Finally getting a chance to sit down and listen to some serious chamber music. These are tone monsters. Where the Usher had occasional confusion of lyrics, or unclear which octave a trumpet was playing, these speakers lay it all out bare. I think the 1st order crossing is much of the improvement. The ceramic tweeter has more texture on upper midrange stuff than the bogusium - like a violin, you can still hear the rosin on the highest notes, on the Usher it was a rounder glow. Still no sign of treble harshness whatever. Much more detail, but less anxiety thinking about is it right or wrong? "If you have to ask..." The most thrilling part of the frequency range is lower mids. Just above the reflex enhanced frequencies it is so clear and rich in the 100-300Hz range, like cello and baritone singers. Of course the hazard with any hi resolution speaker is dealing with the recordings. Some recordings have beautiful clear imaging, others are blurred in comparison and images stick to the speakers even on newer classical recordings. But after a minute or two my brain adjusts to the new "mix", new mics, new recording space, and the music takes over. I think these speakers would like a bit deader room. I want to squeeze out every drop of information. Saw season is almost here.
