I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the GoldenEar Triton One.R's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield responses. I removed the loudspeaker's front and side grilles for the nearfield measurements but left them in place for the farfield measurements (footnote 1).
The Triton One.R measured very similarly to the original Triton One. As with the original, GoldenEar specifies the One.R's sensitivity as 92dB/W/m. My estimate was 91.2dB(B)/2.83V/m, which is both within…
Musical Artisans is proud to host the Nagra HD Line Show on December 6 and 7 in Chicago, with special guest René LaFlamme from Nagra.
A full Nagra HD system including the HD Preamp, HD Amps, and their most recent introduction, the HD DAC X will be playing in the main listening room. Rockport Cygnus loudspeakers and a full suite of Argento Audio cables will reveal the extraordinary magic of these world class components.
In addition to hi res digital files, vinyl will be playing on the exquisite De Baer Saphir turntable with Onyx tonearm, and René will be playing analog tape on…
Following in the lineage of such iconic dub music masters as Osbourne "King Tubby" Ruddock and Lee "Scratch" Perry, producer Adrian Sherwood is the UK's contemporary pioneer of dub: the reverb-filled, beats-rattling, bass-thick music that erupted from "sound system" parties in Kingston, Jamaica in the 1960s.
In the 1980s, London-born Sherwood cast a wide net with his On-U Sound Records label. He has produced, mixed, or remixed artists as diverse as KMFDM, Depeche Mode, Garbage, and Nine Inch Nails. But if you ask him, he'll cite records with dub innovator Lee "Scratch" Perry—Time Boom X…
Everyone who reads my loudspeaker reviews knows: I wish box speakers did not sound like box speakers. Plus! I wish all speakers sounded focused and transparent like LS3/5a's or vintage Quads. I also want them to be uncompressed and play large, with window-shattering power and floor-shaking bass. And while I'm wishing . . . I'll take a little glow and sparkle and voodoo magic as well.
Unfortunately, few loudspeakers do all that. And the ones that can cost crazy cash.
But there might be hope.
I have discovered a radically engineered floorstanding speaker that maybe, just…
My initial listening with the Manger p1s suggested they might be able to reproduce the enormous scale and antibourgeoise zeitgeist of one of my favorite cosmic bands, KMFDM (which stands for Kein Mitleid für die Mehrheit, or No Pity for the Majority). KMFDM's signature song, "Salvation," always sounded pretty good on the DeVore Fidelity Orangutan O/93s, which got the tones and texture right. And it always sounded a little better on the Zu Audio Soul Supremes, which played at the necessary loudness levels. But neither speaker delivered the penetrating high resolution this composition requires…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the Manger p1's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield responses. When I picked up the Manger speakers from Herb Reichert, he told me that he suspected that the p1's sensitivity was lower than the specified 89dB/W/m. My estimate was indeed lower, at 85.6dB/2.83V/m. Manger specifies the impedance as 4 ohms, which would mean that the p1 is actually drawing 2W from the amplifier with a 2.83V signal. The solid trace in fig.1 shows that the…
Manufacturer's Comment
I would like to thank Stereophile for this well-written and excellent review.
As a designer and manufacturer of a unique loudspeaker technology, it is satisfying to know that a magazine exists with a well-intentioned and competent editorial staff. In the case of our review, Herb Reichert perfectly describes his perception of the particular sound reproduction abilities of the Manger sound transducer, which is at the heart of all Manger loudspeakers. The research that led to the invention of the Manger sound transducer was all about a better transient…
I was less than thrilled by Editor-in-Chief Jim Austin's suggestion to review the solid-state Krell K-300i integrated amplifier ($7000, plus an additional $1000 for the optional DAC). I had recently reviewed another $7000 integrated amplifier, the quite different hybrid Aesthetix Mimas, and while I ended up liking the Mimas a whole lot, I felt decidedly lukewarm about having to recalibrate expectations for another integrated, especially one that costs far less than my reference Dan D'Agostino Progression monoblocks ($38,000/pair) and whose DAC option is a fraction of the price of my…
