Not shrill or piercing, but sparkly indeed. Reminds me of the top end on the Ultrasone Pro 900 prior to burn-in. I'll keep them running and report back if anything changes. They seem to have calmed down a little bit but I might just be my ears getting used to the sound. I'll switch to the 4.Ai now and come back to the 3.Ai later 
Just to clarify, are you already using the Magnus cable with the universals, or the stock cable?
