Review: Great Amplifier for the price. - Amazing little amplifier which I bought for my sister (she wanted speakers like mine because I got an SMSL SA-50) , it's definitely not as good as my SMSL SA-50, but for the price it is plenty loud and has decent quality. For the price it's the best you can get, it's tiny, comes with everything you need and works pretty much instantly. it has AUX audio input, with two cables provided, a decent quality 3.5mm male to 3.5mm male audio cable and a 3.5mm to RCA cable, both are excellent quality (the RCA to 3.5mm was so good I actually used it to replace my old cable which often had issues). It also has a USB audio input and a USB cable to allow you to connect it to your pc (probably phone too if you have a USB OTG cable), this allows you to use your Nobsound as an external USB DAC (Digital to analogue converter) and then uses the output from the DAC for the amplifier. Lastly it has Bluetooth input, this is convenient as it allows you to use the amplifier wirelessly, I believe the Bluetooth connection has been updated from the previous model of the Nobsound to Bluetooth 4.0 allowing for higher quality transfer of audio, however there is still an audible difference in sound quality as music sounds worse on Bluetooth - try not to use the Bluetooth when possible. The device does come with a power brick and UK power plug, I've had no issues with these and they do the job perfectly. The audio quality is good, but not amazing, if you want quality go for something a little more expensive such as the SMSL SA-50 which can achieve much better quality at louder volumes, however if you're tight for space or money, you can't go wrong with this device. There is no way to switch between the inputs, you physically connect and disconnect each cable and a voice will speak whichever input is being used, its simple but it works. I'd 100% recommend this Amplifier, but if you want quality over connection options, go for the SMSL SA-5 or even the SA-36.
Review: Awesome little amps with built-in soundcard - used for running bass shakers on my Sim Rig. - I've had one of these for years hooked up to a pair of JBL Control Ones, and the sound is impressive. I usually connect to my phone using Bluetooth, and it always amuses me to hear the voice say, "Bluetooth Mode" when I turn the amp on, because it sounds just like Mary Poppins! In all the time I've had that amp, I never knew that it also has a built-in soundcard. If you plug it into a PC (I'm on Windows 10), it's detected as a USB sound device, and can be assigned audio just like any other soundcard. That is a massive bonus, as it means I can use it to drive a pair of bass shakers using software connected to a driving or flight simulator program without needing to mess about with additional soundcards. I've just bought a second, identical one and have now got the two of them hooked up to four Puck bass shakers. They vibrate my simulator rig stand to give a more realistic sensation, and to give feedback about how the car is behaving on track. I can also connect the amp to my PC through the Bluetooth dongle, and again, it's seen as an audio device. However, I wasn't able to get two of these amps to connect to Bluetooth at once, so my sim rig will be connected via USB. With just one connected, it did run the bass shakers over Bluetooth. My old amp has been out in my workshop, frozen in the winter, baked in the summer and has been totally reliable, and in all honesty it's far louder than I really needed in a shed / garden workshop. The amp comes with a 12V power supply (with a proper UK moulded plug). This type of amp can produce more output power with more voltage, up to 50W per channel at 24V. With the 12V supply the amp is completely unstressed. Just to see what it was capable of, I hooked it up to my PA speakers - a pair of huge boxes housing passive 12" drivers and compression-driver horns, rated to 400W. The amp didn't care! It ran them perfectly happily and was surprisingly loud with the 12V power supply. It's definitely enough for the Puck bass shakers, which are only rated at 15W. Also in the box is a USB cable, a stereo 35.mm jack to jack cable and a stereo phone to 3.5mm jack cable. These amps are very hard to beat for the price if you want a something with a small footprint that can run pretty much any speaker you give it. They have proper binding posts for the speaker outputs and both Bluetooth and USB connectivity. There is also an AUX-IN socket so you can connect older sources.
