I don’t have a problem with posts by dealers in general or Dave Lalin in particular. If I go into a dealer’s store I expect him to try to sell me the gear he sells.
Except this isn’t his store you’re walking into, it’s a forum for people to share their advice and opinions. As stated before, several other dealers/manufacturers post here without issue because they provide information and, unlike audiotroy, don’t promote their products as being better than others or claiming the other recommendations made members here are inferior to the product he sells. THAT’S the problem and what other vendors here DO NOT do. See the difference?
