Hey everyone, we just received a very nice letter/review from one of our customers, Neil Wadhvana. He tried out the new Stella IEM for a few weeks and wrote this review:

Alright so here's my take on what I feel is an exciting new Light Harmonic product; the Stella. I was given the humble opportunity to audition one of the vew few pairs in existance as of now. Big shout out to Larry and the entire Light Harmonic crew; Thank you for letting me do this.

Stella Review:
Note: This is meant to be a standalone review of the Stella. Although it will mention other gear, it is written in a subjective, non-comparative light overall to help give some expectations, and choose pairings for the IEM

Gear:
Audio: Local FLAC, Spotify
Source: MBP 2016, Raspberry Pi 3
DAC/Amp: GO2PRO SEX, Chord Mojo
Cables: Stock, Generic Amazon Cable
Best pairing: MBP + GO2PRO SEX (FRM filter) + Generic Amazon Cable

Build:
In a single line, the Stella’s build is professional, sexy, yet slightly unrefined. Branding, serial numbering, color (god, this beautiful royal blue), and shape all appeal to me. The Stella looks edgy yet inviting and I think that’s an interesting combination of emotions to feel when looking at an IEM for the first time. The gold nozzle/stem on the model fits right at home with the gold plated mmcx connectors, and the LH logo looks right at home carved subtly into the body. The hexagonal design language carried into the cable and its junction/plug appeal to my appreciation for continuity.

The moment where the build starts to lose points from me is in the minute details; the seams in the casted chassis, the lack-luster mmcx cable connectors, the mis-toleranced wiggle between the nozzle/stem and the main housing, and the lack of proper adhesive on the wax filter. Most of these I believe are products of this being a test unit, and therefore I mention them only once in this review. The only usability concern I faced due to build quality was the slight itch I developed as one of the casting seams tickled the inside of my ear. I strongly believe this will (and really should) be fixed for the production run.

The case. This deserves its own, small paragraph. The Stella have been given to me in this modern, fold-and-rivetted leather case that I find to be absolutely gorgeous. I joked with one of the representatives that I would buy the Stella just so that I could have the case. It is soft; it can be debated whether it protects the IEM or not; yet I believe it deserves special mention for its sheer beauty. That is all.

Sound:
The Stella sparkles. My tastes in audio gear have usually been straight up reference-principled. I like things flat; without and additional magic. I find that with the Stella, I consistently expect a sparkling tonality to the music which I consume. Guitars sound ever so slightly brighter, snares rustle just a little bit longer when they ring, vocals sound just a little less edgy and microdetails in the high frequencies shine through. I catch myself constantly listening for the wisps of air passing through the singer’s nose, or the slipping of the guitarist’s fingers against the strings as they change chords. These details make recordings sound much more human, though this should not be confused with realism.

Now, this might be my reference roots showing, but I am a very strong believer that if something sounds good, it should sound good across the spectrum. The Stella have me re-imagining the level of clarity, shimmer, and sweet tonality that can be extracted from a recording. The way I pay attention to the piano, the way I emote when I hear a raspy voice, the way I listen for the air flowing through a saxophone; these are things I am used to working for when listening to my music every day. With the Stella, they shine through acoustic and vocal recordings effortlessly. For my personal tastes, this actually causes a bit of fatigue.

I know, I know, I said the f-word, however, I am extremely well versed with sitting with my eyes closed and listening with focus to hear these details and extract them. To have these same details thrust at me (albeit with beautifully executed precision and control) requires that my ears and mind to take short breaks to recalibrate to how the world around me truly sounds. This slight over-sampling feel to the sound is one of the few flaws I find with the Stella’s performance.

If we move now to traditional terms of qualitative measure for IEMs, I can say the Stella scales quite well (feed it with a suitable source and you won’t find yourself needing a $2000 DAC to appreciate the IEM). I do not find myself doing double takes at width/depth of the soundstage or crying at a mind-f**king V-shaped eq. Instruments are separated enough from the vocals that I can hear the difference in their respective distances and angular placements. Studio recordings are represented fairly well in terms of placement and positioning with a little extra longitudinal distance than I’m used to.

Mids are held back just enough to emphasize the sparkling quality of the highs. I don’t particularly miss any of the mid details or the specific textures in my tracks but just feel them pulled down as if someone put a few marbles on a parametric eq so they could focus on the highs where the Stella sings. All seems as I would expect from a TOTL IEM; All else except the bass. Listening to choral acapella’s and Classic Rock, I begin man-handling my DAC/Amp’s volume controls.

Knowing my tracks well, I pull focus from my work to prepare for a bridge, or a bass-heavy crescendo, and knock up the volume a few clicks to just barely hear the deep, rumbling tones. I wouldn’t go as far as describing the Stella as an all sparkle no kick IEM, but the thought has crossed my mind. This extremely strong bias of the IEM towards acoustic and string-accompanied music is the second performance aspect that rules the Stella out as a personal buy for my tastes.

And lastly, what I consider to be my most important genres for audio testing; EDM. Yes. EDM. Sadly, no matter how much I tried, I could not bear to listen to EDM on the Stella. The lack of lower power and overall balance makes complete albums sound tinny and badly-produced. Tracks that I consider required-passes for any gear purchase fail miserably in synth tonality, bass control/presentation, and survivability of the highs. The Stella simply aren’t made for EDM; they target acoustics, vocals, and strings.

Pairings:
DAC/Amp: The Stella has its own domain. It owns this domain and colors its sound shamelessly, aware that the user is expecting it to do exactly that. Trying desperately to pair this character with a DAC/Amp that has a character all on its own becomes a difficult task. In my possession, I currently have only a borrowed Chord Mojo, and an LH Labs GO2PRO SEX. The latter is a signature edition with further modifications and component upgrades done to only 4 units in existence (and I own SN: 0 of 3 😉).

It turns out that feeding the Stella from Mojo is actually a mistake as the two characters collide and interfere with each component’s strengths instead of compounding. However, feeding it with the GO2PRO, specifically in FRM Mode, makes the Stella sing. It stops having to bend to the DAC’s rules and starts showing its true beautiful colors, and I strongly believe this is how it should be.

Cable wise, I keep defaulting to the Amazon cable mostly for comfort. Outside of that, the stock cable to me did sounds slightly better, however, this is a completely biased opinion as I usually just stick to stock cables on most of my gear. The free flow of the Amazon cable makes the Stella much more comfortable for long term wear over the ears, whereas the Stock cable keeps me humble and aligns better with the Stella’s sonic character.

Closing note:
It should be noted once again that I am a devout reference gear lover. That being said, I go out of my way to swap off whatever I’m currently listening to with the Stella every time an acoustic or vocal track comes onto my shuffled queue. They are worth the extra effort for me on those tracks because I can get my gentle exposure and then swap them back out before I find myself cringing. If one of my classical music loving friends was to ask me for a TOTL IEM suggestion I would hands down offer up the Stella, and it will be a monumental feat for them to be dethroned in my humble experience with TOTL IEMs.

Cheers folks,
Neil Wadhvana

getting great feedback from our Revive.

First of all, since I've added the Revive in my circuit, I have roughly experienced a good 5% increase across the frequency range. I find the bass to be tighter and better defined. The mids and highs have tremendously improved, voices, especially female, feel more natural and clearer. To be honest, I don't regret purchasing the Revive one bit, it's a nice addition and now that I have tasted the fruit, I just can't take it out of my audio system. To me, that's a permanent part of it.
Love the fact there are 2 USB outputs
It makes a remarkable difference when connected!
Jon, D.
I have listened to it connected between my iPad Pro (also an iPhone 5) with the new USB 3 Camera adapter and my Pulse X Infinity using the Onkyo HF Player and Audeze-LCD-3 with Vero Reference Cable and Bass Dongle. Listening to some classical guitar I'd swear the sound is smoother and less digital sounding. Not sure of the right audio terminology, but in graphics terminology, it would be less jaggy. Glenn, E.

LightSpeed Ultra-wide Bandwidth USB Cable

LightSpeed USB uses a unique topology, which we call Ultra-high Speed Differential Pair (or USDP). USDP gives LightSpeed 20 times the bandwidth of USB 2.0 high speed, which ensures optimal signal clocking. In fact, LightSpeed’s astounding 10 Gigabits per second bandwidth is twice as fast as USB 3.0! Additionally, its 2-in-1 architecture physically separates the signal leg from the five volt power leg, preventing source-generated noise from disturbing the digital signal. The result: a bit-perfect USB cable.
