Nobsound NS-01G MAX Amplifier 100W+100W Review

The Nobsound NS-01G MAX is a mini 2.0-channel power amplifier priced at $39.99. It is built around the TPA3221 chip, rated for up to 100W+100W, and is designed to drive 3-8 ohm bookshelf speakers rated between 20 and 120W from a chassis measuring 78x70x23mm.

Wireless and wired input options cover the basics well: Bluetooth 5.0 offers a stable connection at 10-15 meters for phones and tablets, while a 3.5mm AUX input handles CD players, DACs and sound cards. The amp also works as a Bluetooth receiver, which means it can add wireless playback to non-wireless active speakers.

Its PRE OUT adds useful flexibility — a 3.5mm jack output that can feed a powered subwoofer for deep bass in 2.1 channel setups, or connect to audio receivers, amps and active speakers for multi-channel surround systems, upgrading stereo speakers into a theater-like experience. Volume control is smooth and precise, with a real-time dual-color LED indicator, and the circuit includes overheat, overload and short-circuit protection in a durable aluminum alloy case with good heat dissipation.

One power caveat matters: the maximum 100W+100W output is specified under a 24V/8A supply, while the optional bundled 19V adapter delivers an output of 30W+30W. The amp accepts DC 9-24V via a 5.5x2.5mm plug, so higher-voltage supplies raise the ceiling. Also note two connection rules: the PRE OUT does not support headphones, and AUX input has priority — unplug the AUX cable to use Bluetooth.

Specifications

How it compares

At the same $39.99, the Nobsound TONE Mini Bluetooth Stereo Amplifier review lists a TPA3116 rated 50W x 2 into 4 ohms with a 19V adapter in the box, Bluetooth and AUX, banana outputs and no pre-out, in a 78 x 70 x 32mm, 129g case. The NS-01G MAX is the one with a PRE OUT for a powered subwoofer or a second amp. Its page also spells out its power more fully: 30W+30W from its own adapter and 100W+100W only under 24V at 8A, where the TONE page gives a flat 50W x 2 at 4 ohms.

The Nobsound Q10 Bluetooth Amplifier 100W review ($36.99 is its Without Power Supply option, $3.00 less; With Power Supply is $47.99) uses the same TPA3221 chip and a DC 9-24V input and adds an optical input, but its page lists no pre-out and no output figure for its adapter. For speakers above the NS-01G MAX's 20-120W window, the Nobsound NS-15G TPA3116 Amplifier 100W+100W review ($49.99) lists 3-10 inch, 20-200W speakers and a 100W+100W rating above 24V at 8A, with RCA, Bluetooth and tone controls, in a larger 92 x 108 x 30mm case. The NS-01G MAX suits a desk, a sub-assisted 2.1 setup or a small active-speaker rig where size and price matter most.
