As long as manufacturers, sellers and others with commercial audio interests sail under their own flags, openly - and dont post to the detriment of others - I am OK with it.
I also have quite good experience with my Synergistic Research A/C Master Coupler X2 cables. There, my interests ends. No commercial or user affiliation.
Of course, a manufacturer or seller will be influenced by the product s/he makes or sells. Happens to all of us. We have the tendency to defend the gear we bought. Sounds like the best in the world.
But the purpose of Audiogon, the way I see it, is to invite all this variation, into healthy debate. Saving us all from doing everything on our own, helping us to become more critical listeners and experienced customers, avoiding bad deals and adjusting what we have.
I appreciate the posts from mahgister, basically saying you can treat your room for low cost, rather than invest in component upgrades. I wonder what can be done in a combined living / listening room, like mine.
I asked - how can we search better, on the web, for good user experience beyond semi-commercial information. Thanks to ricthetrick for comment. But not answered, so far.
