I have had the Solaris for a couple of weeks now. The sound is super dynamic and the soundstage can deliver a holographic feel. I am impressed with the build quality, but I am not surprised as the build is always great with Campfire Audio gear.
I am pasting some thoughts I have posted on another forum:
“So far, I am enjoying the Solaris. The fit is fine for me, especially if I am standing and walking if I am laying, on my back, I fidget with them a bit to maintain the seal. The Spiral Dots L are the best sounding tips I have for the Solaris, I even peeled a Mandarin. I am impressed with the ease at which the Solaris can be driven, I learned the hard way about volume. So far, I have been utilizing a Samsung S10+ and plan on critical listening with DAPs over the weekend. I was listening to Ezra Collective, You Can’t Steal My Joy, this morning and all frequencies were represented clearly and on point. The overall signature is full and expansive.
The stage doesn’t appear to have defined edges, such as a square or rectangle, it expands wide and tall. Occasionally sounds appear at an odd point, for example, as if it is coming from the left side above my skull. Nice holographic feel. The treble has a bite and extends well. The treble takes you to the edge of harsh at times but never goes all of the way there. I am treble sensitive, but I find the treble close to perfect in its extension and level. I have found the Final E tips control the treble a touch more than the Spiral Dots, but I think it is mostly due to the bore size. The Final tips would be my overall second choice. My custom tips sound and seal great, but they cause the IEM to resemble that JH Audio Frankenstein bolt look and stick too far out of my ears. The sub-bass thump and bass throughout are less the Atlas but the bass is very controlled more so than the Atlas, but I currently have so many hours on the Atlas that it is now completely different(for the better) from the initial hours of listening. The bass is very dynamic and lively with a natural tone and texture. Overall the sound is clear, vivid and quick. The bass is not forgotten as it is in many clear and dynamic IEM’s. My experience, thus far, has been positive”
