You seem locked into this "old vs new" paradigm:
You know, an audio system is composed of more than one piece of equipment. Even if someone has, for example, a vintage receiver, that doesn't automatically mean that they are listening to Vinyl, or even that they are powering vintage speakers. The need some people have, to make the forced distinction between "new" and "old", is what I consider to be part of the problem. What I see on this site is not people who cling to old gear, but rather people who evaluate each piece of gear based on it's own merits, regardless of age or other irrelevant forced categorization.
If you're implying that there is backlash here when people recommend new gear, I'm just not seeing it. When someone asks for a recommendation about JBL speakers for example, the #1 recommended speaker is usually the
JBL 590, which is certainly not a vintage speaker. I received a lot of help here when I decided to add subwoofers to my system using kits from partsexpress, again completely unrelated to vintage. And it was this site that first turned me on to the
miniDSP which has improved my system tremendously.
