AXPONA 2025

Pushing through the AXPONA crowd, fueled by caffeine and the ambient buzz of the show floor, I made my way toward the Klipsch room, where the newly revised Klipsch La Scala AL6 was making its debut. Also featured was the Unison Research S6 integrated amplifier, which I lauded in a recent Stereophile review.

As the former owner of an Aragon 8008 power amplifier, I was curious to see how the company’s products have evolved. I used to admire the amp’s V-shaped heatsinks and felt lucky to own it. It was the second high-end amplifier I bought, and a major upgrade over the bright-sounding Adcom that came before it.

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.

Room 1225 with Fidelity Imports offered a jolt of musical energy—vinyl spinning, bookshelf speakers punching, and a vibe that was more “groove and grind” than “rise and shine.” Even early in the day, the system sounded wide awake.

Tony Santos of Stereo Haven and Mike Pranka of Toffco brought a Well Tempered Lab turntable—a common sight in rooms with standout analog sound. In room 624, the Well Tempered Lab Amadeus, for which Pranka serves as US distributor, delivered a sense of musical ease and warmth.

In partnership with Playback Distribution, TEAC debuted its new AP-507 stereo power amplifier ($2799) early in the day, luring this reviewer with strong coffee and stronger specs.

At Munich High End 2024, my biggest discovery was Switzerland’s Wattson Audio. It’s easy to hear a sonic kinship between Wattson and its new owner, CH Precision—an affinity that helped explain CH’s acquisition of the company last year.
