That's about $5500 USD. So maybe there IS a bit of competition for the Audya.
It will all revolve around the styles again, though. Unless the Wersi styles make a BIG leap forward in contemporariness, I doubt, despite this no doubt having the technological advantage over Ketron (OAS has no trouble streaming multiple audio channels, just for starters), it will still fare poorly.
