- This is Nobsound's new power amplifier in 2022. Based on our previous product, we enhance its output power and improve its functionality, while still keep its mini size and elegant design.
- Despite its mini size(can be hold with one hand), the output power is improved to 100W(50W*2) with the upgraded chip. You will be amazed by its output power compared to its size when you see it.
- Supporting AUX/USB/Bluetooth input. You can enjoy your music in different ways. The Bluetooth function is also upgraded to 5.0. Now it is more stable and faster.

That monoprice amp is primarily for multi room audio.
Why do you want an amp with no volume control? You already have a pre-amp or will be controlling the volume from the audio source? What will you be using it for? Which audio sources and which speakers to power?
Typical desktop amps under $100.
Nobsound Mini Amp with AUX/USB/Bluetooth Input, Kinter K2020A+, SMSL SA50, Dayton Audio DTA-2.1BT, Dayton Audio DTA-120BT, Micca OriGain $80 or with USB DAC $100.
Larger amps over $100.
Rebranded Dayton Franklin Audio IA150 150W Power Amplifier $130
Russsound and Audiosource Power Amps $130+
Budget Receiver:
Denon AVR-S530BT $140 refurbished 5.2 with sub out and adjustable crossover, HDCP 2.2 and HDMI 2.0B for 4K video switching.
Save more money or just get a pair of headphones. $30 is really into the "nothing worth wasting money on" area. If you just need "sound" get a pair of CyberAcoustics from Walmart or something.
If you want something that actually sounds good, you'll need to more than double your budget. Cheapest I can recommend;
This amp will hook straight to USB on your PC, has BT, all the connecting cables, and will put out decent sound, for $31
Clearance pair of decent 6-1/2" bookshelf speakers that come with speaker wire, for $25+ shipping. You seriously will not get a pair this good for this price anywhere else
With shipping, slightly double your budget, but worlds better than a crappy pair of cheap PC speakers.
It will be easier to add a sub to the MB42X. It is possible to add a sub to the PB42X, but you will only get bass from the left channel (which is usually fine). The PB42X setup will most likely be cheaper though.
If you wanted to do separates, I would get:
MB42X $80
FX502SPRO Amp $68
Franklin (rebadged Dayton SUB-1000) 10" Subwoofer $100
Speaker Wire
You could also get Dayton B652-AIR speakers for $50 to save a few dollars. They will be louder and have a bit more bass than the MB42X. MB42X sounds better overall though.
A cheaper amp is one of these little Nobsound units for $30. The FX502SPRO is leaps better and much more future proof, but if you're trying to stick to your budget, the nobsound isn't half bad.
To connect a sub to either of these setups, you'll use the High Level speaker wire connections on the back of the subwoofer. For the PB42X you would feed the wire that goes to the left speaker through the sub and then to the left speaker. For the MB42X you would run both left and right through the sub terminals.

Buy a sub when you have the cash - anything dayton audio
You clearly have no idea about how amps are built or what determines the output power. So maybe hold off on pronouncements about all amps.
There's always someone who'll shout about how they bought one and it worked for them. Woo hoo, a sample size of one. But the facts speak for themselves. See the Amazon comments about the amp you mentioned, they say exactly what I've been saying - quality control problems, fails, bugs, etc:

Which, again, is not to say that someone shouldn't buy them if that's the right tradeoff for them. If someone wants to save the money and can deal with a chance there will be some hassles or returns; and it may not last long - that's fine. I've been there, when I had time but not money.
It's just good to know what they are getting into, and maybe to buy from a vendor (Parts Express or Amazon) where there's some recourse if there are problems. And also, what they are really getting - eg the output power of that amp is likely closer to 10W per channel at 8ohms than 50W.
And BTW 10 watts is fine if someone is sitting not too far away or otherwise doesn't need the speakers to get too loud.

would something like this be enough or is the lepai better?
I'm assuming, based on your other responses (and because you haven't specified) that you're hooking this up to a computer exclusively, and that you have limited desk space (meaning that standard bookshelf speakers won't fit). Also, I'm going to assume that you don't have SPDIF or optical connections, since you haven't said that you do.
My suggestion, then, would be:
At their price and size, the Miccas are great speakers.
The Nobsound was reviewed by Zeos a while back, and he was pleasantly surprised. Note that you can attach the amp to your computer using USB, the 3.5mm jack, or bluetooth.
The speaker wire is there just to remind you to factor that into your cost. You may already have some laying around, or you can probably find some cheaper than that, or in shorter lengths.
Optional:
Just stumbled across your NOBsound Micro Amp review and really liked what I saw. Is there a reason this amp isn't recommended on here anywhere? I realize the original unit you linked to from that review isn't available anymore, but there is a different unit available now, for what seems to be $5 more than the old one, but it looks identical.
Unfortunately, it looks like shipping will cost quite a bit, so lesson learned. I'll probably upgrade to Atmos surround sound eventually, so I'm going to keep these.
My desktop setup sort of doubles as a home theater, so I may need more power for when I sit on the couch. Do you have any other recommendations? I was thinking about the Nobosound Mini BT, but the reviews are mixed.
