It took me longer to fall in love with the UA than I expected, but I think that's because I was trying to make it do something I wanted in a way that it wasn't prepared to provide. Once I rolled a few tubes through it, used my ears instead of my eyes on the eq, and faced the obvious fact that how it sounds in the bedroom isn't how it sounds on stage... we started getting along much better.
