I'm struck by how often people caution great care when advising others about upgrading, which I am sure is sound advice (NPI) - often it's suggested that X might not work with Y, or with the room size etc. I am not questioning the soundness of such advice, but I can't say I've ever regretted upgrading and very little of what I have bought has been demoed at home - several bits were solely off the backs of reviews or sourced from eBay. So, have I been lucky? Have you bought stuff that you have regretted*?
