SW1X DAC V Signature

The DAC V Signature is an all-out, no holds barred assault on the pinnacle of the art and then some. It is the finest piece of equipment we have had the pleasure to audition. It redefines any parameter you may care to mention such as micro dynamics, ease of presentation, transparency, fine resolution etc. It transcends all of these and leaves the listener spellbound. 

The DAC V is a signal output transformer de-coupled DAC powered by Directly Heated Triodes and Directly Heated Diodes. Components & materials inside the DAC V are the finest available 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:

1. 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
2. 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).
3. 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

The DAC V is available in different versions: Standard, Special, the limited Signature version with different signal output transformer options (Permalloy or Super HiB) and wiring. The Signature version includes Pure Silver Wound Output Transformers.
