The D1-Six DAC is now the highest end one-box Totaldac DAC. Released in 2016, it inherits from technologies developed for the d1-twelve DAC and the d1-server.
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.
