I thought the tonality was reasonable, and with some attention and experimentation, had potential.
My problem is that the speaker totally dissociated the performance from the listener. It was like the musicians were placed on a pedestal, behind 2 inches of plexiglass. The sound was clear and 'accurate', but it had no soul. The sound was not relaxed, effortless, flowing, or beautiful. It did not pull me into the performance. The focus was the speakers, not the music. Although the speakers 'disappear' from a soundstage persepctive, they did not disappear from a musical perspective.
This was with 2kW of amplifier muscle, so not an issue of more juice needed to have them open and sing. Also used was a tubed preamp. There may be an amp-preamp-cable combination which could work, but it would probably be a challenge.
