I am currently testing the CCA CS16 (8BA) and it is very promising.
Looking forward to your feedback on these, particularly since there is little else to go on at the moment.
I am all over modified (wide nozzles) ASX for more than a month now.
With the wide nozzles everything opens up, ASX are still a bit of bass-head IEMs for me, but they do have everything to enjoy the music.
Having a hard time getting around to modifying my ASF. Heavy work load and spotty sleeping pattern, lately. Looking forward to eventually modding mine to be able to offer additional feedback
and to enjoy them, of course.
hehe
I wanted to buy another pair for my collection and I've been considering two.
The choices are BA10 and AS12.
My recommendation would be to start with the BA10 and pick up the AS12 shortly thereafter.
There is more feedback on the BA10 and much of it is very positive. In addition, they are, likely, out of production. This means that once the current stock dries up the BA10 will be very difficult to obtain.
The AS12 could very likely be out of production as well but you'll probably have more time to acquire a set since they are only now being reconsidered.
The AS12 (2019 release) is now going through the same two year cycle that the BA10 (2018 release) went through. The BA10 was overlooked by many for innumerable reasons but it is now being recognized for what it's been from day one, a great all-BA set at a bargain basement price. In the coming months I expect history to repeat itself with the AS12. As more feedback comes in the current stock will be depleted until it's gone.
In the meantime, be aware that the AS12 and BA10 sound completely different. Their presentations are not even close to sounding the same. That being said, they are both excellent in-ears at unapologetic but nevertheless affordable prices.
Lastly, both deserve upgrade cables. You can pass on the upgrade cable until you determine how well the BA10 or AS12 fits you but once you know it fits you'll definitely want a better cable, without question.
If AS10 warmth is to be build upon with great bass and good mids - AS12 will work nicely; the BA bass is the best out there! (and I do have some Knowles and Sonions to compare).
The BA10 shells are very nicely built, a real masterpiece (minus the fit considerations).
(I can only agree that AS12 are better than AS16, if treble is not much of a factor. AS12 do feature very potent treble BAs but they are heavily dampened, so are the higher overtones. Undampened, AS12 are a treble beast; customization of dampening offers great opportunities, in my opinion).
The AS12 treble modification is another modding project on my to do list (Tin T1-cable, KB06-resolder, ZS1/ZS2-nozzles & crossovers if possible, ASF-nozzles/filters, AS12-nozzles/filters & DQ6-nozzles. I also have a handful of old skool fixed-cable KZ's that I'd like to recable with better 8 core cables).
Typically, when I have an hour or two I just want to veg out and enjoy my music but I'll get to modding, at some point.
