I'm not knocking folks for wanting to save some money on purchases and for not wanting to always pay full MSRP for items that are available for a street price for less from authorized dealers. What I'm knocking is the mentality of folks who would abuse a dealer as a demo service with the full intention of buying elsewhere for the lowest possible price from audiogon or gray market or wherever they can get a lower price. That sort of mentality may get you a great deal now, but in a few years when you want another headphone you may be asking yourself "hey, where'd all the dealers go?".
Online doesn't offer much in the way of demo possibilities, at least not without added cost. Shops like Amazon aren't set up to allow many returns due to "I tried it, didn't like it". If you become a difficult or expensive customer at Amazon due to many returns or other issues you may find yourself banned from Amazon as a customer. Then where do you go? Would really suck to get banned from Amazon.
I don't want a future that's a sucky downward spiral to zero service style of market for audio. That's not a fun future for anyone who is an audio nut (and if you're wasting time here on head-fi you're an audio nut).
I never used DXC. It wasn't an online service I needed as I've got a local active head-fi network with local meets. I also had a neat local dealer at 32 Ohm Audio. Lots of headphones for demo there. But 32 Ohm Audio had to close up their retail shop. :( Cause well, probably too much of the behavior I mention above. Not a good picture of the future in audio retailing.
