LATEST ADDITIONS

On the Renaissance hotel's 16th floor, in the room occupied by PureAudioProject, folks were utterly baffled. Also, occasionally horny.

Apologies. The fact that I'm away from home for four, five days to cover AXPONA means I temporarily don't have my teenage offspring to mortify with dad humor, so now I'm inflicting it on you. PureAudioProject, you see, makes open-baffle speakers. Some have horns. There's a reason I write for Stereophile, not Saturday Night Live.

At AXPONA 2023, Luxman America's Jeff Sigmund and John Pravel brought serious sonic finery from Luxman Japan with the same gracious, enthusiastic, generous manner they've extended for years.

I'm an unabashed Audio Note fanboy. You got a problem with that? Audio Note lives deep in not only my sonic soul (an Audio Note M2 Pre was my first serious hi-fi purchase), but those of colleagues Herbert Reichert and Michael Trei, Audio Note distributors back in the 1990s, when tubes were cheap and the only thing Upscale Audio's Kevin Deal sold!

Audio Note returned to AXPONA with nothing to new to spring on the hungry (really) crowds, only the same consistency of sound major domo Peter Qvortrup has offered for decades.

If you're like me and the topic turns to active speakers, you'll probably think of affordable products. Maybe the mighty $649 Vanatoo Transparent One Encore comes to mind, or the sub-$1000 powerhouse that is a pair of SVS Prime Pro wireless speakers. The KEF LS50W is a strong contender even at $2800, and if your budget allows, you might consider Buchardt A5s ($3900/pair).

Two months ago, at the audio expo in Tampa, I stumbled upon a pair of most intriguing French speakers. The $8000/pair Diptyque 107 is a medium-sized planar magnetic whose designers, Gilles Douziech and Eric Poix, make no secret of their love for Magnepan. All the same, the duo has sought to improve on that company's famed panel technology, mostly by addressing a perennial shortcoming of such dipoles: their lack of deep bass.

I wasn't necessarily expecting to find Alon Wolf (right) striking dangling bars of aluminum with a small mallet. Had Magico's celebrated designer embarked on a second career as a percussionist? Nah. He was demonstrating to Stereophile Editor Jim Austin (left) and myself that aluminum, which Magico has long used as the ideal material for its enclosures, rings, but can also be very effectively dampened by sandwiching a proprietary elastomer between two layers of it. The first (untreated) bar rang like a bell. The second one had a padded adhesive backing that took away about 80% of the effect. The last bar was the aforementioned sandwich, and yup: dead. No ringing.

As audiophiles, we strive almost obsessively for a low noise floor and no distractions, only to be spectacularly thwarted when we evaluate equipment in a retail or show environment. Around us, people are entering and exiting, and often talking up a storm. The air conditioner is set to a low drone. Bass notes leak in from the next room over. AXPONA's cavernous Ear Gear space, where more than two dozen manufacturers of headphones and related equipment were demonstrating their wares, was awash with buzzing, excited people—the best kind of noise, really, even if you have to turn the demo cans way up to block it.

I had come to pay RAAL-requisite a visit, hoping to audition a first for me: a recently-launched ribbon headphone called the CA-1a.
