Nectar Sound was kind enough to send in the Ambrosia for me to take a look at (and listen). They’re known for the HiveX estat but this one is a dynamic driver headphone using what appears to be the same driver as what’s in the Aurorus Audio Borealis, which is another headphone that’s gotten recognition in a number of communities. So think low impedance 50mm.
The Ambrosia sells for $499 on their site linked above.
Here’s the Nectar Ambrosia frequency response:
GRAS (vs Harman):
The stated goals are to achieve a sound that’s mostly neutral just with extra body, and I think that’s kind of what you get here. It’s noticeably relaxed in the upper mids and treble, meaning perceptually the emphasis swings a bit to the lower frequencies. I’d describe the sound signature here as competent and ‘pleasantly relaxed’, even though there are definitely some quirks throughout the ear gain.
There’s a bit of a forward character to the mids and lower frequencies and I’d say it’s reasonably capable down low in general, and treble also sounds sufficiently balanced to my ear on this one without any major fatiguing quality to note.
At the same time, there’s also nothing really that jumps out at me as far as subjective qualities, and if anything I’d say its a bit smoothed over for small gradations of volume and finer little nuances in the music. So it’s less about grabbing your attention with all the details and more about that relaxed presentation.
It’s also very comfortable for me, however the build is certainly on the ‘DIY’ side of things, so I wouldn’t expect a super refined feel and finish.
My general sentiment towards this headphone is that it’s another take or interpretation of this driver that’s similar in some respects to what you get with the Borealis, and it’s cool to see some of these projects get off the ground.
I’m curious to try experimenting with this driver myself as I think it’s a decent platform to start developing headphones on, even if there can also always be improvements. I’d love to see what Nectar can do with something a bit more high end as well. But this is a decent first effort with a DD that may appeal to those looking for a more relaxed presentation.
