It had been too long since I’d heard Vinnie Rossi’s gear, so I was pleased to encounter the brand’s Brama Gen2 preamplifier ($38,995), Brama Gen2 monoblocks ($59,995/pair), and Rossi himself. The system also featured Rockport Technologies’ new Lynx loudspeakers ($78,000/pair in Satin Titanium Metallic) and the Mola Mola Tambaqui DAC ($13,500). I was curious to hear how it all came together sonically.

In the Renaissance Hotel’s Connection room, Quintessence Audio of Morton Grove, Illinois presented Boulder’s new 1151 power amplifiers ($48,000/pair as monoblocks, see Stereophile’s June issue), a 1110 preamp ($24,000), and a 1108 phono preamp ($24,000), all making their AXPONA debut.

Stenheim, VTL, and Nordost returned as AXPONA system partners, joined this year by several notable additions. The analog front end featured Grand Prix Audio’s Monaco 3.0 turntable ($56,250) with Fuel Station battery power supply ($15,250), Kuzma’s Safir 9 tonearm ($23,140), and a Lyra Etna cartridge ($8995). Nordost showcased four rare Odin Gold power cords ($43,999), alongside its familiar Odin 2 and Valhalla 2 cables and a broad range of accessories. Digital duties had shifted from last year’s dCS Rossini Apex to the full Vivaldi Apex stack: DAC ($46,500), Upsampler ($27,000), and Master Clock ($21,000).

New York–based dealer New Life Audio teamed up with California distributor Hear This—representing WestminsterLab and Von Schweikert Audio—to build a system around those two brands. On a Bach Violin Concerto, played with characteristic sweetness—if not period authenticity—by Belgian violinist Arthur Grumiaux, both tone and texture came through with striking fidelity.

Once again, my time in the Vandersteen room provided copious pleasure. Plus, it came in two installments: listening time in the inner sanctum, and chat time with Richard Vandersteen and Brad O’Toole in the entrance chamber. If that sounds rather exotic for a two-room hotel suite, you needed to be there.

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.

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.
