Diptyque Reference loudspeaker Manufacturer's Comment

Manufacturer's Comment

Thank you very much for this detailed review of our Reference speakers.

Our primary objective is to reproduce music as naturally as possible. We are convinced that plane-wave propagation is the most natural way of reproducing an ensemble of acoustic instruments, as in a concert. In this review, we are delighted to see that you have experienced intense musical emotion.

The technical limitations you noticed with the 2023 version have been completely resolved with the new MK2 version we presented in Munich this year: new composite diaphragm frame for…

Hana Introduces Umami Black MC Cartridge

Hana has introduced the Umami Black, a new top-of-line moving‑coil phono cartridge above the Umami Red and Blue. US list price is $11,500. First public US demos are scheduled for September 6 at Quintessence Audio (Morton Grove, IL), with customer shipments beginning September 22.

What’s new
The Umami Black’s headline change is a solid diamond cantilever carrying a nude Microline stylus. The cartridge also debuts Hana’s OKD high‑efficiency generator, which combines an inverted U‑shaped front yoke with an integrated pole piece/rear yoke. According to the company, the…

Paradigm Atom v.3 loudspeaker Page 2

But I didn't find the Atoms to be rock speakers only. Their superb articulation of low-level dynamics, their abilities to soundstage and retrieve ambience, made them excellent producers of intimate chamber works such as George Crumb's Quest (Bridge 0007-2), as well as of such orchestral blockbusters as Dorati's interpretation of Stravinsky's Firebird (LP, Mercury Living Presence 90226). Fans of intelligently miked classical works recorded in sonically superior concert halls will not be disappointed in the Atom.

The Atom was also well-suited to small jazz ensembles. On the Modern Jazz…

Paradigm Atom v.3 loudspeaker Measurements

Sidebar 3: Measurements

Paradigm specifies the Atom v.3's anechoic sensitivity as 86dB/2.83V/m, which is just below average. My estimate was 86.5dB(B), which is within experimental error of the specified figure. The Atom's electrical impedance (fig.1) changes considerably over the audioband, with a minimum value of 4.4 ohms at 220Hz. The small glitch just above 30kHz indicates the presence of the tweeter's main dome resonance, which is higher in frequency than we usually see. The saddle in the magnitude trace at 66Hz indicates the tuning frequency of the port.

The fig.1 traces…

Twenty years ago, in a grungy, badly lit club in Edinburgh, Scotland, I saw a show that changed my musical life forever. There, packed together on a stage the size of a postage stamp and looking every bit as young and green as I was, were The Edge, Bono, Larry, and Adam, bashing out their bombastic new single, "Pride (In the Name Of Love)." I was smitten.…

Audio Research Reference Two preamplifier

Audio Research's first 21st-century, audiophile-quality line-stage preamplifier combines retro-tech vacuum-tube amplification and power-supply circuitry with innovative, remote-controlled gain, balance, tape monitoring, and signal routing. The price is also 21st-century: $9995. As in ARC's Reference phono section, the Reference Two's pair of vertically mounted circuit boards results in a single, relatively tall chassis.

The fully balanced gain section, rated at 2V RMS balanced (maximum output is 30V RMS) and 1V single-ended, uses eight specially selected Sovtek dual-triode 6922 tubes,…

Audio Research Reference Two preamplifier Page 2

The Ref 2 definitely changed the sonic landscape, but in ways that were subtly euphonic and ultimately pleasurable, even after long-term listening—especially after long-term listening. Given that most recordings are too bright and too edgy and most mikes too tipped-up on top, this is not necessarily a bad thing. If you like tubes, you'll like the Ref 2. If you don't...you still might like it.

Like a plush, comfortable chair, the Ref 2 put a soft cushion around the music's bottom end—not so cushy that the deep bass sank in and disappeared into the foam, but enough to add a warm,…

Put It All Together and...
The Reference Two's sonic parts were impressive, if not perfectly neutral. It had character, but because of its superb overall balance, not what I would call noticeable flaws. A lean speaker would probably mate well with the Ref 2, a plummy one not so well, but to be a truly bad match a speaker would have to almost be off the richness scale, and its bass would have to be nearly out of control. Or, one's room would have to have a serious "bump" in its low-frequency acoustics.

The Sonus Faber Amati leans toward rich and lush in the midrange, and is slightly…
