Voilà encore un client heureux de simplifier son installation et notamment sa source numérique avec un EMM Labs Inc. MA-3 aux performances remarquables, d’autant qu’il embarque la nouvelle version du firmware certifiant le MA-3 Roon Labs ready.
Le contrôle de volume est le même que celui installé sur le fabuleux DV2 (3 fois plus cher) sans destruction ou modification du signal, et le steamer n’est autre que celui du NS-1, une référence !

Ce qui, tout compte fait, place le Meitner MA-3 dans la catégorie des produits accessibles ! 😁 🎶🎵🎶 ... Voir plusVoir moins

KoetsuStereophile : Recommended Components 2021 Edition Phono Cartridges

++++ Koetsu Onyx Platinum ++++

As AD noted in the December 2018 issue, "To compare the specifications of Koetsu's 15 different models is to glimpse little in the way of variety: all Koetsu cartridges have the same recommended ranges of VTF and load impedance; all of their platinum-magnet cartridges have the same 0.3mV output, while all their samarium-cobalt magnet cartridges output 0.4mV."

That said, it turns out the Onyx Platinum's nominal mineral was the first nonwood, nonmetal material used in a Koetsu cartridge—and its nominal element went on to be used for the magnets in all of the company's top-end cartridges. Whether that makes the Onyx Platinum the pivotal model in Koetsu's line is anyone's guess—but AD was smitten by its abilities to let music sound colorful, forceful, well textured, and downright human when called for.

++++ Koetsu Rosewood Signature Platinum ++++

Designed by Fumihiko Sugano, son of Koetsu founder Yoshiaki Sugano, the Koetsu Rosewood Signature Platinum exhibits moderately low output (0.3mV), moderately low resistance (5 ohms), expects a downforce of 1.8−2.0gm, and is priced more or less in the very middle of Koetsu's product line.

Of his time with the Rosewood Signature Platinum, HR wrote that "this Koetsu, with its lacquered rosewood body, silver-plated copper coils, quadrahedral stylus profile, boron cantilever, and platinum magnet, gave me a sixth-row seat for [a] long-cherished recording."

When Herb loaded it with 100 ohms, "the result was an exceedingly rich and unaffected sound," and the Koetsu "seemed engineered to do nothing but hold my attention—my pleasurable fascination—as it showed me the art behind the music." Later comparing the Koetsu with a budget Audio-Technica moving magnet, HR wrote that he heard sublime ease and dramatic understatement: "Immediately, I grasped how unsubtle the VM95C was. I also received what felt like infinite amounts of micro-level information." However, although he felt that he didn't get closer to the living performers, as he had with the cheap cartridge, the Koetsu "did what it was designed to do: transform the quotidian into the marvelous."

++++ Koetsu Rosewood Mono ++++

Nominally, the Koetsu Rosewood Mono has nothing up its sleeve: It is, indeed, a Koetsu Rosewood cartridge—an enduringly popular moving-coil model and surely among the very first wood-bodied cartridges to cross our path—and it is, indeed, intended for use only with monophonic records. (Whether it contains a true single-channel motor or a stereo motor strapped for mono, MF doesn't know: Koetsu did not provide specifications.)

Extrapolating from the more common stereo Koetsu Rosewoods, MF estimates the Mono's output as 0.4mV, its internal impedance as 5 ohms, and its tracking-force range as 1.8−2gm. Under the Rosewood Mono's stylus, the recent mono reissue of Duke Ellington's Masterpieces by Ellington was "in full bloom," according to Mikey, "if somewhat at the expense of bass attack and transient bite." His conclusion: the Koetsu Rosewood Mono is a good choice "if your system needs a bit of softening of transients."

++++ Koetsu Rosewood Standard ++++

Among moving-coil cartridges that bear the Koetsu brand—products as reliably boxy in shape as they are exotic in the materials used for their bodies—the Rosewood Standard is among the most affordable. Mounted inside its rosewood housing is a motor built with samarium-cobalt magnets, 99.9999%-pure copper coils, and a boron cantilever, to which is bonded a stylus with a hyperelliptical tip.

Specs for the Rosewood Standard include an output of 0.45mV, an impedance of 5 ohms, and a recommended downforce of 1.8–2gm. After using Koetsu in his system, HR praised the Rosewood Standard's tight imaging and "slam-dance excitement," while noting that "[m]ost impressive was how the Koetsu exposed extremely subtle, almost subliminal instrumental textures . . . while making nearly imperceptible changes in those instruments' tonalities seem beautiful and important."
