Do your speakers that go low and tight in the bass? Here's a test: Use your system to stream the tracks "Bubbles" by Yosi Horikawa and "Make us Stronger" by Ghost Rider. I heard these two tracks at the Kennedy Hi-Fi room; they were making the rounds at the show, and for good reason: They contain kick-butt bass sections, they’re 3D-spacious, and the music and sound are actually good.

The sound they made coming out of the 200Wpc, class-D NAD Masters Series M33 BluOS streaming DAC integrated amplifier ($6999; see Kal…

I generally avoid home theater rooms at an audio show because typically—and reasonably—they’ve been set up mainly with the cinematic experience in mind rather than the musical one. So I hesitated before entering the two adjoining EQ Audio Video rooms because they had screens. But with a little prodding from company owner Ed O’Herlihy—he assured me that the systems in the rooms were strictly stereo—I acquiesced. I’m glad I did.

The first system, which comprised a Musical Fidelity Nu-Vista CD player ($9000), a Nu-Vista…

Olga Oreshyna is an artist who makes, as she calls it, "non-traditional art." She begins by collecting old wood, “with scratches, cracks, knots, and other imperfections that are similar to real life." She carves it into pieces, dries it, colors it with acrylic paint or stain, and “fits [it] to a specifically designated position” among other wood pieces to create a mosaic sculpture.

One day, a friend of Olga’s pointed out that her sculptures could double as acoustic panels, and that’s how her acoustic-panel business…

Let me break it down. On the one hand, handshakes were replaced with fist and elbow bumps, real smiles by eyes smiling over masks, whispers by conversations at regular volume. There were fewer attendees than at prepandemic shows, and fewer exhibitors. That situation will surely improve with time.

On the other hand, everyone there seemed to be having a good time. You could feel it in the air, the vibe; it felt like a mixture of relief and gratitude to be back among fellow audio passionates, reuniting with old friends and familiar faces, and seeing new…

Why is Stereophile publishing its fourth review (at least) in three years of a recording of Bach's Six Cello Suites? Partly it's because the suites, which were composed ca 1720 but remained in obscurity until a young Pablo Casals rediscovered them in a secondhand sheet music store in Barcelona in 1890, contain some…

Have you ever flexed a playing card (or a few) back and forth close to your ear? They generate a little sound. According to MBL company lore, that action and sound sparked the design idea for the original Radialstrahler omnidirectional driver.

Omnidirectional speakers are rare. I can think of only a few companies that make them: German Physiks. Morrison Audio. Ohm Acoustics. Duevel. MBL (footnote 1).

The MBL 120's design, like the design of most other…

Description: Three-way standmount loudspeaker with "Radialstrahler" radial carbon-fiber omnidirectional tweeter and midrange drivers and two side-firing 6.5" woofers with aluminum-membrane cones in a rear-ported enclosure. Sensitivity: 79dB/2.83V/m into 8 ohms, 80.5dB in-room. Crossover: fourth-order Linkwitz-Riley crossing over at 600Hz and 3.5kHz and with a second-order high-pass filter below the port-tuning frequency. Frequency response: 48Hz– 15.5kHz –6dB in-room. Nominal impedance: 4 ohms. Recommended amplifier power: 200W into 4 ohms.
Dimensions: 11.8…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the MBL 120's frequency response in the farfield, and an Earthworks QTC-40 mike to measure the nearfield responses. I used Dayton Audio's DATS V2 system to determine the MBL speaker's impedance.

Designer Jürgen Reis wrote in an email that the MBL 120's sensitivity on an axis level with the top of the tweeter magnet—the recommended listening axis—was 79dB/2.83V/m. Though my estimate was slightly higher than this, at 81dB(B)/2.83V/m, this is still significantly lower than average…
