Reddit reviews Nobsound 2 Channel Power Amplifier Mini Audio Amp Hi-Fi Stereo Class D Home Speaker 50W x 2 TPA3116 (no Power Supply)

I think that's a bad combination. It will technically work, but with its THUNDEROUS 4WPC max output, the amplifier is going to run out of power FAR too early for movie playback. If this were just for background music on a patio at a restaurant, it'd probably be fine. But drastically underpowering a pair of speakers is a good way to blow the tweeters as the distortion products climb.

I'd use one of these, with a old laptop power brick:

I have this amp, can be found for $25 on ebay if you're willing to wait, https://www.amazon.com/Nobsound-TPA3116-Channel-Digital-Amplifier/dp/B00WTOAC1M/

Has the TI TPA3116 chip, and is in a nice looking aluminum case. Needs a separate DC adaptor, but they're pretty common.

Completely new to this hifi thing and was going to get a closed box 2.1 system for around $150 now Im thinking I will start with

$90 Micca MB42X pair

$40 Nobsound Mini TPA3116

$11 Speaker Wire

Do I need anything else to make these work? Should I consider anything else (willing to go up to $200 if its significant) ? I plan to buy a sub later down the line when my budget allows it.

I have the Miccas along with this sub running off this amp. Glorious sound for just over $200 total.

I have the second generation Scarlett solo.

Ive got a pair of Sony speakers I took form an old cassette CD and radio. Cassette and CD motors don't work anymore but I think everything else works if that helps.

The amp is [this] (https://www.amazon.com/gp/aw/d/B00WTOAC1M/ref=ya_aw_od_pi?ie=UTF8&psc=1)

Your guide is awesome, but I have kind of a special use case that I need advice on. I want a 5.1 setup, that uses my PC as a reciever (my motherboard has outputs for a full 7.1 setup), and is good for both gaming at my desk and listening to music/watching movies across the room on my bed.

The issue with my PC as a reciever is that it doesn't output enough power for some speakers. Right now, my GF's parents gifted a Sony 5.1 setup, but the reciever sounded terrible in my opinion, which is why I want to use my PC. L/R output loud enough for now with these speakers, but center/sub and RL/RR are super quiet. I have a Lepai 2024 as a stop-gap to get use out of my center/sub, which works ok, except that the bass sounds muddy, which I've read (I don't know) is an issue with the cheap amp.

I want to upgrade all around. I'm not an audiophile, so I don't want to spend crazy amounts, but I notice if it sounds like trash. I was thinking Micca MB24X for L/R, mounted on the wall above my monitor, and matching center placed underneath my monitor, the Dayton 800 or 1000 for the sub, and the $70 Sound Appeal for rears. To power it all, I was going to use amps. Somewhere on Reddit, someone was recommending this $40 amp, that supposedly has much better bass the the current Lepai I have and is cheaper than the SMSL 36 that's currently at $51.99 on amazon. Am I being stupid? Should I just get a reciever? I just don't want to drop $200 right now, I could buy one piece at a time doing it this way, but it does seem like a waste.

I went with 4 of these speakers, wired in parallel, 2 for each channel. You could get by with smaller/less speakers depending on the space you are trying to fill with music.

Went with this amp and power supply.

https://www.amazon.com/gp/product/B01DLIYOYK/ref=oh_aui_detailpage_o07_s01?ie=UTF8&psc=1


And then this cable for the CCA to amp


https://www.amazon.com/gp/product/B002JTOLH8/ref=oh_aui_detailpage_o07_s01?ie=UTF8&psc=1



and then some speaker wire to connect it all.



The speakers blend nicely into the ceiling and the sound fills the open area of my kitchen/living/dining room area. And that tiny amp can push those speakers louder than you would want to listen.


That is only a single zone for now. I wanted a multi-zone receiver, but even the cheapest ones are relatively expensive. These small chip amps are pretty cheap and you could get by with an old laptop charger for a power supply. This allows you to build a zone at a time as budget permits. My next zone will be the back patio to enjoy in the spring.

I have the original one of these, gray. I have an old nook color tablet running pandora hooked up to it with a couple of pioneer bookshelf speakers and an old sony active sub. Not very loud but pretty good quality. Here's an 40usd 50+50W one based on the tpa3116: https://www.amazon.com/gp/product/B00WTOAC1M

Starting to jump down this rabbit hole of audiophilism (is that even a word?) Looking to replace my AIWA CX-NA202 from the 90s.

​

Was going to just settle for an edifier r1850db but with many hours of research it seems that a passive set up may be the way to go?

​

The first passive setup I was going to attempt to try was the -

Nobsound Mini TPA3116

https://www.amazon.com/gp/product/B00WTOAC1M/ref=ox_sc_saved_title_2?smid=ADPE7GPX91ORE&psc=1

Micca MB42X

https://www.amazon.com/gp/product/B00E7H8GG2/ref=ox_sc_saved_title_3?smid=AFKH6OU9WWNFS&psc=1

Which puts me under ~$150

​

But I have been hearing people just recommending an AVR, which I have landed on the Denon x1400 or x2400 which I may be able to pick up used for ~$200. Should I pair this with a Micca MB42X? Or are their other speakers that would work better with this?

​

Budget and currency - Under $300, USD
In which country are you located - USA
Where can you buy from - Amazon.com
What you want to use it for (music, movies, games, all of the above, etc) - All of the above, this will be a setup for my computer.
On a desk or in a room (or both) - On a desk in my room
How big of a space and how loud - Approximately a 12 feet x 12 feet room, not too loud and don't need much bass for now (still want the path to add a sub thou).

Thanks all in advance!

If you have / can find a 17-22V laptop power supply you could try this ($40, no power supply included):
https://www.amazon.com/Nobsound-TPA3116-Channel-Digital-Amplifier/dp/B00WTOAC1M/

It's a 5.5* 2.1mm connector, looks exactly like the one on my Dell laptop 19V power supply. (To get the full power from the amp, use something closer to the high end of the voltage. See the "Product Description" for specs on how the power supply voltage affects the amplifier power. People do use 12V, because there are lots of them around, but the watts per channel will be reduced.)

The power also depends on the amps - you'd need a 4-5 amp power supply. (Total watts = volts x amps, with some efficiency loss as it runs though the amp; that will be the constraint on the total output power in both channels, total. Eg, a power supply with 19 volts x 4 amps / 2 channels = 38 watts per channel at 100% efficiency, a little less in the real world.)

Don't know anything about it other than what's on the web, but AFAICT they use decent components. The TPA3116D2 chip is a good one.

The Amazon page above has some alternatives in the comparison section.

And buying through Amazon has some advantages, if you find it's not as advertised.

I purchased this little amp, it has worked fine and will work for these speakers. It's on the cheaper side and doesn't have any optical or usb. If you want to spend a bit more you can get this one that has more connection options. I only use mine as computer speakers so don't need anything more. There are many other little amps in between, I'm no expert on them, you can try /r/audiophile or /r/headphones for more info, also /r/zeos .

As others have said, for $30... you'd just be wasting your money. The Dayton / Edifier recommendations really are your best bet and the absolute cheapest you'd want to go.... new.

If you can live with headphones for now, make a habit of checking used markets for bookshelf speakers! Decent speakers often pop up for ridiculous prices (I've snagged a pair of budget bookshelves for under $10 in the past, which retailed for around $140). Pair the best $20 bookshelf speakers you can find with a $30 class-D amplifier and an old laptop power supply (free), and you've got a decent system for $50 (or less, if you find really cheap speakers).

What are would be some good amp recommendations?

You could get powered speakers that have both optical and bluetooth inputs - like these:

​

https://www.amazon.com/Edifier-R1280DB-Bluetooth-Bookshelf-Speakers/dp/B0719C132V/ref=sr_1_4?ie=UTF8&qid=1550988904&sr=8-4&keywords=powered+speakers

​

Your TV likely has optical out - even if it doesn't you can use analog out. If your computer can output via bluetooth, then both inputs would be digital. There's also powered speakers that accept a USB connection.

​

Problem with powered speakers is that it's hard to set up a sub. If you wanted to go with a sub as well, you could get this:

​

https://www.amazon.com/rolls-SX45-Tiny-Stereo-Crossover/dp/B00102VWJK

​

And run the low frequencies to the sub and rest to the mains.

​

If you want to run a separate amp, I have heard that the TPA311X series class D amplifier chips sound good. See: https://www.amazon.com/Nobsound-TPA3116-Channel-Digital-Amplifier/dp/B00WTOAC1M

​

Then run speaker level output to your sub, and from your sub back to your mains. You could use an RCA switcher to control inputs to the amp. Like:

​

(You won't need the video connections).

Recently I got an amplifier like this ($20 on AliExpress). Just look for "Breeze audio 50w amplifier"

https://www.amazon.com/Nobsound-TPA3116-Channel-Digital-Amplifier/dp/B00WTOAC1M/ref=sr_1_2?keywords=50w+amplifier+breeze+audio&qid=1569576048&s=gateway&sr=8-2

You can get them for a bit cheaper off of eBay or AliExpress. My impression so far from a couple weeks of usage is that sounds great for the price- it drives my vintage Kenwood speakers really well. It requires a separate power supply, but if you have an old laptop charger that outputs at least 20v it'll work fine

I recently purchased a Nobsounds TPA3116 but have no idea what power supply to use with it. None of the various adaptors around my house fit it. Does anyone have any specific suggestions (with links)? Amazon has a "customers also bought..." suggestion, but it's 24v6a, when I've read recommendations to use lower ampage.
