I agree completely that speakers have to be matched to gear, but why do so many dealers not do that? I listened to the 804 d4’s powered by all Mac gear and the first song they played was Lorde’s big hit from a few years ago and I knew immediately I didn’t like the high end. After about 15 minutes, I asked them how long they had this setup expecting them to say it was new and needed some break in, but no, that was not the case.
