...And though Ken Ball's unintentional deviousness to make perfectly complementing IEM's with the Andromeda and the Vega does make me want to only buy the Andromeda next, I have not had the thought of getting or searching for new IEM's. Now, there is a financial reason to that, too, but it only crosses my mind when wise alec's like @thatonenoob write compellingly valid sense to do so.
I have seen other threads where people buy several entry level/mid tier products that they almost know aren't going to reach a point they are searching for, yet are empirically ignorant of, that CA IEM's provide in one package and more generally so with the TOTL models.
It's really hard to believe how new the CA lineup is.
The Andro and Vega are very complementary tunings, and work wonderfully well as two sides to the same sonic coin - stuff that doesn't necessarily play to the strengths of one IEM will almost certainly be bang in the middle of the other unit's comfort zone.
That being said, both share similarities in terms of the tuning approach, so if you aren't a fan of the Andro, you aren't guaranteed to like the Vega, and vice versa. Fans of a more technical or clinical sound may prefer other flagships, but for fans of a musical approach to presenting sound, I will admit that the CA line is very hard to beat for pure enjoyment. I'm trying to write up some comparisons on my Zeus-XR and the Andromeda at the moment (still need to get the Andro review written at some point too) and both are mind blowingly good but very different in approach, and despite the difference in price, it usually comes down to my overall mood and what I want to hear as to which IEM I feel like listening to.
