This discussion is good, I reckon. I've added, to the Posting Guidelines:
Please DON'T be rude to people and start arguments on the forums over this, however. If you must, point them to the Posting Guidelines. I wrote them up in the hope of setting a high(er) standard here, so I'd hope everyone reads them. It's important the focus remain on positive contribution, not warnings and rules. I hope that more people will post product reviews and add pictures, for example.
What I've done myself is made posts with qualifiers, which I think is reasonable, eg: "I own product X, so if their new product Y is anything like X, it should be promising." When someone posts a thread asking a question that I've been pondering as well, I might post "I've seen lots of positive comments about Z for this and am interested too." The furthest I've stretched this is, being familiar with the thoughts of other members who own the same gear I do, I can say "N had good things to say about X and since he has similar tastes to me, it is something I'd consider in your position." When I say these things, there are a great deal of other factors I take into account, however, which may not be obvious.
Priorities, in my mind, should always be:
A person's music tastes.
How loud they listen.
How they intend to use it.
Getting to a meet or shop where they can try first.
