I’ve been reading audio forums for years and they have always had their share of posters that can’t seem to allow others to take pleasure in their purchases.
As an example someone might post how they have purchased a new cable and are very pleased with the improvement it has brought to their system. The negative poster will reply stating that there can’t possibly be a change in sound quality from changing this cable and the purchaser must be fooling themselves.
Recently the number of ‘disbelievers’ seems to be on the increase. They don’t believe that different cables sound different, that different supports sound different and even seem to believe that digital is digital and if it doesn’t have errors it must sound the same.
I tend to think the safer way is to consider that every change you make to a hi-fi system is audible. Might make it better, might make it worse or it might be so small a change it doesn’t really matter, but there will be a change.
In fact if you make a change and you can’t hear a difference then consider why.
Is it a scientific way to look at things? Probably more so than trying to convince yourself there isn’t a change.
