Why do all audio forums on the internet seem "dead" ?

Yamaha and Denon stuff with Monster Studio links....the Denon CD player wasn't half bad but the overall sound wasn't even close.  But that's me....most musicians don't own or care for stereo systems.  Enjoy what you does it for you....some like redheads and others prefer blondes.  I'm a brunette guy....they all have the same parts, they just perform differently under certain dynamic conditions:)

I think one major reason that audio forums seem slow is Facebook - where people at least ostensibly have to post using their real names. That tends to make for a better signal to noise ratio. Contributors are a lot less likely to be snarky or pompous when readers actually know who they are.

I think the forums are useless - that is why.

They are inhabited by those trumping their own latest high priced expenditures (to justify things in their own mind more than anything else). They are further fuelled into aimless merry-go-round equipment changes by the clever "fear and bogus science" marketing of savvy dealers, sellers and boutiques (you know who you are).

There are some here who genuinely appreciate music and have good ears but they are drowned out by tin foil hatters and all manner of special unproven but "fantastic" tweaks (the grossly expensive speaker and interconnect cables being a clear example of the ridiculousness of these forums when a decent XLR or ordinary cable will do)

I deliberately left these forums for several years and just came back to check and see if anything had changed - it hasn't - forums are still stuck in aimless rambling, hyperbole and anecdotes as they were 10 years ago when I first joined.

I got better things to do! So long and thanks for the fish!

Well, if you speak of Audiogon, those of us who have been around for a number of years, know that Audiogon shot themself in the foot a few years back. Although this site now appears ’slicker’, it just ain’t the same. Too much of this site’s sale’s ads are from dealers. This is a much larger percentage than prior to Audiogon’s changing ownership. It is sad, as it does seem that the ability to sell a good item, has decreased markedly since 2011.

In addition, I am not sure what 'you' mean by Classic equipment, but there is not lack of it out there.  The problem, now, is that it's quality is acknowledged, and the prices reflect that.  I was having my tube amp repaired, and I was at my 'repair guy's' place last week.  He purchases, and refurbishes classic McIntosh tube gear.  By the looks of things at his place, he may have cornered the market of Classic Mc equipment. ;)
