Possible endgame IEM below 1000$

I just can't stop bobbing my head with these IEMs and any music genre I listen to comes to life, Just perfectly balanced across the frequency spectrum, the only drawback might be that it might not be as enjoyable for bass heads. The bass has the quality and produces the bassline just as the mixing engineer intended for it to be, the quantity and thumpy feeling might not be as audible on tracks that lack bass in the mix. Mids are just perfection, though I personally found that some brighter mixed tracks came off a bit harsher than usual at times, my counter to this was using final audio E type tips and a warmer DAC amp (LP W2). Treble is airy and snare hits and cymbal hits are crisp, I usually test this on the Limp Bizkit 'Significant Other' album. It might possibly be the best quad driver set out there for the price, I know sets like the Monarch MK2 exist for $1000 or so but these for $619 is just excellent value, Compared it to the only other detailed set I had 7hz timeless, the 7hz sounds less detailed but has more speed in the bass and kick drum hits, the mid and treble region on the 7hz is blunt compared to the Kinda Lava. I guess this is it for me and will only look for a decently tuned Planar in the future since my 7hz is gone to newer ears.
