Unfortunately it is the little barbs in all such debates that tend to ruin any chance of having any meaningful discussion.
Thinking a little more about ncpl's comments above, I suspect that for > 99% of the time on HH, postings are generous, warm-hearted & welcoming. It is rare for comments to stray into 'barbed' territory & in my experience it only happens when the subject is one of 'marginal gains'.
eg: Meridian introduces an SE / XE version of their perennial DSP8000 flagship speaker, some forum members buy or otherwise get to hear the latest version and declare it to be wonderful. Result: No barbed comments. Elsewhere, somebody replaces his ageing G68 with a Trinnov & cheerfully announces that the improvement is wonderful. No barbed comments. On another forum perhaps, a member upgrades from a VW Golf (other cars are available) to a Lamborghini Huracan & declares the uplift in performance to be wonderful. No barbed comments. Someone on this forum suggests that Meridian is mistaken in placing little or no importance to the subject of mains cables and spends £X,000 satisfying their belief & attracts some barbed comments for their trouble. Elsewhere, our hapless driver announces that he is about to spend £X,000 on some bespoke car polish or some after-market HT leads & finds himself the subject of unwelcome derision.
Of course, to the outsider, pretty much everything we discuss on here is about marginal gains! But comments on here range from extremely generous at one end to perhaps 'barbed' at the other. Should we try to eradicate the barbed ones? Two people can read the same article about the benefits of mains cables / bespoke car polish; one finds any potential gains to be marginal at best (*snake oil*), the other reaches for his wallet. Personally I feel it is ok for those two wildly contrasting result to be reflected in postings on there. Others may well disagree.
