Review: Works well and durable - Charges the battery on my ebike perfectly. No complaints so far...it's been over a year.
Review: good modular setup - 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 state power amp, the Monoprice was MUCH louder. At half volume the Monoprice was louder than this TPA3116 is at full volume. That difference made me rethink my setup somewhat, so if you are used to a similar style hybrid amp the difference is real. I have only used the stock (JJ) 6J1 tubes with the preamp so far. I set all the controls to 50% on the pre, and noticed there is some distortion that was fixed by backing off the volume knob. Something else to know either if you are going for a slightly distorted sound (spoken words are 'buzzy') or want more clean headroom. I think probably swapping the tubes will address that but for now it's just an educated guess. The 'fullness' that you want from a tube amp is less full in this NS-10P than it was in the monoprice amp, but that one also had multiple tube stages and different tubes, and I used better tubes than the stock ones shipped for most of the time it was working. The price difference though is worth it for a modular setup, that is both smaller and lighter, in case I end up with similar quality issues I can replace only the parts that go bad. There are a few different Nobsound products on desertcart and some of them address the issue of sparks when you plug in the power cable, claiming to have fixed the issue in newer versions. Sparks did fly connecting the provided power cable into the NS-10P. I did verify the power switch was set to off. I purposely connected the power first then the unit to see if I got one that would spark, you can totally circumvent the issue by connecting the cord to power last. No sparks when connecting the power amp. Still worth noting. The power cable for the power amp is completely unremarkable, it just works. Overall the sound is very good, this set up takes music from a PC and outputs to a distribution box so I can have speakers at either workbench across the span of my house's full basement. Not set up for massive volume but I want to be able to hear while tools such as a drill are being used. I wear hearing protection when using bigger tools anyway. I have these situated where the preamp is on top of a similar sized Fosi subwoofer amp (for a different setup) and then that sits on top of the power amp. These make a lot less heat even stacked up like that and sat next to a cable box than the Monoprice amp did. If I could change any of it, I would suggest they know these items are going to be used together, either use 3.5mm or RCA not require adapters to use the pre & power amps together. And/or the possible addition of optical (perfect size for a mini toslink and they do make jacks where it can be built into a 3.5mm) from the source. Pick front or back for the power switch (preferring front obviously) and common colour scheme for the knobs & lights. The blue lights do look cool on the preamp I will admit. I do not like that the volume on the pre is 'notched', while the treb & bass it makes sense you want to set those and leave it, you may want to adjust the volume occasionally on the pre. The power amp knob has no line to signify where in its volume range it is set; in my case it didn't matter because it's maxed out. Finally, I would have wanted a sub pre out also from the power amp, (understand now this does not have the power for a passive sub) but that's only a small detail and my speakers have enough bass it's not a necessity.
