JKDAC
Link to new Ciúnas website
The JKDAC has the following characteristics:
- 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.
