Douk Audio Amplifier Main Unit Only Review

This Douk Audio listing is an amplifier main unit only, priced at $54.99, 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.

Specifications

How it compares

This listing gives no specifications, so the useful comparisons are price and what each covered model needs. The review's $54.99 is the M4 option, the lowest of the eight; the page opens on the A5 at $72.99. Set against the complete listings, the Douk Audio A5 unit costs $72.99 against $89.99 for the A5 with a 32V/5A supply ($17.00 less), the Douk Audio M1 PRO unit $64.99 against $79.99 with its 32V/5A supply ($15.00 less) and the Douk Audio M4 unit $54.99 against $79.99 with its 24V/4.5A supply ($25.00 less). You then supply your own adapter.

The supply has to match the model. The A5's page lists a working voltage of DC 24-48V, the M1 PRO's DC 19-35V and the M4's DC 12-24V, so a 32V supply that suits the A5 and M1 PRO would exceed the M4's range. Who it suits: owners replacing a failed unit whose adapter still works, or buyers who already hold a matching supply. Anyone starting from scratch saves $15.00 to $25.00 on these three models by buying the unit alone, but must then source a supply.

Shipping, returns and warranty

• Shipping: Douk Audio's current shipping page says orders are generally processed no later than the next business day and arrive in 2-8 business days, with duties, taxes and customs fees included in the checkout price unless noted otherwise.
• Older shipping terms are still online: airmail at 10-25 days for parcels under 2 kg, DHL, UPS or FedEx at 5-8 days above that, and a line saying the store is not responsible for import duties. Check the delivery estimate and any duties at checkout.
• Returns: ask within 30 days of delivery and wait for approval before sending anything; an approved return has to ship within 7 days. Items need all packaging and accessories and no excessive wear, or the store can refuse them or refund part of the price. Refunds go to the original payment method after inspection.
• Not refunded: original and expedited shipping, duties, taxes and customs charges, unless the law requires it or the store made the error. The return page does not say who pays return postage, and the older refund page excludes mistaken orders and change-of-mind returns from free after-sale service.
• Warranty: 24 months from purchase for manufacturing defects, with free repair, a replacement unit and free shipping both ways for covered repairs. Drops, liquid, DIY repairs, lightning, extreme temperatures and misuse are excluded (partial fees may apply), and damage from weak packing on the way back may not be covered. The older refund page still says 1 year.
• Seller: the site is run by Shenzhen Anba Technology Co., Ltd (Shenzhen, China) and HONGKONG LONGSHENG Import and Export Trading Co., Limited (Hong Kong); support is by email at [email protected]. These terms cover orders placed on doukaudio.com; other sellers apply their own.

For this product, the page lists shipping from US, UK, EU, AU and China but shows no Free Shipping, arrival-time, return or warranty badges near the price.
