Douk Audio Amplifier Main Unit Only (Power Supply Not Included)

Our verdict

This listing sells the amplifier main unit only - the DC power supply is not in the box. It covers eight Douk Audio and Nobsound models (A5, A5 PRO, ST-01 PRO, NS-13G MAX, M1 PRO, M4, NS-14G and NS-14G PRO), each selectable with US, UK, EU, AU or China region variants. It is the right buy if your amplifier unit failed but its adapter is fine, or if you already have a matching power supply. Because the page publishes no specs for the individual models, confirm your model and power requirements before ordering.

Best for
Owners of a Douk Audio or Nobsound amp who need a replacement main unit and already have a compatible power supply.
Skip if
You need a complete amplifier with a power supply, or you need published specs to choose a model - this listing includes neither.

This Douk Audio listing is an amplifier main unit only, priced at $72.99, with the power supply explicitly not included. It exists for buyers who need the amplifier unit itself - for example as a replacement if an existing unit has failed while its adapter still works, or when a suitable power supply is already on hand.

One price covers eight different models, selected at checkout: the A5, A5 PRO, ST-01 PRO, NS-13G MAX, M1 PRO, M4, NS-14G and NS-14G PRO. Each is available in US, UK, EU, AU or China variants, so pick both the model and the region that matches your setup. Douk Audio publishes no further technical details on this listing - no power ratings, input or output specs for the individual amplifiers - so this is a listing to order against your own knowledge of the model you own, not one to choose a system from.

If you are replacing a unit, match the model exactly and remember you will need the correct DC power supply for it, since none is included. If you are unsure which model you need or what power supply your system requires, it is worth contacting the store before ordering.

Douk Audio ships worldwide with free and expedited options; costs vary by country. Parcels under 2kg ship airmail (10-25 days), heavier orders by DHL, UPS or FedEx (5-8 days), and any import duties or customs fees are the customer's responsibility. The store offers a 30-day free return or full refund and a 1-year warranty on all items, excluding orders placed by mistake, man-made damage or misuse, subjective change of mind, and anything outside the warranty terms.

What we liked

  • Lets you buy just the amplifier main unit instead of a complete amp and adapter set
  • Covers eight different Douk Audio and Nobsound models, from the A5 through the NS-14G PRO
  • Region-specific variants let you match your power market at checkout

Worth noting

  • The power supply is explicitly not included, so you must already own a compatible adapter or buy one separately
  • Almost no technical specifications are published on this listing - check your amplifier's requirements before ordering
  • With eight models under one price, ordering the wrong model or region variant is easy if you do not check first
