The d1-triunity benefits from the new Totaldac "unity" DAC architecture, with about 290 components upgraded or added to the electronic boards.
The d1-triunity is a d1-unity but with 3 R2R ladders per channel instead of one, giving a lower noise and the real scale of each instrument.
The "unity" architecture allows a better clock distribution, a lower jitter, a lower R2R power supply rail impedance and a lower noise in the digital section.
The R2R ladder resistors are still the famous naked Vishay foil.
The output stage is also fully new, in term of components and in term of schematics, and using discrete components exclusively.
This new output stage produced a 3.5V unbalanced signal and a 7V balanced signal with low impedance for the best versatility, to be connected to all preamps, all integrated amps and also directly to all power amps.
The "unity" architecture gives more presence, more contrast between the timbre of each instrument, more contrast between the size of each instrument, more clarity at the same time as more body and more dynamic, the sound is more realistic and natural giving you more pleasure and no fatigue.
This sound has been adjusted with an analog master tape player as direct comparison and with digital recordings made by Totaldac. Listening tests where made in the new Totaldac auditorium.
The new "unity" architecture still allows all Totaldac d1-x DACs to be upgraded to this new architecture.
