In two adjacent rooms on the 14th floor of the Renaissance Schaumburg Hotel, Innuos launched its latest Stream1 and Stream3 devices. Conceived as “the gateway to high-performance music,” the Stream series works with the Innuos Sense app. The app’s latest additions include a portal to the IDAGIO classical-music streaming service, Spotify Connect, Qobuz Connect, and more.

The entry-level Stream1 can be outfitted with an external LPS1 power supply for improved sound. It comes with a USB audio output and supports dedicated add-on modules for a Standard DAC Board, Performance DAC Board…

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.

AXPONA provided the opportunity to speak with Rick Santiago, who, with business partner Ted Moore, bought Aragon from Klipsch. Santiago—now CEO and co-owner of Indy Audio Labs, which designs and manufactures Aragon and Acurus gear—studied Mike Kusiak’s original Aragon circuits…

John Atkinson reviewed the Canton Reference 7K in September 2021, and Ken Micallef followed up. The 7K ended up in Class A, Restricted Extreme LF,…

The driver array of the Canton Reference 5 places the two twin woofers at the bottom, the tweeter in the middle, and the midrange driver on top. This arrangement is less common than tweeter on top. I asked the Canton Design Team about this choice: "The midrange driver is primarily responsible for spatial focus and soundstage representation. For this reason, we aim to design it as broadband as practically feasible and position it as optimally as possible for such localization-critical tasks."

In his measurements, John Atkinson often notes the degree to which the tweeters are above…

I measure loudspeakers in our living room. I move the furniture to the sides, place the speaker on my computer-controlled Outline turntable, raising it so that the tweeter is midway between the floor and ceiling, and fire the speaker along one of the room's diagonals. That maximizes the anechoic time window before reflections from the room boundaries arrive at the microphone. However, I was unable to lift the heavy Canton Reference 5 as high off the ground as I would have wished. I therefore measured the response and dispersion with the microphone at 1m rather than…

A Technics SP-10R and SME M2 12" tonearm were mounted to the new Fern & Roby Richlite-and-walnut plinth ($22,500). A ModWright PH 9.0X phono stage ($4750) and Miyajima Carbon cartridge ($2999) completed the analog front end.

Digital gear included a Weiss Helios DAC ($21,995); a Network Acoustics Origin 5V PSU and DAC cable ($2100); a Muon Pro streaming system ($2620); an Eno2 streaming system ($1610); and…

For me, Volti Audio systems from Greg Roberts have become perennial standouts at audio shows. Their purity, vivid dynamics, and—perhaps most important—their rich, natural tone create an immersive presentation in which all types of music truly swing and sing.

This year’s AXPONA was no different. Roberts officially debuted his new 104dB/W/m, 20Hz–25kHz Vittora loudspeaker system, which includes two main Vittora loudspeakers, two ELF12 subs, two ELFamp amps, and one ELFpre ($50,000 for the lot).

The chain featured an Innuos ZENith music server ($6699) feeding a Mojo Audio…

In room 1521, I caught up with Wayne Colburn—longtime preamp wizard for Pass Labs (and Threshold Audio before that)—and Kent English, the company’s veteran head of sales. Colburn was debuting his new 85lb XS Pre 2 line-stage preamp ($55,000), which he called a step up from the XP-32.

Colburn doesn’t consider the XS Pre 2’s design “excessive,” despite its name. He noted that the preamp uses separate boxes for the left channel, right channel, and power-supply/display, and described it as “more resolving, with a lower noisefloor. It sets a new standard for us.”

The power…
