Der Envy ist jedoch mehr als nur ein paar schöne Holzpaneele und eine Reihe von ausgefallenen Röhrenoptionen. Er hat Power – und zwar jede Menge – auch für schwer anzusteuernde Kopfhörer, was ihn für Fans von Abyss 1266 oder Susvara attraktiv machen dürfte, und reichlich Anschlussmöglichkeiten, die ihn ein anständiges Heimsystem integrieren. Mit anderen Worten: ein komplettes Paket, selbst für die anspruchsvollsten HiFi-Liebhaber. Feliks Audio EnvyDer Feliks Audio Envy ist ein Flaggschiff unter den Class-A-Röhren-Kopfhörerverstärkern mit Vorverstärkerfunktionen und einer Ausgangsleistung von bis zu 8 W. Der Envy ist jedoch mehr als nur ein paar schöne Holzpaneele und eine Reihe von ausgefallenen Röhrenoptionen.Er hat Power, jede Menge davon auch für schwer anzusteuernde Kopfhörer, die sich für Susvara-Fans als attraktiv erweisen sollten, und eine anständige Menge an Anschlussmöglichkeiten, die auch in ein anständiges Heimsystem passen.Der Envy ist ein Class-A-Kopfhörer-Röhrenverstärker mit einem transformatorgekoppelten symmetrischen Ausgang und einem Halbleiter-Gleichrichter. Das Herzstück der oben montierten Röhrenkonfiguration sind zwei recht kräftige und nicht gerade preiswerte H300B-Leistungsröhren.Feliks Audio hat zwei H300B Envy-Optionen herausgebracht, um den Geldbeutel zu schonen. Die Envy-Basiseinheit enthält zwei passende Electro Harmonix Gold 300B-Leistungsröhren und die Performance Edition enthält einen Satz passender Fullmusic 300B Trioden-Leistungsröhren mit Goldgitter.Feliks Audio Envy VERSTÄRKERZwei wichtige Punkte: Der erste ist die Single-Ended-Class-A-Topologie des Envy, um unerwünschte Verzerrungen so weit wie möglich zu vermeiden.Der zweite ist die Verwendung einer Halbleiter-Gleichrichtung, um den Ausgang straff und druckvoll zu halten und den traditionellen Röhren-Gleichrichter-Sog” oder schlaffe Low-Ends zu vermeiden. Dies ist etwas, was der Envy außerordentlich gut kann.Der Envy-Verstärker ist in Punkt-zu-Punkt”-Technologie gefertigt, d. h. jede Komponente ist direkt mit der nächsten verdrahtet. Alle Punkt-zu-Punkt-Verbindungen sind speziell aus einkristallinem Kupfer (UPOCC) mit Teflon-Isolierung gefertigt.Die Eingangsseite beginnt mit einem Alps RK27-Potentiometer, gefolgt von einem zweistufigen Vorverstärker mit den CV-181-T MKII Leistungsröhren. Und stickstoffgefüllte Jantzen Superior Z-Cap-Koppelkondensatoren.Sowohl die Ausgangstransformatoren als auch der Netztransformator wurden von dem polnischen Transformatorenspezialisten EDIS Ogonowski speziell angefertigt.Der Verstärker verfügt über eine vollautomatische Vorspannung und seine elektrische Schaltung ist rückwirkungsfrei ausgelegt. Die Endstufenröhren werden mit Gleichstrom beheizt, wobei eine spezielle Schaltung dafür sorgt, dass die Röhrenheizung von der Stromversorgung des Audiopfads getrennt ist.Die Stromversorgung für die Anodenspannung ist auf Halbleitern aufgebaut und basiert auf MOFSET-Transistoren und rauscharmen Stromquellen.Für die symmetrischen XLR-Ausgänge hat Feliks Audio symmetrische Lundahl-Transformatoren in Audioqualität verwendet, wobei die Quellenauswahl durch Schwachsignalrelais gesteuert wird, die direkt hinter den Eingangsanschlüssen platziert sind, um das Grundrauschen und mögliche Störungen zu reduzieren.Ästhetisches DesignDer Envy ist ein echter Hingucker. Mit 15,1 kg ist er auch ziemlich groß und schwer, aber nicht so groß, dass er in einem Standard-HiFi-Rack Probleme bereiten würde. Das Hauptproblem beim Aufstellen des Envy ist die Höhe, da die H300B-Treiberröhren ihm ein ziemlich hohes Profil verleihen und etwas Platz zum Lüften benötigen.Wenn man den Envy auf das oberste Regal stellen will, sollte man so viel Platz wie möglich in der Höhe haben. Er sieht ohnehin wunderschön aus, so dass ein mittelgroßer Platz im Regal ein Verbrechen wäre.Die Ästhetik besteht hauptsächlich aus zwei stark gemaserten, geölten Holzblöcken, die um ein schwarzes Chassis gewickelt sind, das die Blöcke miteinander verbindet.Die Holzauswahl ist wunderschön und erinnert an die Ästhetik der Verstärker von Auris Audio. Aber nur eine Nuance schärfer an den Kanten und Ecken.Das eloxierte Metallgehäuse wird durch einen zentralen dünnen Streifen an den Seiten hervorgehoben. Nach vorne hin wird es jedoch breiter und zeigt eine Retro-Ästhetik aus den 40er Jahren mit einem großen, zentral positionierten Potentiometer.Auf beiden Seiten des Potentiometers befinden sich die Kopfhörerausgänge und kleinere Lautstärke-/Impedanzregler in passendem schwarz eloxiertem Design.Der Ringkerntransformator befindet sich in einem ähnlichen schwarzen Metallgehäuse auf der Rückseite des Envy. Direkt dahinter befindet sich die trapezförmige 2 x 2 Röhrenkonfiguration, die von oben bestückt wird.Der Verstärker wird außerdem mit zwei passenden, schwarz eloxierten Metallschienen geliefert. Die sicher mit Low-Profile-Schrauben direkt vor den Treiberröhren angebracht sind. Die Schutzvorrichtungen sind persönlich, aber es ist völlig optional, je nachdem, wie Sie das Aussehen mögen.Letzter Gedanke zu Feliks Audio EnvyDer Feliks Audio Envy ist ein absoluter Knaller unter den Röhrenverstärkern. Der süße Obertonbereich des Envy, die massive Staging-Qualität und das enorm beeindruckende dynamische Low-End sorgen für ein sehr angenehmes Hörerlebnis.Mit den Optionen Eiche, amerikanisches Walnussholz, Zebrano, Sapeli, Merbau oder Amazaque sieht der Envy auch sehr gut aus. Sie werden Ihre Vorlieben haben. Aber stellen Sie sicher, dass Sie den Platz oben im HiFi-Rack frei haben. Sie werden mit diesem Gerät angeben wollen, und zwar ausgiebig!Der Envy ist jetzt eine neue Kaufempfehlung. Er wurde in unsere Best Gear-Listen mit all unseren Empfehlungen aufgenommen.FELIKS AUDIO ENVY SPEZIFIKATIONENLeistungsröhren: 300BTreiber-Röhren: PsVane CV-181 mk2 (6SN7)2x unsymmetrische RCA-Eingänge (IN1, IN2)1x symmetrischer XLR-Eingang (IN3)Eingangsempfindlichkeit 1V RMSEingangsimpedanz: Für IN1 I IN2 (RCA) 100k?, für IN3 (XLR) 10k?1x Paar Vorverstärkerausgänge als RCA1x Paar Vorverstärkerausgänge als XLRDie maximale Spannung an den oben genannten Ausgängen beträgt 5V (RMS) bei einer Ausgangsimpedanz von 600? und THD<0,5%.Impedanz-Wahlschalterführung: LO – bis zu 60?, MID – bis zu 300?, HI – bis zu 600?-mnhDie Impedanz des Verstärkers: LO bei 32?

This beautifully handcrafted OTL, built around two 6SN7 and two 6AS7G tubes, delivers amazing dynamism, sound stage, and level of details never heard of before in tube amplifiers, at the same time giving that unmistakably tube sound signature. Euforias unique design allows for exceptional sound quality with a broad range of headphones, powerful enough to drive even demanding low-impedance headphones (<32 ohm) including planar magnetics.Crossfeed FeatureCrossfeed is a revolutionary solution in the class of tube amplifiers that provides better control over the listening experience. This is a system that enables more natural channel separation and wider soundstage by moving a part of the lower frequency range to the opposite channel. Listening to a regular headphone amplifier places you “in the middle of the orchestra” – with certain instruments being heard strictly in the left ear while others only in the right one. Depending on the type of music, this can cause discomfort and listener fatigue. Thats why we decided to implement user-switchable cross-feed function among selected products. This lets you try a more natural, less clinical–“front-facing orchestra” experience – like in real life.FeaturesUnrivaled neutrality and soundstageIncredibly detailed and dynamic presentationCrossfeed circuit - a revolutionary solution in tube amplifiersVirtually no background noiseBeautifully hand-craftedPremium driver tubesImproved noise reduction circuitHigh-end class power transformerExtended 3-year warrantyBox contentsBeautifully handcrafted Feliks Audio Euforia EVO Headphone Tube AmplifierMatched pair of driver tubes Psvane CV-181 Mk2 “Gold”Matched pair of power tubes 6N13S (NOS)AC cordUser ManualWarranty CardSpecificationsInput Impedance: 100 kOhmPower Output: 280 mWGain: 20 dBOptimum Headphone Impedance: 32-600 ohmHeadphone Outputs: XLR, 6.3 mmDimensions (DWH): 12.3 x 8 x 7.6 (31.3 × 20.3 × 19.3 cm)Weight: 15.4 lb

Verstärker wurde am 28.10.2023 bei eine deutschen Händler gekauft. Gerät ist fast neu. War nur zum Ausprobieren gedacht. Er blieb viel länger als gedacht, weil er einfach sensationell klingt. Alles Zubehör und die Originale Verpackung ist selbstverständlich vorhanden. Der Neupreis liegt bei ca. 2.500 € Gehört habe ich mit meinen Audio Technica ATH ADX 5000, einem Meze Empyrean, Hifiman 1000 Stealth, T+A P-SE. Mit allen hat er wunderbar funktioniert. Das der Verstärkern mit dem Meze ein Dreamteam bildet, findet man überall im Netz. Was mich wirklich überrascht hat, war die Kombi mit dem T+A P-SE. Der T+A Kopfhörer gefällt mir mit dem Feliks besser als mit dem T+A Verstärker HA 200. Test gibt es sehr viele im Netz. In der Steroplay 12/18 wurde es als Highlight eingestuft. https://www.projekt-akustik.de/mediafiles/Sonstiges/Testberichte/Feliks-Audio/2018-12-Stereoplay-Testbericht-Feliks-Audio-Euforia-Mark-II.pdf Wer ein perfektes Weihnachtsgeschenk sucht um neue Klangwelten zu erkunden, hier ist es.

Neue Webseite unter Audition6Feliks Audio Echo MK2 Referenz Kopfhörerverstärker Dezember 2023Kunden Inzahlungnahme / customer trade-inLagernd, in stock UVP: Euro 899,-- Feliks Audio – Echo MkIIThe new Feliks Audio – Echo MkII is a pure OTL construction tube headphone amplifier with 6N6P tubes. Feliks Audio has increased the power to 380 mW. This will also improve the pairing of lower impedance and some harder-to-drive planar headphones.This headphone amplifier has 3 RCA audio inputs, which are selectable from the front panel, with a new mute function as well. A lot of effort was done by Feliks Audio to have better interference isolation in the amplifier.The Feliks Audio Echo MK2 has a 6.3mm jack headphone output on the front panel and a pre-amp output on the back panel. A refreshed look and Feliks Audio has looked very carefully to make the finish of the amp last longer. It is now more resistant to scratches and fingerprints.Quality build with wooden side panelsThe Echo’s Echo MK2 is made of sturdy solid metal with real wood side panels. The wooden panels along with the tubes give the appearance a hint of retro encased in a timeless minimalistic body. Despite being Feliks Audio’s most affordable model, the Echo looks and feels unquestionably premium.The front panel holds the 6.35mm headphone output and large Alps potentiometer in the center. It has a lovely smooth and weighted action that feels perfectly suited for this robust device.Around the back, the Echo’s rear panel consists simply of RCA IN and OUT connectors, plus the power socket and power switch. The Echo can be used either as a headphone amplifier, preamp, or directly powering active speakers.Based in Poland, Feliks Audio is a relatively new company that specializes in handcrafted tube amplifiers. The Echo is their entry-level tube amplifier for headphones and it uses two 6N6P power tubes and two 6N1P driver tubes.It has an output transformerless topology, which means it will only play well with high impedance headphones. Therefore, Feliks Audio recommends pairing the Echo with headphones that have an impedance of at least 100 ohms.Feliks Audio – Echo MkII Smoother and organic sound qualityThe Echo comes with 2 6N6P power tubes and 2 6N1P driver tubes, which lend credibility to a very slick and silky sound signature. The 6N1P family expressed a very gently warm tonality on the low end, as well as a reserved but plentiful treble.In the case of the Echo, the experience doesn’t quite match. But, that is because of the OTL design. The sonic signature of this family of tubes is more or less being bypassed in exchange for a neutral sound. This is a totally neutral or clinical experience.The Echo imbues the sound with a hint of extra warmth and earthy naturalness. It sounds richer, smoother, and more organic. The bass gains a little fullness and body, but the echo keeps it clean and pristine, preserving texture and definition.Like the bass, the midrange is lush, opulent, and full of nuance and texture. There’s no loss of fidelity or resolution, just a natural warmth that gives the music an inner glow. It reminds me somewhat of the Arcam irDAC-II with its smooth character and rich detail, but it has a more dynamic and lively feel.The Echo adds sweetness to the treble without dumbing it down or losing any detail. Hi-Hats and cymbals sparkle and are rendered with extra air, as if they’re feathered lightly. Note density is left intact and the treble is never left feeling too diffuse or washed out. But some of the edges are taken off, which is perfect for brighter headphones.All this takes place on a blissfully black background. The Echo has been crafted with premium components to keep the noise floor at a minimum, and this is especially noticeable when using sensitive headphones or in-ear monitors. It provides pure, clean power, a touch of warmth, and organic sweetness.Last thought about the Feliks Audio – Echo MkIIIf you are on the lookout for something to elevate your headphone experience and crave a natural, warm, and dynamic sound, we recommend the Feliks Audio Echo highly. It has become an integral part of the desktop setup and won’t be moving anytime soon.All in all, I considered the Echo to be a great starter piece for fledgling audiophiles who are curious about how tube amplifiers sound. It is well-built and it imparts a pleasingly warm and natural tonality to your music that will make you smile as you re-listen to your collection.SpecificationsPower tubes 6N6P x 2, driver tubes 6N1P x 2Frequency response: 15 Hz – 45 kHz +/- 3 dB (300 ohm)Input Impedance: 100 kOhmPower output: 350mWTHD: 0.4 % (300 ohm, 20 mW)Optimal headphones impedance: 100 – 600 ohmPreamp safe modeHeadphones output: Jack 6.3mmRCA audio inputRCA audio output (pre-amp)AC: 230V/120V (power cord included)
