I had a chance to listen to the Persona 7F for a little while today, playing some audiophile-approved tracks.
Yeah, those speakers just leave me cold. They certainly can sound clear especially in the high frequencies. But overall I had the same impression as the last audition - they just don't sound timbrally organic or convincing to me. Everything sounds "canned" or slightly glazed, and when I close my eyes there are all sorts of "clear/clean" sounding acoustic objects presented to me, guitar, drums, percussion, etc. But they have the same grayish tonal "color" and my mind has to really work to untangle one instrument timbrally from the other.
A competent speaker, and I understand anyone else enjoying it, but my subjective reaction is just..."meh."
