Best sounding headphones you have owned?

Would love to try out the JM Audio headphones. I hear so many good things about them, never seen them in person though. Seem like a killer deal. I'm loving the Raal headphones and am tempted by the new Immanis or Magna models but the pricing is a bit much. 

I recently upgraded from the HiFiMan Sundara 2020's to the HFM Ananda Nano's...
 OMG,where my iBasso SR-1's are like the finest 300B SET amplifier driving Sonus Faber speakers,the Nano's are complete polar opposites..
We're talking big Krell Class A amps driving huge Magnapans here..I can go from the baddest Classic Rock/Electric Blues/Reggae with the Nano's,to the sweetest, honey dripping Classical/Jazz/Pipe & slippers music with the simple change from 1 set to the other...Audiophile life can be pretty awesome,even if you can't afford mega $ gear!

Just recently got the Modhouse Tungsten DS with the Enleum XPA-23RMH amp, and that is a superb pairing. They sound much better through that amp than my Susvaras do, and like the Susvaras, they sound excellent on my DNA Stratus tube headphone amp. They don't have quite the detail of the Susvaras, but overall, I enjoy the experience with them more.... 

@freediver  Congrats, and I think I know what you’re talking about.  I was looking to upgrade from my HE400S and the Sundara sounded pretty much identical, but when I heard the Arya Stealths I had the same OMG reaction.  It was total next-level performance, and I’d bet your Ananda Nanos are doing a lot of the same things.  Enjoy!!!

I’m just dipping my toes into desktop/headphone audio with Focal Clear and Audeze LCD i4 matched with a tube dac/amp and AK DAP which I can use as a desktop SS dac/amp
