Once upon a time I had the Atlas...absolutely loved it and had my eyes on either the Andromeda or the Solaris as a complement, with the Atlas staying on board as my main daily. I'd read reports that the Solaris lacked bass or that its bass lacked impact so I had the impression that its bass wouldn't be sufficient for the Solaris to satisfy me as my main or only IEM. One day a couple months ago I had the opportunity to a-b-c the Atlas, Solaris and Andromeda for over an hour. Long story short-- the Solaris totally blew me away in all respects, imho combining the best aspects of both the Atlas and the Andromeda, and I wound up buying it, selling my Atlas, and I haven't looked back since. The most common complaints about Solaris (fit issues notwithstanding) are that it lacks bass or is hollow sounding in some areas-- both of these issues only crop up for me when I use the wrong tips or am unable to get a good seal, so I can only conclude that the people who make those complaints didn't use the right tips or stick with it long enough to get a proper fit and seal. With the right tips and a good seal the Solaris' bass is tight, powerful, impactful, deep and punchy. It's not as intense as the Atlas across the board-- in recordings without bass you won't hear a lot of bass, but where bass is called for it absolutely pounds and adds a good helping of Andromeda-like loveliness dovetailed throughout. Since you live in the US my advice to you would be to grab the Solaris direct from CA, demo it, and take advantage of their return policy if you're not satisfied. I'm pretty sure you'll be pleasantly surprised-- the Solaris has totally changed the game for me. Its impeccably balanced, solid through the whole spectrum and the quality of its signature only becomes more and more apparent the more you listen to it.
