Got some time at the audio show to compare these bad boys side by side with two of the same model Auris fed with the same source, for quick A/B’s. Also brought my Massdrop THX 789 as my reference (it really rocks, even with Susvara it’s pretty darn good!)
As someone who recently upgraded his HE1000v2, but never had the chance to compare because of the send in; I can say with certainty that the HEKse is a worthwhile upgrade. Sounds more focused, transparent, and faster - however you gain a bit more treble energy and your midbass is less bloomy and more snappy. However, it is very ruthless, and perhaps the least enjoyable with rock of the bunch.
Empyrean I’ve heard briefly when it first arrived to Canada in January , but only had a chance to listen without burn-in and on inferior amps. I have to say it has grown on me, the bass is wonderful in its impact and enveloping sound, but less textured than hekse. Treble resolve is fantastic and well layered, yet not too fatiguing. They’re more transparent than i remembered. What shocked me is that it stages wider than everything besides HEKv2, but lacks the defined imaging cut out in space of instruments that HEKse and Susvara have.
One thing I must note, and this seems to be a problem with a lot of high end two channel speaker manufacturers, audiophiles really dig bumped midbass for presence; I however despise it. The Empyrean’s have truly exceptional bass, and yes, it bloats a bit more than I like, but it’s very much so nitpicking. It’s one of the most perfect rendtions of bass on headphones. I do however find the suede pads significantly more coherent, and would rate the headphone’s bass quality S tier with suede and A+ tier with leathers due to some unwanted bloating.
Susvara.... just wow. Heard it twice before, but now that you A/B it in mere seconds, it’s apparent that it’s truly effortless. Bass texture and timbre is out of this world, but frankly, so is the entire delivery of sound. It made the HEKv2 and Empyrean’s highs sound etched in comparison; even the HE1000se lagged behind audibly in the highs timbre.
Ultimately, my preference goes as ordered in the pics, but Empyrean are neck in neck with HEKse (reference natural/ rich vs reference neutral/ ruthless). Susvara are by memory, almost as good as the HE1, and perhaps have a cleaner bass and macro dynamics. HE1 soundstaging and transparency ultimately keep it my #1 headphone, but Susvara is undoubtedly my #2.
