Phasemation d\u00e9crit l’\u00e9tage phono EA-350 comme une \u00e9lectronique “toute en composant discret, avec diff\u00e9rents \u00e9tages uniquement sym\u00e9triques sans contre-r\u00e9action dot\u00e9 d’entr\u00e9es de sym\u00e9triques ou asym\u00e9triques permettant d’extraire la r\u00e9alit\u00e9 de la musique et de la passion de l’artiste”.<\/div>\n<\/div>\n<\/div>\n

D\u00e8s la premi\u00e8re \u00e9coute du EA-350, nous avons \u00e9t\u00e9 imm\u00e9diatement s\u00e9duits, une impression confirm\u00e9e par le magazine de d\u00e9cembre de Haute-Fid\u00e9lite qui l’a consacr\u00e9 par le label “Meilleur Achat du Mois”.<\/span>Avec un prix contenu de 3900\u20ac, cet \u00e9tage phono construit en vrai double mono dispose de trois entr\u00e9es commutables MM ou MC dont deux avec entr\u00e9es RCA ou XLR, la possibilit\u00e9 d’\u00e9couter soit en st\u00e9reo ou bien mono (sommation des canaux pour une lecture horizontale) avec deux courbes d’\u00e9qualisations, filtre infra-grave ainsi qu’une fonction d\u00e9gauss active.<\/span><\/p>\n

\n

La partie MC de l’EA-350 utilise des transformateurs \u00e9l\u00e9vateurs issus des derni\u00e8res \u00e9volutions contenues dans les transformateur haut de gamme Phasemation T-2000 (10 000\u20ac) qui permet d’utiliser un vaste panel de cellules telles que des cellules basses (Lyra, Phasemation, Mutech, My Sonic Lab, Ortofon, Audio-Technica, Hana) ou m\u00eame des cellules hautes imp\u00e9dances (Benz, EMT, Denon DL-103).<\/p>\n

Le verdict de Haute-Fid\u00e9lit\u00e9 est limpide : “Avec le EA-350, Phasemation nous propose un \u00e9tage phon bougrement musical et tr\u00e8s universel. Objectivement parlant, ce pr\u00e9amplificateur adopte des solutions techniques tr\u00e8s int\u00e9ressantes avec une excellente qualit\u00e9 de fabrication. Les possibilit\u00e9s d’association et de r\u00e9glages rendent l’appareil utilisable dans toues les configurations, MM ou MC, st\u00e9r\u00e9o ou mono. Enfin, sa restitution s’impose comme un des plus r\u00e9alistes, comme une des plus envo\u00fbtantes que nous ayons eu l’occasion d’appr\u00e9cier avec un pr\u00e9amplificateur phono dans ce cr\u00e9neau de prix. Recommand\u00e9.<\/p>\n<\/div>\n<\/div>\n

Phono AmplifierEA-350<\/h2>\n
<\/p>\n
An all discreet, all step symmetric non-feedback phono amplifier that supports balance inputs and draws out the music\u2019s reality and the artist\u2019s passion<\/div>\n<\/div>\n<\/div>\n
\n

Product Outline and Concept<\/h3>\n

Having in mind that \u201canalogs too have a lot more to go,\u201d we expanded the product line-up of EA-1000, EA-500, EA-300, EA-200 and phono amplifiers due to non-feedback circuits for lovers of analog discs.<\/p>\n

This time as the product to be a touchstone of a semiconductor phono amplifier, we brushed up all of the functions from the interior MC transformer to the circuits of EA-350<\/p>\n<\/div>\n

\n

Main feature<\/h3>\n
\n

I. Inside is an MC transformer for balancing which is accomplished the first time for this class<\/h4>\n

Last year, using our knowledge gained from making T-2000 which sparkled having won many awards last year, we built in a step-up transformer with a special split winding structure supporting balanced transmissions of a 26dB gain and this makes an MC balanced transmission.<\/p>\n

Three input terminals are equipped and MM\/MC switching is possible for each. (Inputs 1 and 2 support balanced inputs)<\/p>\n<\/article>\n

II. A 10mm thick aluminum material is used on the front panel and the chassis is elegant and strong and it is structured following the designs of CA-1000 and T-2000.<\/h4>\n

We adopted a strong housing structure that is composed with a 10mm thick slant aluminum panel for the front, a 1.6mm thick copper platted steel plate chassis base, and a 1.6mm thick copper platted steel plate cover and this preserves the rigidity and decreases the magnetic strain.<\/p>\n

In addition, the elegant designs of CA-1000 and T-2000 are adopted and the played sound can be enjoyed with elegance, overwhelming realism, a panoramic stage, high resolution, and high S\/N.<\/p>\n<\/article>\n

III\uff0eV-I \/ I-V conversion type full-stage symmetrical non-feedback amplifier circuit due to all discreet parts<\/h4>\n

The negative feedback amplifier which is the mainstream of modern amplifiers constantly compares the input and output signals for both the semiconductor and vacuum tube and this difference can be amplified with high precision at low cost because it is amplified as an input signal. However, there is a time delay between the input and output signals which cannot be solved theoretically and this generates a TIM distortion and the like and this is a big reason why sound satisfaction cannot be attained from negative feedback amplifiers.<\/p>\n

At Phasemation, amplifiers of semiconductors and vacuum tubes are all composed of non-feedback amplifiers. For non-feedback amplifiers, there are no amending operations like the negative feedback amplifiers and therefore high precision\/technology of structured parts and circuits are required. As a result, there are no information remains of the sound source (record) but is played fully 100% and in terms of sound quality, it can play the music with excellent inspiration, dynamics, and shadowed (or the like) expressions.<\/p>\n<\/article>\n
