Yeh that sucks and is extremely unfair but sounds like it's common in many European countriesIn Switzerland there are shops for 2-channel that are willing to work with you, but for high end headphone gear there is really just one store, they are super helpful, but most gear they do not have in stock (like AB-1266) so no way of even testing it at home. Some other things they do have and are willing to help you out, but even then there are limits in what they can do. No way of buying let's say Formula S, having it for a month and then deciding. As far as returns go, that's not very common here (except for one shop that sells electronics, but they don't have high end audio gear) and even there you get hit with 10% restock fee. I have managed to convince some shops when I bought something and wanted to upgrade for something else (more expensive), they worked with me and gave me a decent price (so did not need to sell first). Some equipment you can audition at the dealer, and during Pandemic they were willing to lend you stuff for a week, but again, not as liquid market as in the states or in the uk, what a pity.
