In a perfect world I could demo all of them and make a more educated decision. But if I was looking to go to high end, they would be my first choice. Not that UM or JH and other companies don't also have great products, it just seems when I see something from Wiz, it just blows me away. It does seem a tad like you are knocking me since I haven't actually heard them, which I do understand.
I am, but I am not pissed or anything :) I do believe, without having heard them, that these are high quality IEMs. And they are in my radar as I am investigated more "fun" iems to complement my Miracles and 1plus2 (which I haven't even received yet:) ).
However, I tend to react when people praise Heir all the time, because there is a huge fan wave right now, and it is a bit exaggerated. Do not mistake my thoughts: I think Heir Products much be great because many "serious" headfiers love them, but let us be more objective. Every time someone starts a thread asking which is the top CIEM to buy, Heir Audio says : "buy ours, they are the best". You could argue that other brands should do the same but it would be tiring. Besides, in these threads, many people claim Heir are the best without having compared them, and sometimes without having heard them. I own 2 UM CIEMS, but still I don't say they are the best on the planet. I think they are great, and I do not know how they measure to others. Some other brands I have tried the demos, but it would not be fair to compare demos and real customs. And again many people say: "I don't like this brand or that brand" just because they demoed a pair for 5 minutes.
Well anyways, maybe if I buy Heir 8.a I will haunt all the forums to say how great they are :)
