I am late to this discussion as I wasn't aware of it until today or I would have joined it much earlier. I may be wrong but I think Teejay is an audiophile first and a critic second. As an audiophile he enjoys sharing his insights on gear that punches well above it's price point. As a critic, he has access to a lot more equipment then most of us do. He was spot on with the Tekton Design speakers so when he raves about something ; I listen.
As for retailers joining discussions, I have no problem with them contributing as long as they state that they sell audio gear and if a discussion is about a product they sell, they should inform us. I have seen numerous very informative postings by retailers and look forward to reading more in the future.
