USB DAC
Digital has never sounded this analog





This is the first in a series of small accessory products that we are planning to add to the Bladelius product line. This is just not just another new USB DAC we have but a lot of effort has been done to make the USB DAC as analog in its performance as possible. Therefore we chose to use a digital filter of minimum phase type instead of the the more common linear phase type witch always gives pre-ringing (see picture 3) We use a slightly alter version of minimum phase to even further improve the performance.

Our goal has been to really include everything that is possible to get the best sound from your computer.

Technical specifications
Accepts data up to 24 bit/192 kHz
USB powered
Asynchronous USB transfer, re-clocking with a fixed low jitter crystal clock
Galvanic isolation between USB and the analog circuits, that means no noise from the computer will be transferred to you amplifier
Super low noise power supply with multistage regulation and filtering
For low out of band noise we use low order modulator
For a more "analog" behavior (no pre-ringing) we use a digital filter with minimum phase
The analog output stage is a high performance stage with high drive capability
