Interesting. What did the Arendal's replace if I may ask? I know for me, moving from the air-motion tweeter in my GoldenEars, to the waveguide dome tweeter in the 1528s, required adjusting to a wider "sweet spot" and increased blending with the midrange. The AMTs were "sweeter" up high but the domes sounded much more natural and had the "sound power" in the upper midrange was noticeable. I can see why you felt they were "shouty", but depending on what you came from, might just be giving you those upper mids you've been missing.
