Have you considered sending a pair to smaller music instrument stores in the cities to have them as demos and then listing available locations on your website where people can listen to them?

No matter the reviews I think buyers will always end up getting something they can actually hear. It's very hard to commit to buying something unheard, it's basically asking for a leap of faith. Because if you don't like it and want to return you either have to swallow shipping costs or pass them onto the seller, and probably, ultimately the manufacturer (you) which for some may feel not a right thing to do. It's an expensive way to "try something out". For somebody, most likely your company (unless you split shipping costs with the dealer)

I almost ordered IN8 a few months ago when I was looking for my monitors replacement, but ultimately decided to go with other because I just couldn't find a pair of IN8 to listen to and didn't want to risk having to go through returns and pro reviews at the time were non-existent (there are still only 2 that I found, from audioscience and mixonline, which I read the other day and are in fact positive).
