Thanks a BUNCH CoiL! So that tells me that the biggest issue with the ATE was the port not being large enough, and they addressed this on the ATR (as it has a pretty substantial port). The ZST's is pretty substantial as well.
I still love my open grille mod ATE as well (thanks to you).
I plan on grille modding the ZST one of these days to see if any additional gains can be had, so I'll be sure to post any significant results.
1. Do nozzle mod too for Your ATE (with ED9 brass nozzles) and You`ll love them even more
2. ZST with grill mod could be different story than ATE/ATR improvement and I suspect it will be actually worse. Most improvement regarding ZST highs could come from moving BA further inside shell and using proper damper for BA. But tuning the mids better is very hard thing to do.
Better dynamic natural mids and huge airy soundstage are the things that I like more with ATE than ZST.
