Scott. When at our Keyboard Festival last April two pro concert players used the PAS in concert. One used it also for a late night dance session. I stayed behind in the concert ballroom after the evening concert for the purpose of listening to the PAS during the dance session. I was very much wanting to like the sound after all the reports on the forums.
Without a doubt the dispersion of sound whether you were close or further away was excellent, but I had difficulty coming to terms with the mid range frequency prominence. Possibly this was due to the system not being EQ properly ?. Also the player had the volume far too load which may have effected my judgment.
Next month Sept we are attending the Keyboard Festival again and it will be interesting to see if my view of the PAS has changed.
