SMSL A300 HiFi Power Amplifier BTL Mode Bluetooth 5.0 2.1 Subwoofer 165W x 2 Class D Integrated Amp SDB Sound Effects Hi-Res Digital Audio Receiver with Remote Control THD+N 0.004%

I bought this primarily due to the dedicated subwoofer output with built-in high and low pass filters. It works very well. After use I believe their claims for power output.

I've done direct a/b testing with Fosi v3 mono amp and a Hypex NCore amp which are both very close. The Hypex is comparable but with a slighty fuller midrange but less air on top. However, with two A300 in bridged mode, I found the soundstage clearer and I preferred this over the other amps. In my comparisons a volume setting between 45 and 49 gave equivalent gain to the stand-alone amps. This is a good setting as higher settings increase noise. Under 50 noise is nonexistent to my ears at leastI've always been drawn to amps with clarity, smoothness, and air in the highs and this amp has it. Back in the pre-digital era my amps of choice were j-fet designs and this feels very comparable. However, amps like this really need a good dac. The faults of my Topping E50 and Wiim Ultra dac are very obvious with this amp. In this setup the Mojo2 worked very well.I really didn't need the power of the second amp but it turned out to be a great way to get my dual subwoofers into a 2.2 setup. The subwoofer output and main speaker filtering are very hard to come by if you're not using an AV receiver.And it runs cool to the touch. So, on balance, I've got a nearly 400 w/channel 2.2 setup with wonderful sound for under $400. Amazing.

First off I don't normally write any reviews, in this case just have to say this amp is a great product and think people should know! Won't be disappointed

S.M.S.L.'s A300 class D amp is a little powerhouse. It has really clean sound with super low distortion. I'm using it with a pair of Klipsch tower speakers rated at 100 watts each. The A300 easily pushes them to window-rattling levels.You can customize the sound with various eq presets, there are bass and treble controls as well.The amp has a large digital display with brightness settings. The volume knob turns smoothly with detents. In the back are two analog inputs, a Bluetooth antenna, also USB input, an AC power switch with cable jack, gold plated speaker binding posts and subwoofer out port.It's a great sounding amp for the price of under $200, much more powerful than S.M.S.L.'s AD18 amp.You get a full-function remote and a big display on the amp that can be viewed from across the room.I did have one issue, which is why I'm giving it four stars instead of five:When I first turned the amp on, it was putting out mono sound...Check the amp's menu to be sure it's in stereo mode. The display will read: br1 for mono, br 0 for stereo.The package includes a manual that explains it all, remote and power cable.Recommended!

Got this as a gift for Christmas to pair with a set of Micca MB42X bookshelf speakers. I truly find it hard to imagine you can find a better setup for around $350. I’m really loving this amp. Well built, simple and easy to use, sounds great as well. I’d highly recommend it.

This thing is simply perfect , sounds great, plenty of power, all the features you need. Run it hard all night and you can hold your hand on it, try that with a A-B amp; 3rd degree burns. If you are on the fence, just get it, you will be happy.

Buen equipo cero distorsión y buena potencia lo uso con un DAC IFi audio y suena genial, asegúrate de tener buenos parlantes y subwoofer para tener el rango completo de sonido

El tamaño no importa. Un gran equipo con suficiente potencia para un sala de audición mediana. Estupendo sonido. Aunque su pantalla es un poco decepcionante, eso no opaca la gran calidad de este producto.
