HarmonicDyne Zeus - Linsoul Audio

Harmonic Dyne Zeus + iBasso DX220MAX (350 USD + 1880 USD) – Dx220 MAX is just the type of DAP that can put a ton of punch into the Zeus, but still make them musical and wide. The sound is really powerful and controlled, with a ton of sub-lows and impact, a warm-ish midrange, and a ton of space. The treble is somewhat smooth and relaxed, but really detailed, while the midrange is juicy and vivid. The Zeus has an identical angled driver position as the Helios, and as a result, actually does have a decent soundstage and sense of space. Certainly, the sound is more spacious than my modified HF 580, which sound somewhat closed in by comparison. You defined the HDZeus as co-equal to the most universally favored set ofHeadphones ever created within the History of sound. With the more extended treble range, the Poseidon presents an impressively delineated and accurate imaging presentation. This allows the images within the soundstage to be separated with a layer of air between them.

This section is going to be very reminiscent of my Helios review, as the basic design and materials of the Zeus are a recycle of the Helios. The walnut wooden cups are the standout feature and are smoothly and perfectly finished. The walnut wood cups are perfectly manufactured. Applying a 1/12 smoothing, I am getting this graph and as you can see, the sub-bass is good, mid-bass is absolutely perfect clearly standing out, midrange is mostly linear but it sees a gentle slope until upper-midrange is hit with a roll-off. Treble is calm and relaxed in the most sensitive part (between 4 and 6 kHz) and immediately after that it gets higher momentum and becomes much stronger and defined. There is a lot of presence in the top octave that gives an impression of a detailed and transparent sound. As you can see, Zeus was tuned towards an enjoyable experience, in detriment of a super-linear, super extended frequency response. The first thing that I noticed with the midrange is that it is relatively forward sounding compared to the rest of the frequency spectrum. While already being forward, there is a small injection of euphony to the midrange, allowing vocals to have a measured amount of richness. I will briefly touch the subject of their sensitivity and how much power it is actually needed to fully drive these at maximum potential. According to the Benchmark HPA4 and to the microphones inside the MiniDSP EARS system, power requirements are by about ~12 dB higher compared to Kennerton Magni and Gjallarhorn, resulting in a sensitivity of around ~100 dB. Since these are as loud as a Fostex TH909 and Kennerton Vali, their sensitivity of 100 dB per 1mW of power mentioned in the manual is very accurate. Entry level planars like Audeze LCD-1, Hifiman HE400i are pretty much on the same level power wise, Quad ERA-1 is more of less the same also. Going up into the mid-bass region, there is a hump that gives midbass instruments some emphasis and allowing drums and bass guitars to have some weight behind them without being overdone.

Zeus has a clean midrange performance; it starts very strong but it isn’t elevated at all. Its neutral to me and doesn’t stand out very often. Voices were rendered pretty nicely with an unmistakable pitch between male and female voices, but in terms of frequency response this is probably the least impressive part. The upper midrange starts rolling-off and sometimes gives an impression of shoutiness, as if some sounds lost their intensity and are playing through a pillow. When I moved to my older jazz tunes that are extremely rich in the midrange section, it was clear to me that Zeus wasn’t soul grabbing to me, there wasn’t that meaty voluptuous sound that I’m in love with my Audeze and Kennerton headphones. It felt by a hair drier, but not to a point of calling them thin or lifeless, because Zeus are not like that at all. It has more of a linear type of midrange that leaves the rest of the spectrum shinning brighter, moving all the spotlights toward bass and treble areas. Nonetheless, I enjoyed my blues and jazz, acoustic music sounded good too, only sometimes I was missing a bolder and heavier tonality of high-end planars, but you can’t really have them all at this price point.

And DMS, well, He is sometimes difficult to read, because he'll not like a headphone's sound in the original review, then list it near the top of his Tier List.. It is always refreshing to review gear from Linsoul, as they are not pushy in any way, and I can take enough time to properly assess the sonic presentation and overall reliability of a product. This means that I got enough ear time with Zeus to both know perfectly how it sounds, and realise I may not have the proper linguistic skills to transfer that knowledge to you. Nevertheless I shall try my best. Despite a perfect marksmanship, I only had the Zeus for a few months, so I can’t guarantee how they’ll last for more, but I can say that Linsoul will always be there for you, and this headphone will always be comfortable. The overall tuning is just so good that by this point I will be adding the HarmonicDyne Zeus to Audiophile-Heaven’s Hall Of Fame, as a perfect headphone for their money.
