Art Dudley wrote about the Orangutan O/93 in May 2018 (Vol.41 No.5):
I needed help.
My beloved Altec Flamenco loudspeakers, which evoke sweet-smelling summer nights even when not connected to an amplifier, were overpowering my new listening room—not so much sonically, but aesthetically and practically. It was difficult to open and close the windows at that end of the room, or tend a fire in the fireplace between the speakers, or vacuum the corners behind them. I made do for the first couple of months, enjoying the speakers' taut, tactile, propulsive music-making as always, but in…
Jason Victor Serinus auditioned the MQA upgrade for the dCS Rossini in May 2018 (Vol.41 No.5):
Although it seemed that a permanent rapprochement between Democrats and Republicans might arrive sooner, dCS's day with MQA has finally dawned. The company's Rossini DAC, Rossini Player, and limited-edition Vivaldi One SACD/CD and network player can now "unfold" and render MQA files; by the time you read this, their Network Bridge should be equipped for MQA unfolding; and the Vivaldi DAC and Upsampler are being readied for MQA rendering.
While the reasons for dCS's delay in implementing…
In this 100th anniversary year of the death of Claude Debussy (1862–1918), one of the finest recordings of his music released so far is Erato's Debussy Sonatas & Trios (Erato C565142). Appropriately recorded in Paris, in two different sounding venues, with an all-star French lineup—Emmanuel Pahud, flute; Gerard Caussé, viola; Edgar Moreau, cello; Marie-Pierre Langlamet, harp; and Bertrand Chamayou, piano—the recording is replete with the unique atmosphere, color, and textures that make Debussy's music so unforgettable.
The only qualified downer on the program is the opening work, the…
This is my first trip to High End Munich, held Thursday–Sunday May 10–13 at the MOC convention center. Besides reporting for Stereophile, I am charged with scouting to make a final determination whether it "would be worth the suffering" for my Brooklyn friend Sphere, who hates to travel more than two hours to get anywhere! "Herb, just tell me, if I only attend one audio show, should it be Munich?"
For years, he only attended the Rocky Mountain Audio Fest, but this year he ventured (with my urging) to AXPONA and loved it—especially the light and beauty of the venue. But Sphere only wants…
Everything you've heard is true. Lufthansa really is among the world's finest airlines. (I say that as an uncomfortable and often unwilling traveler who has had nothing but perfect flights on Lufthansa), Munich is one of the cleanest, most attractive, and most easily traveled cities in Europe. And Munich High End is, without a doubt and by a stunning margin, the greatest audio show on Earth, period. Nothing I could say—nothing—can prepare you for the sheer scale of the venue, the number and variety of exhibits, the quality of those exhibits, and the exciting, carnival-like vibe of Munich High…
Scheduled to ship in early autumn, the Hegel 590 ($12,000) is poised to become the Norwegian company's new flagship integrated amplifier. With a power supply 50% larger than that of Hegel's previous top-of-the-line integrated (the H360), the 590 operates in class-AB, delivering 301Wpc and maintaining low distortion with a feed-forward system that kicks in as needed. As with previous Hegel products, its D/A section uses a built-from-scratch master clock, rather than an off-the-shelf chip, and it does PCM up to 384kHz, and up to DSD256 (DSD over PCM).

As I exited my hotel on Friday morning, a portion of my favorite Nick Drake lyric popped into my mind: A day once dawned / And it was beautiful . . .
Friday's weather was no less spectacular than Thursday's—yet from the moment I arrived there, the MOC was mobbed with attendees who weren't at all bashful about spending the day indoors. Perhaps the interior sunniness of the glass-and-steel structure helped: I would certainly chafe at spending such a beautiful day roaming the dark halls of some glum hotel.
Whatever the reason, I couldn't shake the impression that a lot of audio…
. . . is here and Art Dudley feels that in the age of streaming, there is still life in the CD medium, as typified by Rega's new Apollo player. Art's enthusiastic review is joined by reviews of EgglestonWorks' 20th anniversary Viginti speaker; Bryston's BP173 preamplifer; Rogers High Fidelity's single-ended 65V-1 amplifier; the NOS Formula xHD DAC from Italian company Aqua Acoustic; and comparisons between preamplifiers from Ayre and PS Audio.
Jim Austin concludes his technical analysis of the controversial MQA format with an interview with Bob Stuart, where he talks about "post-Shannon…
So, folks, here are a couple things you need to understand about Munich High End 2018:
As a rule, Europe brings to audio a different aesthetic and perspective than America—they are way less into giant, million-dollar, solid-state amplifiers and way more into low-power tube amps. And . . . they are definitely into horn loudspeakers in a way that most Americans cannot fathom. I was in Munich for three days and I could never have covered all the rooms featuring horn speakers. Can you imagine that many horn speakers at CES, RMAF, or AXPONA? I can't.
Mainstream taste in American high-…
