Moondrop has largely made their fame by creating IEMs that hit certain target responses pretty reliably - be it Harman or Crinacle's. Of course, it's up to you whether you subscribe to that target. Enter the Moondrop Para. Not their first foray into full-size cans, but I'd say that it's their best. Both are supposed to be measured on the same rig, so the curves should be comparable. I could detect the 1.8k dip making stuff sound a bit distant and the 3.5k peak adds extra spice to strings/vox/etc. It did seem like the driver is very low THD as it wouldn't break a sweat even under high SPL and copious LF energy. I could detect something strange going in the highs like a resonance but I found it pretty benign. For a 300$ planar the highs were freakishly clean. Staging is precise but not very wide. I liked the overall resolution, however I don't have access to an HD650 on one of your wet plankton tube machines. Speaking of amping. It's a 101dB/V driver, so running that thing should be a walk in the park, right? RIGHT? It's an 8 ohm load, so it transforms into a spicy 80dB/mW load at those 8 ohms. To my knowledge almost no headphone amp is rated into an 8 ohm load. My Jot2 did alright, your beefy solid state will probably also survive. Chip amps? Probably not so much. Tubes? They'll love it on the TX 8 ohm tap!
