I’ve commented on this combination so often—five of these eight brands occupy my music room—that I didn’t linger long in Quintessence Audio’s excellently assembled “Knowledge” room. That didn’t stop me from admiring the contrast between the riveting yellow finish of Wilson Audio’s Chronosonic XVX loudspeakers ($387,000/pair) and the bold black-and-copper livery of Dan D’Agostino Master Audio Systems’ Relentless M800 monoblocks ($195,500/pair). I began to wonder if the lovely blue of my Wilson Alexia Vs is a bit too sedate. When I chose my speakers’ finish I almost opted for the perfect shade of orange—bolder, like the XVX’s yellow—and now I wonder what the past few years might have sounded like had I gone that route.
