Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
Sometimes rebranded as the Cello DAC 8.1, the Apogee DA-1000E-20 DAC and power supply are extremely high-quality pieces of kit.

Designed by the famous Dan Lavry at Lavry Engineering. 

The main unit has two digital inputs: Optical Digital (Toslink), and SPDIF Digital Input via BNC connector, otherwise this is a standard RCA type Coaxial Digital Connection.

The only outputs are a pair of balanced male XLR connectors for the left 'A' and Right 'B' Channels.

This particular set is just as good as it gets including its original box, manual, and cables.

SkyFi Cosmetic Notes:
Marks and wear to all covers. Faceplates are in good condition overall.

Brand Background:
Apogee initially made its name with special anti-aliasing filters that solved many of the early problems associated with digital audio. Later, Apogee’s complete conversion systems pushed the envelope of digital audio quality and established Apogee as a key innovator in the field of professional digital audio. Today, Apogee converters and audio interfaces are regarded as the reference standard in the audio industry.

Products such as Symphony I/O, Big Ben, Ensemble and Duet all have set the benchmark by which digital audio recording hardware is judged.

Now with its latest products JAM and MiC, designed especially for Apple’s iPad, iPhone and GarageBand software, Apogee continues to be at the forefront of recording technology. Apogee’s mission is to build products that offer ultimate sound quality, innovative design and unparalleled value to all music creators from the aspiring artist to the discerning audio professional.

Testing Process:
We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect resistors and other passive components for signs of overheating. 

After the visual inspection we connect the DAC's RCA outputs to our Sencore PA81 Power Analyzer which simulates a real world input impedance and allows us to monitor the output on an oscilloscope. We are equipped to test optical, coaxial, and USB inputs at Redbook CD Quality.

We start with a test signal to verify signal lock and proper output on both channels. If the DAC has balanced outputs these are also tested at this time. If the DAC has multiple Optical and Coaxial inputs they are all checked for proper lock. USB inputs are tested with a MacBook Pro. 

After proper function is verified, we setup the DAC for a listening test to evaluate general audio reproduction quality and monitor for clicks, pops, or any other audible signs of issues related to dropped signal lock or failing audio output stages. We often connect the DAC under evaluation to our long term test rig for a long test stint to verify stability under real world operating conditions.
