I've not used the newer Audio Note tants (yet), but I do have some sitting here that I'm gonna slap in a new preamp pretty soon. Since it's a new build, I unfortunately won't be able to A/B then with another type.I've used tons of the (now discontinued) Shinkoh tants. I haven't found anything I like as well for grid stoppers, although Rikens are definitely #2.
