We are buying and reviewing gear all wrong

So let's assume that cables, power conditioners and electronics all contribute noticeably to the sounds we hear.

In that case, maybe the idea of buying individual gear, reviewing individual gear, etc. is all messed up.
We should review entire systems, and buy entire systems.

This idea that we constantly shuffle interconnects, speaker and power cords for all our lives is messed up.

We shouldn't be looking at audio stores or reviewers as recommending gear, but themes. Styles. Entire collections all at once.
