Ich verkaufe einen Hifi-Kopfhörerverstärker und Digital-Analogwandler O2 + ODAC. Es handelt sich um ein Gerät der Spitzenklasse, welches damals Entwickelt wurde um die objektiv bestmögliche Wiedergabequalität zu erreichen. Kenner wissen Bescheid, alle anderen sollten danach googeln! Es handelt sich um das Kombo-Gerät aus Verstärker und DAC, welches damals mit folgenden Spezifikationen bei HeadnHifi in der Schweiz bestellt wurde: - Back Panel Color: Black - Case Color: Black - Front Panel Color: Black - Volume Knob: Aluminum Black - Gain Settings: Standard (2.5x/6.5x) - Power supply: EU Plug Es handelt sich um das professionell aufgebaute Model (und nicht um die Selbstbauversion). Das Gerät ist in sehr gutem Zustand ohne sichtbare Mängel. Es funktioniert und klingt auch noch wie am ersten Tag. Das Netzteil und das originale USB-Kabel sind ebenfalls im Lieferumfang enthalten. Es handelt sich um einen Privatverkauf ohne Gewährleistung und Rücknahme. Wir sind ein tiefreier Nichtraucherhaushalt.

Used this ODAC for 5 years strong up until a few months ago when I went to plug in the USB jack only to find that its completely detached from the motherboard. Emailed JDS Labs about what happened and they got back to me saying its feasible to repair with some re-soldering & that Im more than welcome to send pictures or send it to them for help. Decided that I could probably do a little soldering job to get it up and running again but clearly I dont know what I was doing when it came to soldering, ended up doing more harm than good and ripped 2 traces off of the where the jack gets seated onto the MoBo. Had no problems with it up until I got involved, so itd likely be good for anyone thats keen on soldering & would like a little side project. That or for the parts. The last picture shows the damage pretty well, but let me know if you have any questions or would like more pictures.
