Well, I guess I'll know soon enough. The things is that just like the VSD1 Limited Edition isn't going to be my first vsonic iem, so the Delta won't be my first Brainwavz iem. And somehow it's easier to believe that a limited VSD1 version exists that sounds better than all the other sub-$100 vsonic iems because the standard VSD1/S is already up there in performance than to believe that Brainwavz just made a $20-iem that suddenly sounds better than every single sub-$100 iem they've made before.
Anyway, I'm not the type who bases his opinion on assumptions or other people's opinions and that's why I also have the Deltas on their way to me. Of course, I wouldn't mind if the Delta turns out to be a great performer - all I'm saying is that I don't have unrealistically high hopes about it just because a few people said it's on VSD1's level and even better but I'm always happy to be proven wrong and if that's the case I'll be really hyping these Deltas. For now, I just sit and wait.
