playing them for fifty hours or so and their sounding very good.the highs are smoother the mids are clean and clear and now i have very good bass.just seems like they are a more balanced speaker.bigger soundstage .more open .clear from top to bottom.i no longer need my hsu 3 sub the bass changed that much.i running them with a jolida 801 and am looking to upgrade to seprates. i need a good tube preamp with remote .already tried one without one ,and 100 watt or so tube amp any idea would be appreciated. thanks again deang for the fine work you done
