Biggest obstacle for me wasn't WAF, I've been looking at speakers and reviews and forums for almost 2 years now, so she knew it was coming (once we finally got out from under 2 mortgages). And I think WAF is also covered as others have mentioned by the 30 day return policy with paid return shipping. I spent a good part of today with my wife doing a blind listening test between Cambridge Soundworks Tower II's (my old speakers), a pair of 6T's, and a pair of Axiom M80's. She pretty consistently preferred the 6T's the most. If she can notice a difference, it's an easier sell...
My biggest obstacle- is what do I compare? What brands? From where? How much does it cost? How do I get them? Most high end audio stores are well over 20 miles away one way, and most of them are custom installers with not much for inventory- and I'm close to St Paul, kind of, about 30 miles away. Point is it's not as easy to audition in stores any more, and I've seen more than a few people who live further out than I do from larger cities.
Places I did go to to audition didn't offer for me to take anything home, and Best Buy and Circuit City are useless to me for this. I need a center that fits a certain area. I want speakers that will look nice, not plain black or covered completely in black cloth. So that left me looking online for places where I could audition 21-30 days and return them with no restocking fee, and free shipping to me at least- I can handle paying return shipping for the convenience of listening in home. The problem is I can't afford to pay shipping for more than a few sets of speakers. So I ordered the 6T's, M80's, and was going to order a pair of Energy RC-70's that were on sale, however the sale ended the day before I went to place my order. I thought about Swan Diva's, but those speakers are heavy, and I would have had to pay shipping both ways. So I just did the two sets. It's still early, so if I come across a good deal somewhere with free shipping to me, I'll maybe try another pair. But as of right now I'm probably going to keep the 6T's. Which means I'll have to box up the M80's to return, in a box that barely made it to me no less, there is no way it's surviving a return trip...
Which brings me to my idea, which I'm not even sure how you would do it or how it would work. But what if you offered to pay return shipping for another company's speakers? If someone is looking to audition speakers and think they would prefer AV123 or Axiom, but they found out if they tried Aperion, which they could return on Aperion's dollar, that they could also return the Axioms or AV123s on Aperion's dollar- would they be more likely to try Aperions then? And are there people now who order Aperions and something else, and the speakers end up being very close performance wise, but they don't have a lot of money to spare so they return the Aperions because that's free to return whereas the others aren't? I'm not sure how often that happens, might not be much, but I bet it has (heck, I've thought about it, but I'm going to stick with the speakers I like best).
That's all I got for now...
