-27's and 1-24 today, used but tested good (according to seller). Substituted them and slightly louder. However, still hear a low buzz in the background. I also switched around the 24s and 27s to see if any difference, which there was none. It sounds very clear, but it amazes me how much weaker channels that the 84B picks up that the 90 doesn't. Is that just because the 84 is regenerative? - does that make it amplify weaker channels better?
