DAC Technology

The technology behind the Swan Song Audio designed DAC module, used in all products, is based on the premise that the manufacturer of the DAC chip produces a quality product.  Problems with producing a good quality DAC are related to poor implementation.  Poor implementation is a result of poor power supplies, poor quality parts, and poor circuit board design.

The DAC module builds on Swan Song Audio’s clean power technology to ensure that the 5 “power supplies” needed to run a DAC do not talk to each other or to the 2 analog power supplies or to the 2 utility power supplies.  In total, 12 Swan Song Audio designed power regulation modules and 4 ground planes are required for proper implementation.

Building a DAC module worthy of being in a Swan Song Audio product requires over 170 parts for the DAC module (this does not include the power supply).  Parts are chosen based on the their ability to exceed the DAC chip’s recommendations and to not infuse the audio signal with any noise or coloration.

Proper design, meticulous implementation, and high quality parts ensure that no matter in what product the DAC module is used, it will the provide the clean music required to allow each Swan Song Audio product to perform at its best.

As with all Swan Song products, all modules and products are designed by Swan Song Audio and built in America.

Class A Headphone Amp / Preamp - $ 2900

Small but mighty, this small amplifier uses a discrete Class A driver to drive headphones ranging from 20 to 600 ohms.  Furthermore, the Class A headphone amplifier saves money by combining the following functions into one package:

  • Preamplifier
  • Headphone amplifier
  • DAC
  • Tone Controls

Three 192 kHz digital inputs are provided to connect the headphone amplifier to a digital source.  For analog signals there is a set of line level analog inputs.  

If there is no headphone plug inserted, the Class A functions as a preamplifier routing the signal to the volume control and the defeatable tone controls.  Once the volume and tonality is set, the signal is sent to the output RCAs.

If a headphone plug is inserted, the signal is fed to discrete Class A circuitry that provides the drive needed for headphones ranging from 20 ohms to 600 ohms.  The Class A design, provides 2 watts of power (into 60 ohms) and tonality that is similar to a tube amplifier.  Simply put, the Class A brings you closer to the music while supporting a broad range of headphones.

Completing the Class A is a beautiful aluminum chassis with solid aluminum knobs.  The wood used for the sides and the lighting color is chosen by the owner.  Wood choices include:

  • Bubinga
  • Curly Maple
  • Mahogany
  • Olive
  • Rosewood
  • Walnut

Why settle for multiple components when you can have a single, beautiful, customizable, component that is designed and made in America?
