Used Topping PRE90 preamp. The preamp is in excellent working condition and sounds great. There are numerous reviews on line. The one complaint is the remote has to be aimed at an angle from the bottom or side for it to work well. The online reviews say the same thing. Other than that this is a great little preamp.

Es ist ein ausgezeichneter Partner für den Decoder TOPPING D90. MerkmaleHochleistungs-NFCA-ModuleA90 implementierte das erste Mitglied der neuen NFCA-Modulserie (Nested FeedbackComposite Amplifier) der Spannungs-Strom-Hybrid-Feedback-Architektur zusammen mit der UHGF-Technologie (Ultra High Gain Feedback) für eine hervorragende DC- und AC-Leistung. Die hohe Ausgangsstrom-Antriebsfähigkeit ermöglicht es dem Verstärker, Kopfhörer mit niedriger Impedanz mühelos anzutreiben. Ultra Low Noise von 0,2 uV ist der Konkurrenz meilenweit voraus und bietet einen absurd hohen Dynamikbereich von 145 dB und kein hörbares Rauschen und den dunkelsten Hintergrund für die empfindlichsten IEMs.Vollständig symmetrischer + SE-KopfhörerausgangDer A90 verfügt über drei Kopfhörerausgangsbuchsen mit 4-PIN-XLR, 4,4 symmetrisch und 6,35 SE, um verschiedenen Verwendungszwecken gerecht zu werden.Die SE 25Vpp symmetrische 49Vpp hohe Ausgangsspannung zusammen mit einem hohen Ausgangsstrom und einer Ausgangsimpedanz von weniger als 0,1 Ohm, A90 ist mit einer breiten Palette von Anpassungsmöglichkeiten an Kopfhörer ausgestattet.A90 ist mit drei Verstärkungseinstellungen von -9,5 dB / 0 dB / 9,5 dB für SE und -3,5 dB / 6,0 dB / 15,5 dB für symmetrisch ausgestattet. Durch das Rauschen von nur 0,2 uVrms passt sich der A90 problemlos an alle Arten von Kopfhörern an, von extrem empfindlichen IEMS bis hin zu den meisten leistungsfordernden Over-Ears in voller Größe.Die NFCA-Module des A90 können nicht nur diesen Kopfhörer ansteuern, sondern auch als Vorverstärker dienen. Im Vorverstärkermodus sind die 20-Ohm-SE- und 40-Ohm-symmetrische Ausgangsimpedanz für verschiedene Leistungsverstärker geeignet. Lieferumfang und Zubehör wie in den Fotos abgebildet / Items and accessories included as shown in the pictures.

Two ES9039SPRO chips - Each of the left and right audio channels independently utilizes an ES9039SPRO, providing higher SNR (135dB) , greater dynamic range, and lower distortion (<0.000045% THD+N) compared to the D90SE. Clearer details flow into your ears. Advanced CPLD processing - We achieved incredible jitter rejection using CPLD to process the clock signal and optimize the digital signal.Regardless of USB, optical, coaxial, AES input, jitter is as low as -160dB. Brand new I/V conversion - A brand new I/V conversion circuit is designed for better quality audio reproduction. The new circuit design provides lower distortion and lower noise while occupying less space. The new circuit is pushed close to the limit of physics so that we are able to squeeze out the last bit of performance of the DAC chip. LDAC wireless available - D90 III SABRE is equipped with QCC5125 and Bluetooth 5.1, supports LDAC/aptX-Adaptive/aptX-HD/AAC/SBC. It can support up to 96kHz/24bit, so that high-quality audio can be transmitted wirelessly to obtain music experience beyond CD level. Universal compatibility and ease of use - The D90 III is a breeze to use with its wide compatibility range. It supports various operating systems like Windows, Mac, Linux, and iOS/Android. For Windows ASIO, a simple driver setup is all it takes. The device's USB hardware is based on XMOS XU316 and Thesycon drivers, ensuring stability and reliability.

Comes with all original pieces. Used for about 6 months.

· Vollsymmetrische Verstärker Architektur für vollen Genuss. Klassische Stereo Chinch Eingänge werden selbstverständlich ebenso unterstützt. · Pre90 nimmt eine vollständig ausgewogene Struktur an. Der Ausgang kann ausgeglichen, single- endend, symmetrisch + einseitig sein. · Mit symmetrischem + einseitigem Zwei-Wege-Eingang, zusätzlich zur normalen Vorverstärker-Nutzung · Pre90 kann für die Signalumwandlung symmetrisch zu sin- gle- end oder Single -End to Balanced verwendet werden. · Mit Hilfe der maximalen Verstärkung +16 dB könnte Pre90 das schwache Eingangssignal leicht auf akzeptable Stufe des nächsten Verstärkers verstärken. · Es ist erwähnenswert, dass, da das Rauschen so niedrig wie 0,3 uVrms ist, dieser Schritt kein hörbares Rauschen erzeugt, während das Signal verstärkt wird. · Der Topping EXT90 ist das Gerät, das die Funktionen des PRE90 vervollständigt und ergänzt und es ermöglicht, weitere Eingänge zu diesem hinzuzufügen.· Kombinieren Sie EXT90 und PRE90 und erhalten Sie zwei unsymmetrische Cinch-Eingänge und vier symmetrische XLR-Eingänge. · Perfekt zum Erstellen eines Audiosystems mit mehreren Quellen.
