Audio-GD – NFB-11.28 Kopfhörerverstärker mit DAC - DEFEKTSabre ES9028Pro Dac-ChipEingang über USB, coaxial oder optischAusgang über Cinch oder 6,35mm Kopfhörerbuchse (mit ordentlich Leistung auch für hochohmige Kopfhörer!)geliefert wird das Gerät mit Netzstecker Das Gerät wird als DEFEKT angeboten, da es sich seit kurzem einfach abschaltet und dann entweder sofort, nach ein paar Sekunden oder nach leichtem Ruckeln am Netzstecker wieder startet und normal weiterläuft (bis zum nächsten Aussetzer). Ein Wackelkontakt? Für elektronisch versierte Bastler bestimmt interessant!

The venerated and now hard to find NFB-11.28. This is an amazing all in one unit that greatly simplified my desk. Work life is changing, so this unit needs to find a new home. The unit has some marks on it. In some cases the switches are a bit slow to respond, but they do eventually kick over. This unit is wired for 240v, but Im including a high quality grounded step up converter which means that wont be a problem. This includes two power cables and a USB cable (not pictured).

Transform your digital audio into high-quality analog signals with the ADCOM GDA-600 Digital to Analog Converter AUDIO DAC. Designed to deliver superior sound the GDA-600 was manufactured in the United States between 1994 and 1996, and weighs 12 lbs. Unit has been tested and is fully functional. The face is very clean. There are some light scratches to the top (see photos). A power cord is included. GDA-600 The GDA-600 Digital to Analog Converter brings you closer to the reality - and to the astonishing potential - of digital sound by controlling the inherent distortions and design compromises evident in most digital sources. In keeping with a successful begin with the basics approach, Adcoms engineers carefully re-thought the power supply used in this exciting new product. Isolated on its own circuit board, it incorporates a bi-directional AC filter, two transformers, seven separate stages and 27 filter capacitors to increase circuit isolation and minimize noise and unwanted interference. An industry acclaimed Crystal Semiconductor receiver, custom-configured for minimum jitter, forms the front end for conversion circuitry that includes a high speed digital filter and dual selected Burr-Brown 20 bit ladder-type DACs. Each units master clock duty cycle is individually computer-calibrated to insure the highest accuracy. Linear phase anti-imaging filters, 1% metal film resistors and Adcoms proprietary linear gain amplifiers give exceptional analog performance. Again, individual calibration assures minimal DC offset. The GDA-600s flexibility is assured by four impedance-matched inputs: three S/PDIF inputs (two coaxial, one optical) and an AES/EBU XLR input. A buffered S/PDIF output lets you record entirely in the digital domain. Compliance with stringent FCC Rule 15 standards assures minimum RF and EMI emissions and the highest levels of compatibility with other high performance components in an audio-only or an audio/video home entertainment system. The GDA-600 is truly an example of Adcoms forward-thinking engineering where low jitter design, Class A analog circuitry and Adcoms dedication to the highest quality, custom-configured electronic parts combine for a groundbreaking improvement in digital sound.

Audio-gd Headphone DAC R-5.2. see description. Great sounding rca/balanced dac. Started life as a 5.2. Sent back to Kingwa in 2018 to get upgrade to 5.32 and amanero card. The PCB still says 5.2 ISSUE: power button is finicky. May have to press a few times when sitting unused. Price reflects this
