I do feel it is an acquired taste. About a week ago I received my Darkvoice at the office. I got a lot of puzzles looks, and people that were curious but didn't ask. I also got two people really interested. One of them is very curious about technical stuff, and didn't have the chance to attend college. But he was way open to listening to my explanations. He was also curious enough to try, and he told me before hand that he wasn't into sophisticated stuff, that he wouldn't be able to tell the difference. I told him to try and he told me he didn't notice a difference between the Darkvoice and the Corda Move. To be honest, I hadn't AB them yet, he was the first one to try because he was eager to figure out why I had bought that kind of stuff. I did one simple thing for him to experiment. I told him to close his eyes and try to imagine teh soundtage and he did. I played for him "Got my mojo workin'" from the Mojo album by Big Joe Maher (Mapleshade), and he did close his eyes and relaxed to it. He was marveled at the positioning and clarity. We then changed to teh Darkvoice, and he was smiling. he told me that it felt better in some way he could not describe, as if the music had more presence.. more strength to each element and as if the room were bigger. I was amazed by his description.
As opposed, I had guys that usually listen to music on sony ear buds that started up by attacking my choices without listening to the gear. Without losing themselves in the music first.
So I believe that several factors are at work here. The first question for such individuals is "How long has it been since you don't really just listen to music?". I've found most people just use music ans background noise and don't have listening sessions in their lives. It's been years since they don't listen to music and do only that.
The second factor is an open mind. If your audience is not willing to understand that there are other hobbies out there then there can be no common talk. As many have said here we all have to learn to respect other peoples hobbies, and we also have all to learn to try an understand how deep stuff can go.
