Der größte und teuerste Vollverstärker von Accuphase im
AUDIO-Exklusivtest.

Text: Joachim Pfeiffer

eine großen Überraschungen auf den ersten Blick: Das neue VollverstärkerFlaggschiff von Accuphase, der E-550, ist minimal höher und einen Hauch schmaler geraten als sein legendärer Vorgänger
E-530, die ehedem mattierten Seitenwangen sind nun hochglanzpoliert, und der Preis sinkt um glatte 1000 auf 7900 Euro. Das neue Modell sieht nicht wirklich neu aus,
das alte nicht wirklich alt. Also ein kaum zu erkennendes Facelift?
Völlig falsch getippt! Das im Class-ABetrieb fahrende Accuphase-Flaggschiff klotzt  um im Bild zu bleiben  mit einem neuen Antrieb. Dessen SchlüsselFeature ist zweifelsfrei die anspruchsvolle
Lautstärkeregelung AAVA (Accuphase
Analog Vari-gain Amplifier), die bislang nur den wesentlich teureren ReferenzVorstufen aus gleichem Hause vorbehalten blieb. Was verbirgt sich dahinter, welchen
Nutzen haben die Besitzer davon?
In herkömmlichen Verstärkern, so auch im E-530, verantwortet ein Potentiometer die Lautstärkeregelung. Mit einem Dreh nach rechts wird's lauter, in Richtung links wieder leiser. Und egal, wie ausgefuchst solch ein Poti auch konstruiert und q

Review in STEREOPLAY magazine (Germany), July 2005 Accuphase Integrated Amplifier E-213 Silent Running by Dalibor Beric An Accuphase amplifier of the E-200 series has ever since been the "dream machine" of many audiophile music lovers. The new E-213 is now the culmination of the virtues this series of integrated amplifiers had to offer. Silence can be very impressive. It will move you when you are to realise how little one can hear during a calm night in the desert. And it is nevertheless remarkable as...

Test & Technik I Endverstärker 120 stereoplay 3/2007 www.stereoplay.de ccuphase: Dieser Name flößt Respekt ein. Weil er für Modellkonstanz, Langlebigkeit sowie stets wiedererkennbaren sehr guten Klang steht. Doch es wird gern übersehen, dass in Japan innovative Entwickler sitzen, die es meisterlich verstehen, neue Ideen mit klassischbewährten Schaltungen zu verbinden. Ein Beispiel ist die ausgefeilte Class-A-Technik des Endverstärker A 45 für 7700 Euro. Diese Betriebsart, bei der ständig ein...

Review in STEREO magazine (Germany), June 2004 Power Amplifier Accuphase P-5000 Rational Arguments by Holger Barske Something's going on in the best known of Japan's champagne wine cellars: Accuphase have completed their line of power amplifiers by launching the P-5000. They owe it to themselves, those busy engineers from Yokohama: in the beginning of this year they gave us merely their second biggest pre-amplifier for testing (STEREO/January 04), namely the C-2400, yet they could completely sweep...

STEREO  01/2015 What is so special about this? Alright, one doesn't have to be an insider to recognize the C-2120 and P-4200 as Accuphase amps. But what makes the amps from Japan's noble forge so special? Stereo took a closer look. Stupid question Mr. Böde, no? After all one can tell the origins of this Pre- and Power Amp combination on first sight: thick champagne colored front plates with very fine brushed surfaces, the classic structure of input selector and volume control, distinctive meter...
