A new favorite planar. Astralis vs. MP145 Pro vs. S12 Ultra

I first heard the original Letshuoer S12 about five years ago, and ever since it's been my favorite planar IEM under $200. That is, until now. Three new planar IEMs have come out recently, all priced under $200, and one of them -- just one! -- is better than the OG S12. Let's talk about it. See the Letshuoer Astralis on...
