Mastersound: Teaching Old Tubes New Tricks

Mastersound's Antonio Ferro showed four products, including the flagship Spazio preamplifier ($21,500; prices approximate and converted from euros). It's a multidrive‑stage preamplifier that uses six ECC82 and three ECC83 tubes, provides RCA and XLR inputs and outputs, and includes MM/MC phono inputs.

The new Mastersound single‑ended PF200 monoblocks ($100,000/pair) deliver 200W in class‑A via eight 845 tubes, feature automatically adjustable bias, and provide one XLR input.

Resembling the Mastersound 845 that I reviewed for Stereophile—now with updated…

Tune Audio, Trafomatic, Rockna: An Enigma in Sound

This room presented a delightful enigma: a system consisting of largely unfamiliar-to-me brands that eclipsed much of the established competition. It delivered intricate detail and clarity with a sense of wholeness.

The system featured a Rockna Wavedream Reference Signature DAC ($28,500, all prices approximate and converted from euros), digitally interfaced with a Rockna Wavelight Server ($6900). The signal then passed through a Trafomatic Audio Lara line preamplifier ($10,900) before being amplified by a Trafomatic Audio Rhapsody power amplifier ($18,000). The loudspeakers…

Joseph Audio's Jeff Joseph teamed with Nick Doshi to present another fantastic‑sounding room at High End Munich.

Munich Was Wunderbar. Vienna's Next—If You Can Afford the Room

This photo of the vast Munich venue, taken near closing time on the last day of the 2025 audio show, wraps up Stereophile's coverage.

Despite the impact of the Trump tariffs, Munich attendance figures were again impressive.

While the Munich event may not be audio's most popular—depending on how you count attendees, the Hong Kong, Warsaw, and AXPONA…

Ferrum's Firmware Finesse: An International Ear for Audio

Drawn to the impressive sound and compact design of Ferrum's Polish-made, relatively affordable components, I was eager to visit the brand's booth and learn about the new 2.0.0 firmware update for the $2800 Wandla DAC. The update introduces Ferrum Streaming Control Technology (FSCT), which enables remote control of streamers and displays title and artist information on the DAC's touchscreen.

The new code also lets Wandla owners control volume over USB between the DAC and a computer, connect via I²S, and move more easily among inputs. According to Ferrum CEO Marcin Hamerla, metadata…

Marten Goes Extreme

In the Marten Audio room—where Marten loudspeakers partnered with Audia Flight electronics and Jorma cabling—the main objects of attention were the striking Marten Coltrane Quintet Extreme loudspeakers. At $415,000/pair (all prices approximate when converted from euros) and with a production limit of just 10 pairs, these speakers are for listeners who don't merely gawk at unobtanium—they bring it home and plug it in.

The Coltrane Quintets were driven by Audia Flight Strumento N°8 Signature monoblocks ($98,000/pair) and a Strumento N°1 Signature preamp ($52,000). The rest of the…

Qobuz Connects, Solomon Detaches

From Munich's English Gardens to the Marienplatz, all audiophiles seemed to be talking about Qobuz Connect. I sat down over lunch with David Solomon to get the skinny.

Qobuz Connect, the French music-streaming company's answer to Tidal Connect, is a one-stop solution that lets you manage your music library and control streaming with the Qobuz app. To quote the company's website, "With Qobuz Connect, you can seamlessly switch from your headphones to your hi-fi system, and your music will continue from the exact moment you left off."

"If you use Qobuz Connect, there are no other…

Manger's Red-Hot p2 Speaker: Attractive and Exacting

A chance encounter with Daniela Manger, CEO and engineer of Manger Audio led me to the exhibit with the company's latest offering: the striking red, p2 floorstander ($15,000/satin matt lacquer - $17,900/Ultra high gloss), whose optimized driver has a stronger motor for faster response and more transient information. The specified frequency range is 30Hz–45kHz. (See Herb Reichert's review of the Manger Audio p1.) This passive speaker was demonstrated with (and without) a standalone external crossover, the SPL Crossover Mk2.

Manger told me that her latest "bending mode" driver, designated…
