DAC V is our top of the line, super DAC. It is the signal output transformer de-coupled version of the DAC III, powered by Directly Heated Triodes and Directly Heated Diodes. Components & materials inside the DAC V are the finest availble and are harmonically matched to the highest possible degree.
Signal Output Transformer de-coupling of the Valve Output Stage is the closest approximation to a truely “invisibly” sounding DAC.
The major benefits of having a signal output transformer (L- inductive loading & de-coupling) over a resistor-capacitor (RC) signal de-coupling is as following:
Signal output transformers can become invisible components only if the finest core materials, wires and optimum winding techniques are employed – the transparency as well as linearity are improved relative to capacitors, which all tend to mask low level nuances
The dynamics are stepped up because the tube is inductively loaded (one gets all the gain of a tube but at lower DCR) unlike with a high value resistor (which lessens dynamics)
The output impedance of a tube output stage is lowered (stepped down, squared root of the ratio), which gives a better drive to the consecutive amplification stage. This in turn provides a more convincing dynamic realism
Available in different versions: Special and the limited Signature version with different signal output transformer options (Permalloy or Super HiB) and wiring.
