Nobsound Dual TPA3116 Digital Power Amplifier - High-Fidelity Stereo Amp With NE5532P Pre-Amp, Audiophile-Grade 2.0 Channel And 100W×2 Output (Black) Review

My application: home theater, Polk Audio "bookshelf" speakers rated for 20W RMS continous @ 8 ohms resistance, powered by 6A,19V laptop power supply, fed by audio output from a Behringer mini equalizer. I've been struggling for years to keep an old Yamaha 100W stereo amp working on this system, but finally got sick of jerking around with one side of it cutting out, and other symptoms of age. That amp is now headed for the "e-waste" pile, and good riddance.This "Class D" amp (high efficiency/low

I'm going to write one review that covers the Nobsound NS-10P, TPA3116 power amp, and the power cable for the power amp. I bought a Monoprice 16153 50W hybrid amp in Nov 2016 that lasted about a year and a half before having problems. Letting it sit unplugged seems to have fixed it (?) but then started again. Replacement tubes seemed to have fixed it that time, but when it had problems again about a year ago another set of new tubes did not fix it again. I will say that compared to this solid…

I got this because my old shop stereo (yes, really old.….dual cassette decks, 5 CD tray, AM/FM) bit the dust after an electrical storm.Since the speakers were still good & input comes from a remote Sirius receiver, all I needed was an amp & this got the job done well. Plenty of power for my use, but no equalizer. Sounds good even without the boost of an equalizer.Don't forget to also order a power supply as that's not included. I got the Nobsoundhttps://www.amazon.com/gp/product/B074J81XRB/ref=p…

If you have sensitive speakers that you plan to have near you (like computer desktop speakers), this is a great choice. Since it doesn't have tone controls, or a Bluetooth module, it reproduces what it receives perfectly and with zero noise. The choice of just adding an opamp is the cherry on top, which helps on impedance matching and prevents twitchy effects from adjusting a volume knob like other amps with the same chipset.As of note (and from experience), don't use a power supply with an…

Tested the outputs on a scope and see clipping at 10V pk with the factory 19V/4.7A supply. This is equivalent to about 6Watts RMS into 8 ohms. Check the TI data sheet for TPA3116D2 and they spec 100W only for 2 Ohm load with bridged output, with max 25V DC supply. Bottom line - if you use this with 8 ohm speakers, and factory 19V DC supply, dont expect to rock out, use 4 ohm speakers and 25V DC supply for reasonable volume that you would expect from any medium power stereo. Also - ordered…

I'm very happy with this system. It sounds as it should. Very powerful for my 4ohm 25 watt continuous Behringer 1C-BK studio monitors. Have it turned up maybe 15%, so it should theoretically last a very long time, which is what I want, after dealing with so many active studio monitors failing on me.There is a delay when you turn the volume, so be careful not to destroy your system or hearing with it. Slow and careful. I also have a volbox attenuator that lets me control the signal to the amp…

I've been an audio enthusiast for many decades now, and have listened to and evaluated all sorts of audio equipment, some of it pretty high end. This amplifier presents a bit of a paradox to me. It does some things very well, and almost amazingly well for the price, while other things kind of rule it out as a an amplifier that would satisfy an audiophile.First, a quick comment: This didn't come with a power supply, and it won't work without one. You have to provide your own 19VDC power supply…

I bought this as part of a setup for a sound system on my porch. I attached a bluetooth receiver to it, and have it powering two 45 watt outdoor speakers. I have the amplifier set at a little less than half gain, and I'm getting plenty of sound out of the speakers. With my iPhone at near full volume it's plenty loud enough for a decent party on my 1/3 acre property; and perfect for background noise at low volume. The amplifier works just as well at full gain, no distortion, just was too much…

This is a great little amp. I have it driving a pair of ELAC Uni-fi UB5's and the sound is perfect. My only gripe is the lack of a proper power supply. I had to go find one that worked properly, and be aware of the sparks if you have it on when you plug it in. Otherwise GREAT amp for the price.

This was a fantastic purchase. Wasn't quite sure what to expect but for the price and its size this was a great buy. I have it plugged into a pair of Boston Acoustics speakers (4" woofers) and running along with a tube -- yes, TUBE -- preamp. Sound source is an iMac with the midi control set at 24/96 and it sounds great! Don't expect this to sound like a McIntosh or a Krell electronic setup, but for the price and how I'm running the gear, it's perfect for my ears!

I bought this to power a pair of speakers for my backyard and am very happy with it. I initially bought a similar looking model that was priced at $37 which had terrible sound quality at medium to high volumes, so I returned it the next day and ordered this.This amp is a huge step up in quality. My two backyard speakers can be turned up loud enough to where I’d bet the whole neighborhood can hear the music with no drop in quality. Very happy with this so far. I’ll update in a few months if…

This looks to be a very well-built mini-amp. The tiny rubber/plastic feet keep it from slipping around on my entertainment center, and the speaker connections will accommodate bare wire or banana plugs, but since they're small and closely spaced, banana plugs are much easier for me to use. I also need to use a DAC to connect to my TV which has a coaxial audio output only.The reason I bought this amp was because I had read somewhere that amps with the TPA3116 chips have better sound quality than

Great little amp for the price. I paired it up with a Sonos Connect and a pair of old KLH Model 23 speakers than have been restored. Power supply is a 24v/1 amp unit I had lying around. Very nice, low price system that can be essentially left on all the time. I use Roon software to control music around the house and this setup is in the Master Bedroom for low level listening.The amp is very quiet with no signal noise regardless of the position of the volume knob (when music is not playing)…
