Nobsound[New Upgraded] 100W+100W Mini Bluetooth 5.0 Digital Amplifier HiFi Stereo Audio 2 Channel Power Amp Receiver with Bass and Treble Control for Home Speakers (NS-15G Plus)

Ups:Tiny! Easily fits on my desk along other geeky stuffSound quality is quite excellent (compared to Yamaha HTR-3067 and Pioneer VSX-D514)Good connections instead of those spring loaded onesVolume control is a bit finicky near the quiet endDowns:Loud-ish pop from speakers if you use a smart plug to handle power on/off instead of volume knobSupplied power brick is... Adequate. Don't expect 2x100W though, think 2x30W

I'm amazed that such a tiny amplifier can be so good. Using a pair of Kef Cresta II bookshelf speakers rated @100W this little amp certainly powers them well. Powerful punchy bass and a high treble. I don't use the tone controls but they do work fine. I prefer an original sound.There is no audio 'thump' that you get at switch on. The unit doesn't even get warm near full power. (I've only used at 3/4 volume/power so as not to introduce clipping.The power supply provided is rated at 19 Volts, 4.74 amps and this is adequate. If you want to squeeze the most out of this little gem then I think you can go up to a 24 Volt PSU. (MAX!)Things I would like to see: a headphone socket and maybe an auto shut off when no signal is received! Very minor points that does not deflect what a superb little amp this is.It seems very well built (I have not had a look inside) but on the outside is is solid aluminium with aluminium Volume and tone control knobs.... Very nice indeed.Well pleased with my purchase and it will be used well :)

I really wasn’t expecting very much from this item and went for the upgraded version based on other reviews. I’ve paired it with a set of ProAc Studio Reference speakers and I have to say I’m very impressed with this NS15G Pro. Okay it’s already on an upward track with the speakers but remember they are normally paired to a rather special amp so this unit had a big hill to climb sound wise. Has it managed it ! For sure. A tiny little thing that is performing and punching way above its weight, yes it’s a little light on bass but the treble is good as is the overall sound and one should never forget that quality of sound is always lost over BT but having said all of that I’m liking it. It was very quick to pair with my phone and TV along with my Alexa speaker, but not sure I need that. It’s well built and the knobs feel nice and smooth in operation with a good click to indicate you have reached the off position. Sound quality is good even at higher levels and it fills my 50 foot by 30 lounge with no issues at all. Better than a very expensive Bluetooth amp ?Probably not, but for the money and occasional use I’m happy with my purchase. I’m hoping it will give many years of service and at this very moment see no reason at all why it shouldn’t.

Excellent little gadget for reconnecting old hi fi separates to quality speakers when speaker connections have failed over the years. However more than that it allows those same speakers to be used for your phone, laptop, even a main pc by way of bluetooth. The only problem I have found is that bluetooth doesn't always connect as easily as I would like, however that is an innate problem with bluetooth connectivity and not necessarily the fault of this gadget. The wired connection is excellent and has breathed new life into an old CD/Digital radio as well as MiniDisc and even a portable WAV/Flac player.

Previously played sounds from PC thru a Denon Midi System using 100w studio quality speakers - connected this little unit up & the sound is superb, head & shoulders above the Denon, V slight delay connecting to bluetooth speakers sited in other rooms, apart from that I cannot praise it enough - as previously said - seriously impressed
