SF is a great conventional dynamic speaker with low end up to nice high end models. Mac stuff is a bit pricier but wonderful and can cover all bases. They are a solid pairing in my estimation, like that of other prior posters.
Some others seem to have trouble understanding a great ‘what
if’ question that asked very simply for an electronics mfr/brand (not an entire
corporate structure) and a speaker mfr/brand. And rather than
moan and complain about the question, why not leave and move on to another topic...
