FIY, the Tape does NOT use an EST. It uses a magnetostatic driver + dd.Yes, for now, I feel I'm very saturated with the offerings in the sub $50 bracket and I've figured out what my preferences are. As my current collection gives me great diversity. Maybe in future I'd get something in this realm which is exciting and path breaking. Also, as you mentioned, at times it is necessary to move forward, I think this is a good time to step-up and see what the Western 'budget-fi' has in store for me.
Thanks for the recos, but I'd like try a planar and probably an EST if it ever trickles down to this price range apart from Tape. Starsea is the one with tuning switches right? I have them in my radar as well.
If you want a sonion EST (technically only an electret, not an electrostat either) you will probably need to wait for a few more years. As the cheapest iem with them right now is the Dunu EST112.
