d1-six (transistor) DAC or DAC/server Totaldac d1-single front

Compared to the d1-dual, the d1-six uses 6 channels of discrete R2R ladders instead of 4 ladders for the d1-dual.
The transistor output stage is also new for a higher musical performance.
The sound quality is optimum on the XLR output as well as on the headphone jack and on the direct RCA output.
This DAC can integrate the server/streamer board for a direct network use, to listen local files or for streaming use.
All d1 DACs can be upgraded to a d1-six.
