I got my money back without a problem.
Gina contacted me to tell me that my Wave 32 will not be produced and suggested me a 100$ upgrade to Wave 64 with many "free" extras. As I am not interested in a DAP anymore and thus don't want to spend more money on that, I asked her to cancel my Wave 32 order completely. I got my money back on the same day through paypal.
Gina replied very fast and kind to my emails.
The next order I want to cancel now is this damn Verb IEM, don't know why on earth I ordered that. However I am afraid that won't be possible as the Verb is still produced. I guess that refunds are only possible for products that are not being produced by them anymore, thus if you refuse to upgrade, what else can they do than refund the money back?
