Neue Webseite unter Audition6Benchmark Media DAC3 HGC Referenz Stereo DAC + Vorverstärker (auch analoge Eingänge) + KopfhörerverstärkerModell Frühjahr 2024 UVP: Euro 2890,-- Zum Verkauf kommt ein nagelneuer Benchmark Media DAC3 HGC Referenz Stereo DAC + Vorverstärker + Kopfhörerverstärker des amerikanischen Spezialisten.Wird nach Kauf beim deutschen Vertrieb geordert, will be ordered after purchase.Evtl. etwas Lieferzeit einplanen. Maybe some waiting time.Einmalige Chance!Näheres finden Sie auf der Webseite des Herstellers!Benchmark Media DAC3 HGCDer DAC 3 ist ein kleines Gerät, das vollständig die Funktionen eines Vorverstärkers (auch mit analogen Eingängen), Digital-Analog-Wandlers und Kopfhörerverstärker vereint - in Studioqualität.Zusammen mit dem passenden Endverstärker AHB2 hat man schon eine in Abmessungen kleine Highend-Anlage. Ausführung in Silber oder Schwarz. Es ist zusätzlich eine schwarze Fernbedienung (Remote) erhältlich. Technik des Benchmark DAC3Verringerung harmonische VerzerrungenHybride LautstärkeregelungUltraLock3™ Jitter VerringerungHigh-Headroom DSPMulti-Mode Asynchronous USB Audio SystemQuad 32-bit Symmetrischer D/A WandlerVerteilte Netzteil-RegelungenVerringerung harmonischer VerzerrungenDer verwendete ES9028PRO hat zwei unabhängige Systeme zur Verringerung harmonischer Verzerrungen, die fast vollständig die Verzerrungen der zweiten und dritten Oberwelle erreichen. Der Benchmark hat zudem ultra-saubere analoge Ausgangsstufen. Nach aktuellem Stand gibt es keinen anderen DAC mit niedrigeren THD Verzerrungen als der DAC3.HGC = Hybrid Gain ControlHGC ist Benchmarks einzigartiges Hybrid Gain Control system. Der DAC3 kombiniert eine aktive Verstärkungsregelung, ein passives Widerstandsnetzwerk, eine 32-bit digitale Verstärkungsregelung und eine fernbedienbare motorbetriebene Lautstärkeregelung. Die analogen Eingänge werden nicht digitalisiert und digitale Eigänge gehen nicht über eine analoge Lautstärkeregelung Digitaleingänge werden über ein 32 Bit DSP System gesteuert. Das DSP gewährleistet präzise L/R Balance, und eine präzise Stereo Abbildung,Das passive Widerstandsnetzwerk erlaubt verzerrungsfreie Verstärkungsregelung ohne die Dynamik zu begrenzenr. Widerstände optimieren die Verstärkungsfaktoren der Stufen zwischen dem DAC3 und dem Endverstärker. Diese Optimierung ist entscheidend für die erreichbare Gesamtqualität der Kette.UltraLock3™ Jitter Attenuation SystemUltraLock3™ erreicht die Phasengenauigkeit innerhalb von nur 6 ms. DSP Verarbeitung mit 32 bit, ein DSP Headroom von 3,5 dB, Eine sample rate von 211 kHz, und Jitter-bedingte Verzerrungen 140 dB unterhalb des Musiksignals - einfach nicht hörbar.High Headroom DSP - mit 3.5 dB Zusatz Digital HeadroomDie digitale Signalverarbeitung erlaubt eine Verarbeitung der Signale bis +3.5 dBFS. Die meisten Digitalprozessoren clippen Signale oberhalb von 0 dBFS. Die 0 dBFS Grenze scheimt hinreichend, da 0 dBFS das höchste Sinussignallevel im Signalprozessor ist .Eine genaue Untersuchung hat ergeben, dass in PCM-Systemen inter-sample peaks Werte von leicht über +3 dBFS erreichen können, auch wenn die einzelnen Abtastwerte niemals 0 dBFS überschreiten.Diese inter-sample overs sind allgemein häufig auf kommerziellen Aufnahmen zu finden, sind aber erst dann von Bedeutung, wenn ein Interpolationsprozess beginnt. Aber fast alle DACs nutzen aus verschiedensten Gründen Interpolationsprozesse.Inter-sample overs führen in den meisten Wandlern zum clipping. Das clipping erzeugt disharmonische, unmusikalische Verzerrungskomponenten. Benchmark gibt an , dass diese Verzerrungen eine harsche Wiedergabe oder unnatürlichen Hochtöne erzeugen. Durch den zusätzlichen 3,5 dB headroom werden diese Verzerrungen vermieden. Benchmark sieht darin einen großen klanglichen Fortschritt.Multi-Mode Asynchronous USB SystemBenchmarks USB system unterstützt USB Audio 2.0, DSD, and USB Audio 1.1. Der DAC3 hat eine Master Clock mit geringem Jitter. Der Computer tranferiert Daten im asynchronen Modus zum Buffer des DAC. Der Inhalt des Buffer wird dann widerum asynchron zum D/A System übertragen. diese zweite asynchrone Übertragung eliminiert alle Spuren von Jitter Keine Spuren von Jitterbedingten Verzerrungen sind mit der aktuellen Messtechnik messbar (besser als -150 dBFS). Das ist State of the Art.Keine Treiber sind für MAC OS erforderlich, lediglich für 192 kHz and DSD muss ein Windows Treiber installiert werden. USB Audio 1.1 mode unterstützt Bitraten bis 96 kHz. Dieser USB mode kann gewählt werden, damit ist ein plug and play mit allen Betriebssystemen möglich.Quad 32-bit Symmetrisches Conversion SystemVier symmetrische 32-bit D/AWandler ergeben eine Wandlung von Strom zu Spannung mit niedriger Impedanz. Die 4:1 Redundanz verringert auch das Rauschen und die Verzerrungen. Durch die 4:1 Addition erreicht der DAC3 eine Verbesserung um 6 dB von Signal-Rausch-Abstand und THD.Phasen - SchalterAufnahmen mit verkehrter Phase können invertiert geschaltet werden.Home Theater BypassDer DAC3 kann in ein Heimkino integriert werden, dafür hatt er eine Durchschleif-FunktionDigital Pass ThroughDer zweite Coax-Eingang kann auch als digitaler Ausgang konfiguriert werden.Bi-Directional 12 Volt TriggerDer Trigger-Anschluß kann zum automatischen Ein/Aus von Geräten genutzt werden.NetzschalterDer Netzschalter schaltet in Standby oder Total-Aus. Auch im Total-Aus reagiert er noch auf Trigger oder Fernbedienung, der Stromverbrauch ist dann niedriger als 0,5 WNiedriger StromverbrauchDer DAC3 verbraucht im Betrieb nur 12 W .HPA2™ Kopfhörerverstärker auf ReferenzniveauDer DAC 3 hat zwei Kopfhöreranschlüsse und einen Verstärker mit hoher Stromlieferfähigkeit und 0-Ohm Impedanz.

The DAC2 converter has lower noise and lower distortion than Benchmarks DAC1 converter.The performance of the DAC2 exceeds the measurement limits of some of todays best test equipment. The DAC2 delivers outstanding musical detail and precise stereo imaging. It employs an advanced high-headroom digital filter design, and a new high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmarks new UltraLock2™ jitter attenuation system. Internal digital processing and conversion is 32-bits, and this processing includes 3.5 dB of headroom above 0 dBFS. This headroom prevents the DSP overloads that commonly occur in other D/A converters. Four balanced 32-bit D/A converter are summed together to create each balanced analog output. This 4:1 summation provides a 6 dB noise reduction, and gives the DAC2 industry-leading performance. Native DSD Conversion All digital inputs on the DAC2 support native PCM or DSD conversion. From any input, DSD is transported with bit accuracy over DoP 1.1. DSD and PCM are both natively converted to analog. There are no DSD to PCM or PCM to DSD conversions to compromise the quality of the music. The DAC2 conversion system seamlessly switches between native PCM and native DSD conversion. DSD over DoP 1.1 is supported by many media players, and DSD downloads are now available from several sources. Direct Connectivity to Power Amplifiers Benchmark DAC1 and DAC2 converters are designed to directly drive power amplifiers and speakers. Benchmark converters feature adjustable low-impedance passive attenuators at the XLR outputs that can be used to optimize the interface to the power amplifier (or powered monitor). This unique Benchmark feature optimizes the gain staging between the DAC and the power amplifier. Proper gain staging cannot be overemphasised. When audio stages are properly matched, each component in the audio chain is able to operate at its optimum signal level, and the system performance is significantly improved. Sonically-Neutral Studio Monitoring All Benchmark converters are designed for maximum transparency. This transparency is absolutely essential in the studio monitoring chain. For this reason, DAC2 converters are ideal for critical reference-quality professional systems. Unlike many competing products, the DAC2 is not designed to add euphonic coloration to the audio. Instead it is designed to be as uncolored and natural as possible.

Benchmark DAC 1 Pre combination pre amp headphone amp and 24 bit 192 khz digital to analog converter. Please note the USB input is limited to 24bit 96khz. Features fixed or variable analog unbalanced RCA and balanced XLR outputs as well as two 1/4 inch headphone jacks. Inputs include USB 2.0, optical toslink, 3 coaxial digital, and one pair of analog stereo RCA connectors. The front volume control is a fully analog high quality Alps brand. The headphones outputs are always variable while the rear balanced XLR and unbalance RCA outputs are selectable as fixed or variable. The versatility of the Benchmark is truly great. I used it in both a headphone setup and in my main home stereo system with excellent results. This is a Stereophile Class A recommend component as are each of its offspring. It offers a highly detailed and layered sound that competes well above its price point. Of all the Benchmark DAC 1 options. The PRE and HDR offer the most versatility and were the last versions of the DAC1 before being replaced by the DAC2. The HDR simply offers a remote control which the PRE does not. This unit is in excellent condition overall with no scratches or dings anywhere on it. The only thing I see that keeps it from being mint is the n in the analog input lettering is partially missing (see photos). Everything functions as it should and it sounds excellent. The original power cord is included. There is no documentation or original packaging but it will be securely packaged for shipping. I will accept offers above my initial listing price if you wish to purchase this before any bids are placed. Once a bid is placed this option will disappear. Please check my feedback and purchase with confidence. Thank you for your interest.

NOT USB MODELThis is the model without rack ears. Includes original box. paperwork/manual, power cord and BNC/RCA adapter.Benchmark DAC1The DAC1 is a reference-quality, 2-channel 192-kHz 24-bit audio digital-to-analog converter featuring Benchmark’s UltraLock™ technology. The DAC1 is designed for maximum transparency and is well suited for critical playback in studio control rooms and in mastering rooms. A compact and rugged enclosure makes the DAC1 an excellent choice for location recording, broadcast facilities, and mobile trucks.Made in the USABenchmark products are designed and manufactured in the USA.An Industry StandardBenchmarks award-winning DAC1 has become a standard in the finest recording studios and mastering rooms. Audio engineers rely of the accurate, uncolored, and precise sound of Benchmark DAC1 converters. The DAC1 is free from digital artifacts and its analog sound eliminates the fatigue that is caused by many digital devices. Audiophiles have also discovered the smooth and detailed sound of the DAC1, and it has become a centerpiece in may home listening rooms.International Power SupplyThe large internal power supply supports all international voltages and has generous margins for over and under voltage conditions. The power supply is sized to supply the demands of the HPA2™ headphone power amplifier when driving two sets of headphones.Calibrated or Variable Output LevelsThe front-panel gain control sets the output level of the headphone jacks. It can also be used to control the output level of the balanced XLR and unbalanced RCA analog outputs. A rear-panel switch selects Variable or Calibrated output levels. In the Calibrated setting, the rear-panel outputs are controlled by multi-turn calibration pots.Direct Interface to Power AmplifiersAll Benchmark DAC1 and DAC2 converters are designed to directly interface with power amplifiers and powered monitors. The XLR outputs are equipped with Benchmarks exclusive low-impedance passive output attenuators. These attenuators can be set in 10 dB steps to optimize the gain-staging between the DAC and the power amplifier. This important feature maximizes the signal to noise ratio of the entire playback system.Jitter-Immune UltraLock™Digital interconnect cables, electro-magnetic interference, and many other variables introduce jitter into the digital audio. Jitter presents a major problem to most D-to-A converters. Jitter is a type of clock error that, if not properly addressed, can cause the D-to-A to misfire. The result of these misfires is a non-musical, digital distortion.Many modern (and expensive) converters suffer from severe jitter-induced distortion. Jitter is NOT a problem for the DAC1, which achieves jitter immunity by utilizing Benchmarks proprietary UltraLock™ clock-recovery system.With the UltraLock™ clock-recovery system, the digital-to-analog conversion-clock in the DAC1 is totally isolated from the clock of the digital audio input. This clock-recovery topology outperforms even the most well-designed two-stage PLL designs. Using state-of-the-art Audio Precision testing equipment, no jitter-induced artifacts can be detected with the DAC1. Any signal that can be decoded by the AES/EBU receivers will be reproduced without the addition of any measurable jitter artifacts. The bottom line is this: Benchmark converters will consistently and faithfully deliver truthful audio with no jitter-induced artifacts, no matter what variables are present.
