SW1X DAC V
SW1X Audio Design™ DAC V Performance Level 5 D to A Converter
DAC V is our forthcoming top of the line, C-core signal output transformer de-coupled version of the DAC IV, 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 is the closest approximation to a truely “invisibly” sounding DAC.
The major benefits of having a signal output transformer (L- inductive 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
Available in different versions: Special and the limited Signature version with different signal output transformer options (Permalloy or Super HiB) and wiring.

We do not recommend purchasing a key system component without first auditioning it carefully, which is why we have demonstration rooms and a flexible home loan policy.
However in certain situations it can be difficult for people to get to our showroom and for those instances we can offer our mail order service.
