Until last few months, Hiby products were not available through resellers in France, neither in Europe, and even the Hi-Fi shop in town has Mainly Fiio at display.Your last statement is the problem, when you live in a country like Canada where only 10% of the products are available here, try before you buy isn't an option. The only DAP I might be able to try locally is the M5 Ultra once it arrives and most headphones aren't available here either. Even amazon.ca hardly carries any DAP's I can order to try out.
In most cases the audible differences between DAP's in the same price range are to minor to worry about. What I am looking for most in a review are any glaring issues that make it a bad option for me or a bad match for my headphones. When the reviewer said the mid-bass sounds hollow I take note of that and see if this opinion is shared by others.
So out of Fiio's most sold DAPs, you're forced to buy online (either EU or CN), or find it on the used market... More or less the same than in CA.
I never expect any SQ issues from a DAP, but I am more concerned by a poor battery life, poor wifi range, sluggish interface... Where the reviews are of great use before buying
