These placed Amazon 'coupon' posts kill me.

Also, 24v x 4A is less than 100W, so you won't even get half the advertised power output with the supplied adapter.

96W (24Vx4A=96W) vs 100W... I wouldn't call that a huge misstep. But we don't know anything about conversion efficiency, though it's surely a class D, so it should be fairly efficient. But that doesn't take away from the fact that it feels more like a placed ad than a sale.

Listing shows 100W x 2, so 200W total output.

Isnt it more like 35-40w x 2 assuming something like 80% efficiency? yeah not close

Class D is usually closer to 90% (though variable as it depends on the output impedance), but still, as energyx pointed out, I missed the "2x" and thought it was 100W total, so it's supposedly actually 100W per channel, aka 200W total, which is indeed quite far off and not likely to happen.

Yeah, oops. I missed the 2x. Definitely have serious doubts now (not that I was going to buy this anyway), but I really wouldn't recommend it even before that, this just confirms it. Thanks for catching that.

Not sure about the comments above, but I have this powering my 2 Yamaha outdoor speakers and it works great!

TPA3116 chip can do
50W x 2 into 4 ohms
30W x 2 into 8 ohms
So, 100W is maybe 2 ohm spec, which none of the speakers use. Don't trust these Chinese crappy brands. They lie about their specs.

Has this Amp been tested by "Big D" from Williston Audio? :-) Checkout his youtube channel to understand how he performs the tests, Enjoy!!

This is a decent deal. I use their Bluetooth receiver hooked up to a parasound amp powering a pair of Polk Signature bookshelf speakers and it sounds good with 24 bit at 48khz output via AmazonMusic HD.. $50 for a Bluetooth receiver with enough power to run a pair of small towers or a set of bookshelf speakers is pretty good.

I'm not sure if it's the same "UPGRADED" version but I bought a 1Mii bluetooth amp a few months ago to power some speakers in the kitchen. It works fine for the most part but the bluetooth has a major issue in that it automatically reconnects pretty much no matter what you do. I want to send music from my phone but the amp keeps auto-connecting to my phone every time I get within range, meaning I can't connect to other bluetooth devices on my phone like earbuds/headphones. More than once I ended up blasting to the kitchen, a podcast I was listening to. The only solution I came up with is to hook up this amp to a smart plug so that I can turn off the amp from my phone and keep it turned off until when I actually want to play music in kitchen. I really wish I had gotten a different bluetooth amp.

Never mind, it worked through the link.

These amps have poor SNR and leak a lot of random electrical noise into the signal. If you are sitting near field you will hear all kinds of pops and high pitched whining sounds from your tweeter which will be audible when no music is playing.
