I have a pair of X5's. They are the most revealing speaker I have ever owned, which is a bit surprising given how relaxed they are. Any upstream changes are clearly evident. The tweeter is probably the most natural sounding in my experience. Properly setup there is a fairly narrow sweet spot, enough for two people. The tweeter's vertical dispersion is somewhat limited - you will notice as you sit down in the sweet spot how things come into focus. I am currently trying to get a more layered depth to the image. I am waiting for an Aesthetix Romulus to arrive, replacing my PS Audio Directstream Sr. I did audition a Pass XA25, which did indeed provide the depth I was looking for, but there were other issues with it, so back to my Rowland 535. Like any dipole they need to be out in the room a considerable distance, mine are ~4 ft from the front wall. All in all, they are really satisfying speakers.
