Impressive, this thread has 36 pages of content! I can understand how a thread that started as a discussion about reviewers could migrate to discussing resellers. We are ALL part of the hobby/business, and no doubt, sometimes interests align, and sometimes not so much.
Bonzo is spot on; some businesses specialize in selling pre-owned and distressed gear. Wilson wisely set up their prime dealers as resale points for their earlier generation speakers (and God knows they have many) to better control their brand and customer experience. Rolex did the same.
In my view, you get what you pay for. Some buy discontinued products, closeouts, and used gear for value or simply as an affordable way into the hobby, and there is nothing wrong with that! The same is true of used luxury cars and Swiss watches. The internet has seen dealers rewarded by going out of their way to ensure the pre-owned products they sell are accurately presented. Many pre-owned buyers I have dealt with have the same and, in some cases, higher expectations than new buyers. In short, it's not a walk in the park to squeeze a 10-15% margin on used gear, and like Elliot, as my business has grown, I do my best to stay in my lane, representing and supporting my lines only.
A vibrant pre-owned market helps professionals like Elliot and me and enables consumers by creating a hassle-free opportunity to trade in and trade up. Many new high-end sellers will over-allow trade-ins toward new gear to help the buyer get into the gear he wants to own. It sounds like a win-win to me.
Concerning reviewers of all types (as many of you have expressed), if one uses those reviews as entertainment and information, then what's the point of debating motives we will never fully understand?
It's a great hobby for everyone, whether professional or amateur. Here's to getting back to it!
