Bladelius USB DAC

Swedish Bladelius Design Group's first in a series of mini accessory products is a USB-only DAC.  The Asynchronous USB DAC is 24/192kHz capable (based on the XMOS chip) and is powered by the USB port but signals are galvanically isolated.  It uses a minimum phase type filter with no pre-ringing to achieve a more natural sound with less digital harshness.

• 24 bit/192 kHz
• Asynchronous USB transfer, re-clocking with a fixed low jitter crystal clock
• Galvanic isolation between USB and the analog circuits
• Super low noise power supply with multistage regulation and filtering
• Low order modulator for low out of band noise 
• Digital filter with minimum phase
• Analog output stage is a high performance / high drive (output 2.5v)
