The totaldac d1-seven DAC has been created for the 7th anniversary of Totaldac. It was made to be the far best sounding one-box DAC in the totaldac range, using the same number of R2R ladders as the d1-six, but with advancements in the analog architecture, the EMC, the firmware and more. This DAC can also integrate the internal server/streamer option for a direct network use. And don’t forget, your d1 as every d1 DACs can be upgraded to a d1-seven!
