THE DAC 25A is considered a reference product in its class. Its aim is to conquer the new audio formats market. It is considered a best buy and in Japan it was an absolute successes.

Digital Analog Converter + Headphone Amp – DAC 25A
Made to convert your music files into an analogue signal. Its features are superb, the conversion is handled by a Burr Brown 1792, that transformers the signal into a balanced analogue output. Pride of Onix.

Front: Black Glass. Front handle that controls the headphone’s volume. Golden buttons that are displayed ergonomically. SELECT button to choose the input and a SRC button to select the sampling rate.

All components are carefully selected and carefully placed on the circuit board for both digital and analogue components. R-CORE transformer and Nichicon “Gold Tune” series capacitors.

CD PLAYER CONVERTER: The signal is taken after the mechanical stage and can be used an excellent replacement to an old converter. This can be done with the Digital or RCA outputs.

MULTIMEDIA CONVERTER: From music stored in a Hard Disk. Using a computer or a multimedia center. This can be done with the USB port.

AMPLIFIER FOR HEADPHONES: Excellent sonic qualities, the sound can be from an external CD player or computer. The DAC has a volume control knob.

Brand Background:

One single owner since new.

Inputs: Digital optical (S-PDIF) ,RCA Inputs and a USB Port to select music from a PC or Mac.
Outputs: RCA (L+R) ,balanced XLR (L+R). High Quality connectors Filtered Power supply. Native analogue balanced circuitry.

The SkyFi 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 set the DAC up 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 DACs under evaluation to our long term test rig for a long test stint to verify stability under real world operating conditions.

Dynamic range: (24bit)> 120dB; Signal to Noise Ratio:> 112dB (RCA);> 125dB (XLR); THD + N: <0.001% (20Hz-20KHz); Output XLR: 4.0V; Output RCA: 2.0V; Power supply: 220-240V.
