I would never suggest there are no good modern A's. I haven't heard them all of course. But, most of the ones I have heard just don't appeal to me, and many just sound awful to my ears. I can say pretty much the same for many modern K's as well, although I do like some of the k Cons very much. My son and I have a 22" K Con medium thin high, a 22" medium thin low, and a 22" Light, any of which we could live with as a main ride if we had to. We also have a very nice pair of 14" K Con hats which are dark and jazzy, but still cut very well in a big band situation and also works well for pop and light rock and country. But generally, other than these we avoid modern Zildjians. If I'm going to buy new or "modern", it's usually Bosphorus (no surprise there) or AGOP. In fact my son's favorite left side ride when he gigs is a 20" Bosphorus Hammer with 2 rivets. Thin, dark, and trashy with a very woody stick sound and great definition.
This is what I am reading about them, and that intrigues me for sure. I mean, all I have known intimately is the A's that I have. Sort of like growing up in a small town where you don't know what's out there until you get off the couch and check it out!
I have a feeling I can find some sweet ones if I dig deep enough, but there are not 'piles' of them around the usual suspects to dig through- other than at Zildjian... This plan is looking better and better, but I'm sure I would be paying full boat to walk in and get cymbals there... On the other hand, they'd be the best of what they have to offer (to my ears) and therefore probably worth every damn penny. I'd only need hats, a ride and a couple crashes.
