The only ones I liked were the original HE1000 and the HE-X - All the Anandas, the Aryas (minus Organic,) and Edition XS all had SOMETHING in the treble that ruined the timbre completely and I couldn't listen to them long. Ananda, Arya, Edition XS, and even the original HE1000 suffered of this to some various degrees: There's always something slightly plastic, polite or even aggressively metallic about the overall sound. For ex, I would not listen alot to IAMDDB cause the slam don't boom enough nor the rumble resonate enough, the bass of HE1000 is too well controlled to offer loud rumble release. Those note hit without edgy brightness to definition, its smoothly rounded and dense in it's release that envelope the listener with colorful resonance highlining tone color with air vibrancy.

In the same vein a stealth bomber’s shape and form which is not a random or artistic choice at all, and ensures deflecting or bouncing off radar waves and becoming unnoticed, HIFIMAN’s stealth system ensures magnets not being in the way of the sound as good as possible. The bass is cleaner, faster and leaner with the Audivina, bass line and kick separation is better and less thicken by warmth, overall bass is thinner but have more fine details in term of texture as well as attack edge. The Soundstage is way wider and taller with the HE1KS, sens of depth is different though because your part of center stage while with Audivina your more like in small studio room with centered monitor speakers, for ex, HE1000S remind me my big Magnepan MG02A planar speaker which embrace my whole sound perception scale. I’m sticking to the Hifiman name and we’ll be comparing to the V1, V2 and SE (also a V2) later in this article. However, at the same time, that makes the instrument separation top f'ing notch, and it handles normally claustrophobic music (which, let's be real, is most of what I listen to with the metal genre) excellently.I wonder if he got a bad HE1000Stealth, Monitoring is easier and more accurate with Arya due to cleaner separation and edgier definition of them. He's a big fan of tube amps and custom inear monitors and has published hundreds of product reviews over the years. HE1000v2, improved version, cups are not as deep, everything tighter, more seamless in build, thus less interactions on the way out, more "window shade", still soft and diffuse but cleaner and better attack. This texture isn't hearable in real life, and think about how non amoplify cello should sound and blossom is natural air and it's how it sound.

World’s First Diaphragm in Nanometer Thickness: The diaphragm in nanometer thickness is extremely low in mass, yielding faster response and lower distortion. When an headphone can deliver full bodied presentation with natural timbre for both piano and female vocal, I know i'm into mid centric territory that doesn't forget their fundamentals harmonic hidden in lower mid range. The cello sound marvelously full and natural, it's vibrant in it's release and soft in it's attack, the presence is wide and enveloping not compressed or just about dry imagie of the sound, it trrigger lot of emotional response which can be kill with a rendering that will over boost the texture of bow stroke. I always had a sweet spot for the Sundara musicality, the best Hifiman planar in term of high sound value in my opinion.The sound - the most important part of an audio product always being whether what comes out is digestible after all, is world class. The Audivina is notably more technical and neutral sounding than more laid back and natural sounding HE1KS.
