Review: Good Sound, Great Price, What more could you ask for? - Right now, I'm listening to a jazz album and the first thing that struck me was how clear the midrange is from this little amp, the mids just sparkles with musicality, the bass is solid, but not overbearing, and the highs are smooth and clear. All this hit me within the first three minutes of listening to my new album And all this for less than £50.00 makes this Nobsound NS-20G amp the bargain of the century. Still, it must be remembered that this great little amp is dependant on the speakers you are going to use with it. Although this is a brilliant product I have one small(ish) gripe, the on/off volume knob will continue to turn, either forwards or backwards, with no stopping or starting point (I could find), though there are small clicks that can be heard and felt when the knob is turned. Still you can tell the volume levels, before you start your music, by the white L.E.D indicator on the front of the amp. IMO, a £50.00 punt on buying this amp is well worth doing because when you win you win big. Therefore, I heartily recommended this amp to the music enthusiast that does not want to spend a fortune, or take out a second mortgage, just to enjoy his or her music collection. BTW, I have just listened to one album so far, and I am blown away by the sound, but if I change my mind I will be back to update my review but so far this is a 5 star product for it's sound quality and bargain price. PS. I've listened to some more of my albums and I have not changed my opinion about this great little amp, plus it has good stereo separation as well. The second one of these great little amps arrived today, 14/01/2020, and after getting it working with my music system, I am just blown away. The mid-range is clearer, the bass is firmer and the highs sparkle a bit more without getting fatiguing. Mind you, I am running two of these amps simultaneously and it's just great. Double 5 stars. This is my third NS-20G mini-amp, this one received on 15th Jan 2022, and my opinion has not changed, it's still a five star product and great device. However, my only concern is the PSU that comes with the mini-amp, if pushed by playing the amp at loud volumes the PSU will fail and so what I tend to do is replace it asap with a laptop PSU.
Review: Sounds excellent - outstanding value. - OK, first wow. Really this is a genuine bargin at £50. I have just fitted insulation to my conservatory so I can use it all year around. So now I need a sound system to play music and watch YouTube videos. I had a pair of JBL Control 25s and a Yamaha active subwoofer not being used as well as Spotify premium and desertcart HD to stream music - so just needed an amp. Nothing too big or powerful. So looked on desertcart and saw a variety of mini amps including this one. The reviews were good on this model and the clincher for me was that the headphone socket works at the same time as the speaker outputs - which sends a signal to my subwoofer. Sorted. Metal case, silver looks stylish, speaker outputs take banana plugs, aux in, Bluetooth and headphone out (which can connect to sub woofer as in my set up) Oh and a big on knob on top which doubles as on/off and volume. All set up and ready to go. Bluetooth found my phone (Samsung S7 Edge) first time and has not dropped out once. The sound is outstanding. Really. Very clean with plenty of power and detail. I can't believe this level of definition and easy power from such a small amp. In case you think I'm easily pleased, I have a full home studio with professional monitor speakers and in the past have had hi-fi set up's in the many thousands of pounds. I just wanted a nice little setup in my conservatory, which I have. But it's more than that. I normally use tracks I know well and of good quality to check new equipment. I started with Cold Water Music by Aim (a classic chill trip hop album, definately recommended). I would normally listen to one or two tracks and then onto other test tracks - but I sat and listened to the whole album. It was like rediscovering the album all over again. So much so, that I'm on to Hinterland by Aim, which is an amazing follow on to Cold Water. I'm just listening, nodding and smiling. Simple pleasures. This is what listening to music is all about. Enjoyment, discovering new in old, feeling excitement and being able to hear what the artist intended. This is what this little amp offers. Buy one. Connect to decent speakers with decent cable. Use Spotify premium or desertcart HD (Cold Water Music in 48kz). And enjoy a musical and Hi-Fi experience for a remarkably low price.

### ⭐⭐⭐⭐ Mine didnt work but has potential to be alright for cheap speakers
*by M***A on 19 January 2024*

I wouldn't use this for any speakers worth any substantial value, due to the fact that its missing an output filter, it has potential to damage speakers with high frequency square waves. Mine was unfortunately faulty and was refunded because the knob wouldn't press down to turn on. By opening it up and shorting the contacts, i was able to use it as a PCB. I did purchase one of amazon wearhouse though and it was packaged badly and likely got shipping damage. But for a 4ohm 100w x 2 amplifier, if it actually has the ability to hit that amount of power, its quite impressive. I must warn though, the tpa datasheet says it can only do 100watt mono at 2ohm, so im not sure what implementation they are doing to boost that to 100 watt at 4ohm. I cant lie, i reckon its only running 50 watt a channel at 4 ohm max, and they cheaped out on the circuitry too much to let it run the current demands of 2 ohm. Anyway, its cheap and aight tho. Unfortunate mine was faulty, i bought a better one with an output filter instead.
