AXPONA 2025

First unveiled in passive display at Munich High End 2024, the new D’Agostino Pendulum Integrated amplifier made its US consumer audio show debut in two places at AXPONA 2025: a hallway setup—where listening was possible only at close range—and in a room sponsored by Innuos.

Justin Weber of Ampsandsound greeted AXPONA with the world premieres of two products hand-built in his Aliso Viejo, California, factory: the Black Pearl XL SE 300B amplifier and the horn-loaded Sasquatch three-way speakers.

Treehaus: The name conjures bark and birdsong, but its products are pure Klangbildvergrößerungsmaschinen*. Rich Pinto of Treehaus Audiolab creates gear that fuses sonic beauty with sculptural woodwork and the control of a practiced hand. All circuitry and internal construction are the work of Radu Tarta, a designer known for his meticulous builds.

At AXPONA 2025, Jonathan Halpern of Tone Imports and Matt Rotunda of Pitch Perfect Audio teamed up in room 2025. Very au courant. I first met Halpern and speaker designer John DeVore years ago, when both worked at Steve Mishoe’s In Living Stereo, a high-end store in New York. Their careers have long intersected—and so has their gear.

Mark Sossa of Virginia-based distributor Well Pleased AV brought a sweet lineup to Chicago, including the world-premiere Merason Mountain DAC ($20,000).

Rogue Audio’s Bill Magerman and Nick Fitzsimmons introduced the RP‑3 at AXPONA 2025—a new preamp that’s tube-equipped and unmistakably Rogue. The RP‑3 ($3495) is a feature-packed machine with two 12AU7 tubes in a mu‑follower design, a remote control, home-theater bypass/unity-gain inputs, three sets of RCA inputs, and two pairs of XLR inputs. Also on-board: a mono button, a tube-based high-power headphone amp, linear power supplies, and a three-year warranty. Like all Rogue gear, it’s made in the USA.
