Condition: 8/10 The DAC is in real nice condition with only a mark on the top. See pictures.
Functionality: I bought the DAC to satisfy a curiosity and used it for a few weeks together with my Woo WA7 headphone amp. Compared with the internal DAC of the WA7, the Ciunas adds a lot more detail and it sounds more natural. I was impressed! Needless to say, it works as it should (and then some)
Power Supply: Battery Powered (12+ hours of use on a full charge, 2x Lithium Nano Phosphate batteries) Special USB cable is supplied to charge the internal batteries.
Included: Special USB charge cable.
Repair History: None
Tobacco/Pet Free: Yes
Specifications: Size: 78x43x120mm (w x h x d, case) Weight: 420g Two low jitter clocks to handle both speed families Sampling frequencies (kHz):44.1, 48, 88.2, 96, 176.4, 192 Resolution (bits):16 to 24 Inputs:USB 2.0 Type B socket, (2.1mm socket for battery charger power supply) Outputs: single-ended line level on RCA Output voltage: 1.9Vrms SNR: 112dB (A weighted) THD+N: 0.002 (-93dB) @ 1kHz, (@ -1dBFS)
Description: It's a modified I2S Hiface operating at 24/192 integrated with a 24/192 Sabre DAC operates exclusively from 2 internal LiFePo4 (Lithium Nano Phosphate) batteries completely portable - will run for >12 hours from fully charged batteries USB input - standard USB type B input socket RCA analogue outs Outputs standard 2.1V RMS (line level) for driving preamplifier or amplifier Internal battery charger - requires user supplied 5V DC supply Can be charged from the computer using a spare USB port & special USB cable Will drive most headphones directly from RCA ports so is a completely portable, high quality mobile sound system aluminium enclosure
Technical Highlights: The asynchronous USB input handles 24bit 192KHz sampling natively & this signal is communicated via I2S to the 24/192 DAC without any upsampling. The DAC uses one of the legendary ESS Sabre DAC chips with all the proprietary technology of ESS - time domain jitter reduction, Hyperstream architecture The result of this is a very detailed & dynamic sound with fabulous bass reproduction & airy highs. The unbalanced 1.9V analogue outputs are directly DC coupled to the RCA connectors, no capacitors, no low pass filter or active components in the signal path.
Review: AV Revolution: The John Kenny Ciunas DAC, at roughly $750, is a terrific sounding USB DAC that will fit into any space. It features a proprietary battery power scheme that works very well and, to my mind, clearly gives it an edge over similarly priced products.
MSRP $ 650, I am asking $349.99
