we are making something fairly simple unnecessarily hard
the idea of this forum, attached to the main a-gon buy/sell/advertise site, is to have a community of primarily enthusiast/audiophile consumers, who, in addition to trading their gear, also be able to exchange ideas and experiences
of course, then, there are also manufacturers, dealers, and others within the high end hifi industry, who come here to access these consumers, to sell them things, and as other posters here have rightfully said, these additional people bring a lot of knowledge to the table, and can/should contribute their insights
so it seems simple, and reasonable, that when an industry person ’expresses their opinion’, they should also let folks know who they are, above and beyond being just an ordinary user/enthusiast sharing their personal experiences -- that they have an economic stake if others here ’act’ on their advice
so someone saying "your gear will sound better if you use a specialty fuse"... should then say "oh btw, i sell them".... or ... "vandersteens will be great in that room to play the classical music you listen to, and oh btw, i sell them" ... or even... "hey i think the nad m33 is a great integrated amp, so many useful features, sounds just great, and oh btw, i have mine listed in the for sale section...."
done right, it’s really not so hard... but i believe there are many folks here who will not, do not do this
