Stereophile Class A, etc.? Well...
The PSB Synchrony One (I have a pair; they're in storage) were listed by Stereophile in 2012 as a starred “Class A Loudspeaker Recommended Component,” along with speakers costing up to $80,000 in that category, and as a “Recommended Reference Component” by Soundstage Hi-Fi —again, in competition with vastly more expensive speakers. Summing up his review in Stereophile, founding editor John Atkinson wrote: “the Synchrony One offers surprisingly deep bass for a relatively small speaker; a neutral, uncolored midrange; smooth, grain-free highs; and superbly stable and accurate stereo imaging. It is also superbly finished and looks beautiful. Highly recommended. And when you consider the price [$4,500 a pair, and $5,500 a pair by the time they were listed as a “Class A Recommended Component"], very highly recommended.” SoundStage HiFi awarded the Synchrony One “Reviewer’s Choice” recognition when it was first released in 2008, then “Recommended Reference Component” status in 2012. The original review found the Synchrony One “among the most neutral speakers ever reviewed” that “sets a new standard for tonal accuracy, clarity and detail.” The follow-up review noted that the Synchrony One is “the least expensive speaker to ever be included in our list of Recommended Reference Components,” and that it measured (in the anechoic chamber of Canada’s National Research Council) lower levels of distortion “than any speaker at any price we’d measured up till then.” The review concludes “it’s important to realize that the Synchrony One isn’t being recognized as an RRC for the performance it offers at the price [$5,500 a pair]; rather, it’s a reference-caliber speaker that compares with top-class speakers at any price.”
Well...OK, boomers, boom me. But the Synchrony One doesn't. It's "soulless," as a friend put it. Doesn't do anything wrong, exactly. But it's just not engaging, exciting, "musical." My opinion? Yeah, but also that of several friends who have heard it in A/B/X comparisons with several others.
So why the rave reviews? Hmmm...
