My gripe is that the Zeus and the A12 have got that new ADEL stuff going for them, but I'm still undecided on that tech adding another layer of premium. I followed AAW products because I'm a bit of a bass head, transitioning from full sized cans to my IEMs now (Empire Ear Spartans and the Shure 535 LTDs), I really miss that slam and authority from the lower ends. It seems that the dynamic driver and hybrid integration would suit my tastes nicely. I wouldn't want to go in blind either, but with AAW based in Singapore and their only participation in Can Jam being the Can Jam in Singapore (and I am in So Cal), I don't really know where I can go to get a personal impression. I briefly considered picking up a pair of used W500's somebody has for sale here in the trade forums, just to consider the sound signature and the difference of that dynamic driver versus the all BA stuff I'm currently using, but if I end up hating them, it'd be hard to resell a CIEM and if I ended up liking them, I would still sell them to foot the bill for my eventual W900 anyways. With all the fancy claims and hype that has been going on surrounding the ADEL tech, I was going to hold off on my TOTL CIEM purchase until I could get an impression at Can Jam So Cal in April, but I'm pretty sure this deal would be long gone by then, right?
