      Music lovers come in all stripes and colors. As much as I love the multi box room dominating rack of separates which make up my reference audio system, that kind of space and financial commitment isn't realistic for, or desired by everyone.

OK. Given a world-wide pandemic, why are we reading (and writing) audio reviews? First, as Congreve pointed out, "musick hath charms to sooth a savage breast."
