Nobsound NS-20G Mini Digital Power Amplifier Bluetooth Hifi Stereo Amp 100W+100W with power supply (Black)

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.

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 Amazon HD to stream music - so just needed an amp. Nothing too big or powerful. So looked on Amazon 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 Amazon HD (Cold Water Music in 48kz). And enjoy a musical and Hi-Fi experience for a remarkably low price.

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.

Just received and connected up this amp and honestly I’m blown away. I’ve connected it to my Dali Zensor bookshelf speakers, and have connected via Bluetooth on my iPhone 7 Plus. Pairing was instant and I’m streaming from Spotify, and the sound is unbelievable, this device obviously has a very good Bluetooth sound processor and creates a clean bright punchy sound, in fact I would say the low frequency is better than my Denon. I am amazed at the sound from something so small and light, it is quite amazing. It doesn’t have tons controls but this is fine, the sound is pure and clean, and obviously transmitted based upon the setting in the source. It also has the ability to drive an active sub woofer via the headphone socket, as well as headphones. The iPhone produces very good sound quality and my Spotify is set to high rate stream, with a balanced tone setting, so my review is on this basis. If you use an inferior sound source It will not do justice to this amp. I’ve a few different uses for this amp but just for reference with regards to this review my speaker specs are : Sensitivity (dB): 87 Impedance (ohms): 6 Power Rating (Watts): 100 Freq Response (Hz) 53 - 26,500 Speaker Enclosure Type Bass Reflex In short this is an excellent product for its size weight and price, I’m really impressed and will likely buy another at some point, if you’re looking for a Bluetooth sound solution in rooms just get one of these and a pair of bookshelf speakers. You can of course buy all-in-one Bluetooth speaker solutions now but you’ll spend around 2-3 times the money and it will take up more space. Using this product and two speakers also allows you to split up the speakers for good stereo sound which you can’t do with a stand alone Bluetooth speaker, maybe not a big factor but still worth considering!

I got around today to setting this up. Connected a single speaker as a test. I used the supplied cable to connect the device to my soundcard and, to my delight, music began to play from the speaker. Then, after 2 minutes, it stopped and has never resumed. I've connected the device to a different computer. I have replaced the supplied cable with one of my own. Nothing happens. The device's LEDs are all working … just no sound. I am sure there is a market for these devices. I am sure I am a member of that market. It's possible that I have been very unlucky but I am very disappointed.

Brilliant volume and sound quality/ output for the size and price you pay - using it to power some Vibe 4 Ohm 6x9” speakers at work next to a noisy press line, and can still easily hear music over the noise of the press - opted to use car speakers to take advantage of the amp doing full power output at 4 Ohm, whereas typical home audio/ HiFi speakers are 6-8Ohm and wouldn’t take full advantage of the power output of the amp etc. it does get warm to the touch, but that’s to be expected due to the size and the internals using the body of the amp as a heat sink. Overall, very impressed, and considering getting another NS-20G, daisychaining from one to the other (using the PHONE port) and running PA mid drivers from one amp, and using the second to run some PA compression tweeters for extra sensitivity from the speakers and more output/ volume!

good value and works. seems to be a bit of a fire hazard though, as there's a small spark when you plug the power cable into it... so i keep it switched off at the wall when not in active use. doubt it contains a fuse. only way to control EQ is by pressing the button which switches between preset modes... none of which seems to be particularly broad in lower register/bass. ofc, if you connect via Bluetooth you may be able to just use EQ from the device you are connecting from... but if using a device such as a record player, this amp is less good for use as a treble vs bass control

I have speakers pre-built into the ceilings of my home rated at 100W each. I wanted to stream music to them. This amplifier is remarkably small, runs cool and does it's job very, very well. It has a very low noise level (Inaudible) pumps out great sound without colouring the music. I'm very happy and impressed with this amplifier. I have bought several of them now and it has saved me a fortune in multi-room audio. Sonos has an offering at £600 per room and a fancy little app. I did a workaround. 1X Google Chromecast = £30 1X AGPtEK Ultra HD 4K x 2K HDMI to HDMI (SPDIF+3.5mm) Audio Extractor £23 1X Nobsound NS-20G Mini Digital Power Amplifier Bluetooth Hifi Stereo Amp 100W+100W £50 For just over £100, I can stream music from Spotify, Youtube and other castable music to each room in the house. I have X2 of these systems set up now and will add more to other rooms. It works really well and is very reliable. I never turn them off. I don't use the bluetooth, although I tested it and it worked well also. This is a bargain. Delighted with this product!
