LATEST ADDITIONS

Sometimes I wonder what the etiquette is at audio shows. I mean, nobody tells you anything. It’s fair to assume that playing windmill-style air guitar to songs by the Who is generally frowned upon, at least in public, but is it gauche to sway and groove in your chair when the music moves you?

Jorge Sadurni, whose impressive horn speakers I first encountered at AXPONA during its pre-Schaumberg years, introduced his Spherical Dual loudspeakers ($4600/pair with integrated stands—see driver in the photo.) Each Spherical Dual contains two high-damped cast-metal modules with 5" cone dynamic drivers.

It may be strange to read what I'm about to say in the pages of Stereophile, but it's the cold hard truth so here goes: Audio reviews are inadequate. They don't tell the whole story. They come up short and can even misdirect.

It's not their fault, or at least sometimes it isn't. Even the good ones can't tell you how something will sound to you—let alone make you feel, the ultimate point—in your own room. As helpful as they may be, they can't address the elephant in the listening room: synergy.

In reviewing the Octave Audio V 70 Class A integrated amplifier ($12,000 and up; $15,900 as reviewed), I was reminded of the importance of synergy in our hobby.

One question the Stereophile team asks in every AXPONA room we cover is, “Is any of the gear new?” The Cambridge Audio team wins a trophy this year—or would if there was a trophy. When I dropped in for a listen on the first day of the show, account manager Joseph Buechel told me that the Class AB CXA81 MkII integrated amplifier ($1199) was making its debut "today, right now."

Damon Von Schweikert, CEO of speaker manufacturer Von Schweikert Audio, did something interesting in the room (1621) he shared with Gary Leeds of WestminsterLab. Faced with a challenging room whose opening to a second inner chamber of similar size all but guaranteed that bass would be a mess, set up two Von Schweikert V-12XS MkII Shockwave subwoofers ($33,000 for two), facing each other.

Another big system with a midrange to love, with speakers well-matched to the space. I wasn't converted to the style of singer Vanessa Fernandez, whose cut from her new platter seemed more derivative than inspired, but the midrange sounded excellent, and there was also lots of bass to attract attention.

Review samples of some new high-end audio products do not grow on trees. They are more like dray horses trouping from one destination to another. After the US premiere of the Technical Audio Devices (TAD) Grand Evolution One (TAD-GE1), a floorstanding speaker from TAD's Evolution series, at the 2023 Capital Audio Fest, the review pair came to stay with me in Upstate New York for a couple of months before traveling on to the 2024 Florida Audio Expo for another public appearance. After that, they returned to John Atkinson for measuring—then off again on another journey.

The TAD Labs GE1 is a three-way, three-driver design. Up top is TAD's proprietary Coherent Source Transducer (CST), a 5½" coaxial tweeter/midrange driver. Two matched 7" woofers fill out the middle of the front panel.
