OPPO HA-1 Sym. Class-A Kopfhörerverstärker/ Vorverstärker/ PreAmp/ DAC in silber Baujahr 2015 gebraucht und mit Gebrauchsspuren (siehe Bilder) in OVP. Nachdem ich das Gerät nur noch selten nutze, habe ich mich dazu entschlossen, den OPPO HA 1 zu verkaufen. Ich bin Zweitbesitzer und habe das Gerät bereits seit 2016 im Besitz. Wenn Sie sich für das Gerät interessieren, werden Sie wissen, dass sich Oppo vor einigen Jahren vom HIFI - Markt zurückgezogen hat und seitdem keine Geräte mehr gebaut werden.Das ist sehr schade, gerade wenn man dieses technische Schmuckstück als Maßstab nimmt. Die Fachpresse hat sich damals vor Begeisterung geradezu überschlagen - das muss man nicht immer Ernst nehmen, aber der Materialaufwand den die Chinesen hier betrieben haben, führte zu einem wirklich überagenden Ergebnis als Kopfhörerverstärker und DAC. Als Vorverstärker ist das Gerät meiner Meinung nach weniger geeignet, da die Ausgangsspannung doch nicht ganz praxisgerecht ist und ein sehr leises Signal an der Endstufe ankommt.Sollte(n) Ihre Endstufe(n) damit gut zurechtkommen, dann könnte das auch passen, bei mir war das nicht der Fall, daher habe ich den Analogausgang auf festen Pegel gestellt und das Gerät am Vollverstärker/Vorverstärker angeschlossen. Es gibt eine schicke Fernbedienung, worüber sich Eingang und Lautstärke regeln lassen. Einige Grundeinstellungen lassen sich nur am Gerät selbst einstellen (z.B. Displaygestaltung: VU-Meter/Spectrum/Display aus... - Ausgang fix oder variabel s.o.). Es gibt eine Vielzahl an digitalen Eingängen (siehe Bilder: Coax/Opt./Aes-Ebu/Usb B/I-Pod auf der Front). Analog stehen jeweils 1x RCA und XLR-Ein- und Ausgänge zur Verfügung.Kopfhörerausgänge sind als 6,3 Klinke und 4 Pol.Balanced vorhanden. Der Preis scheint mir, nach Marktanalyse, angemessen. Preisvorschlag kann genutzt werden, aber ich werde nur auf seriöse Angebote eingehen. Zu den Versandkosten: Es beinhaltet eine Transportversicherung, damit Sie und ich nicht bei Verlust des Gerätes finanziellen Schaden nehmen. Gerne können Sie das Gerät auch in Dortmund abholen und sich vom Zustand und der Funktion überzeugen. Fragen werden gerne beantwortet, soweit mir das möglich ist. Nutzen Sie auch das www. ! Privatverkauf: Keine Rücknahme - Keine Garantie oder Gewährleistung. Vielen Dank für Ihre Aufmerksamkeit.

Comes with remote and power cord. Will be insured to the full purchase price and mailed with UPSs Pack and Ship guarantee against loss or damage. No returns. Audio equipment is subjective -- I think this amp sounds great, but maybe youd like the sound of a different one more. Im not a retailer or even a small business; Im just an audio enthusiast, like you. So, I cant afford my auctions to be used to audition equipment. Please only buy this amp with that in mind. (But, for what its worth, I personally love the sound from these Oppo amp/DACs and wish they werent discontinued) Thank you.

A Class A amplifier conducts signal over the entire range of the input signal cycle. The output transistors are biased to operate in their most linear range, and there is no crossover distortion caused by switching the signal between two push-pull devices. The HA-1s power amplification circuit for the headphones is Class A built with discrete transistors. The discrete design allows us to hand-pick and match the best parts to build the HA-1.
