Would I consider buying $10,000 speakers (or other) from an online company?
I think there are several things that I would need to take into account.
I don't think first is the brand name or necessarily their reputation. But, I think most important would be in-nation support. I read FAR too much information about people who buy product from overseas, then are shocked when they have to ship it back to the originating country, on their own dime, when it has an issue. I think this is especially the case for speakers, and moreso for active speakers.
Where would I need to send them if I had an issue? If I didn't like them in my setup, where would they need to be returned to, and would that return expense be out of my pocket?
I would say that the second thing would be that I would expect a reasonable return policy on the product. If I can't audition them in person, then I need to audition them in my home. If they aren't to my satisfaction, then I certainly don't want to be stuck with them in my home forever. My intent would be to treat the product fairly, but I also expect a balance.
From there, the third thing would be the reputation of the company itself. If they are known for high quality parts and products, then that would pretty much make it tough direction to go. I mean, if the first and second criteria is met, then I want to ensure that I'm dealing with a fair and honest company. If there are complaints of product failures, or of bad build quality, then obviously I'm not buying anything. But, if the company is well regarded, which it sounds like is the case, then it helps to make up my mind.
I think this is a tough one for a non-US based company that doesn't have a footprint in the USA at all. I'm not sure how much product is sold in the USA, or how much demand there would be, but that's likely where my direction would be first. To establish a foothold for a service partner in the USA, and a store/showroom that could support my overseas product in the USA. Even if it's a limited store with only a few locations. Just having a place where residents could return a product to without it being international shipping would be a huge plus. It may offer some the ability to hear them in person as well, which is great for them, but it allows for in-country service and returns which is absolutely huge.
