Nobsound NS-13G Mini 2.0 Channel Digital Amplifier for Home / Desktop Audio, 100W+100W

Our verdict

The NS-13G is a $54.99 wired mini amplifier with a single, clear job: take a stereo RCA signal and drive a pair of passive speakers at up to 100W per channel through dual TPA3116D2 chips. Treble and bass knobs with a bypass give it flexibility, the gray aluminum chassis looks the part, and the 19V supply is included. What you give up is wireless and digital connectivity, plus a full-power rating that assumes a larger 24V supply than the bundled one.

Best for
Desktop and small-room listeners who want a simple, wired mini amp with tone controls and the power supply included.
Skip if
You need Bluetooth, optical inputs or a headphone jack, or you want the full 100W from the bundled supply.

The Nobsound NS-13G is a mini 2.0-channel digital amplifier priced at $54.99, made for home and desktop audio systems at 82 x 108 x 27mm and 260g. It is the wired sibling of Nobsound's Bluetooth amps: instead of wireless inputs, it keeps things simple with a stereo RCA input and banana speaker jacks.

The power section uses two TPA3116D2 chips for a maximum output of 100W+100W, quoted above 24V at 8A into 4 ohm, which Douk Audio says drives the 200W (8 ohm) or 300W (4 ohm) speakers it specifies with no pop or audible noise. The matched speaker window is 3-10 inch, 20-200W at 4-8 ohm. Rated performance includes 18Hz-25kHz frequency range, THD of 0.01% or less, SNR of 98dB or better and 1.1V input sensitivity.

The tone section offers treble and bass knobs spanning plus or minus 10dB, so you can add rousing highs and deep lows, with a bypass function that returns the untouched original sound at a touch. The case is a customized gray aluminum chassis with multi-process fine treatment and CNC precision cutting, while the unique knurling on the volume knob gives it a strong metal feel. A metal DC outlet avoids electric sparks when connecting power.

The NS-13G runs on DC 12V-24V, and the variant options include a 19V/4.74A power supply in the box. One honest caveat: the maximum output figure assumes a larger supply than the bundled 19V unit, so the practical output on the included adapter will be lower than the rated maximum. The package contains the amplifier, the 19V power supply and a manual.

Douk Audio ships worldwide with free and expedited options, and the cost varies by destination country. Packages under 2kg go by airmail (10-25 days); heavier orders ship via DHL, UPS or FedEx (5-8 days). Import duties or customs charges are the buyer'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.
