These are the specs from Texas Instruments website:
Total Output Power at 10%THD+N
315-W Stereo into 4 Ω in BTL Configuration
185-W Stereo into 8 Ω in BTL Configuration
600-W Mono into 2 Ω in PBTL Configuration
Total Output Power at 1%THD+N
260-W Stereo into 4 Ω in BTL Configuration
150-W Stereo into 8 Ω in BTL Configuration
480-W Mono into 2 Ω in PBTL Configuration
Note that you do have to upgrade the power supply to 48V if you want to get the 75w per channel, otherwise you'll be getting about 56w per channel out of the box with the included 32V PSU.
But 75W per channel at 8 Ω is still really good for an amp of this size and cost, it is similar to most low end receivers that cost $300 to $600 (Denon AVR-S760H for example)
With the included power supply (32V 5A) this baby puts out 77 Wpc @ 4 ohm and 48 Wpc @ 8 ohm. Thats pretty good for the price and size; signal to noise is not great though.
For the low-end, at 20 Hz, max power drops to 55W @ 4 ohm.

Check out Parts Express. They have a bunch of different amplifiers and plate amplifiers for fairly reasonable prices. I've used them a bunch and I'm sure others on here can back me up.

I paid $74.99 for this AIYIMA A07 Pro TPA3255 Stereo... https://www.amazon.com/dp/B0BN8H8...b_ap_
Not sure if I missed it, but does this have Bluetooth?

I don't think the line out on this version is a true sub-out. I had to return mine and bought a Arylic b50se, which had a real sub-out. With a07, it wouldn't control the volume of the sub as I higher the volume on the amp.

This thing is little beast if you want an all-in-one. Not as powerful as the A07 Pro, but if you dont want to add a dac and want all the other stuff, can't beat this. I run it for a desktop set-up and couldn't be happier
How much of an improvement is this?
You should also be able to use a relay like this one on any amp that can be turned on with power rather than a non-mechanical on/off button.

Fosi V3
https://www.amazon.com/Fosi-Audio...0CGCSM1
I have the Fosi V3 with a 48-watt power supply. I got everything for just under $100 new on eBay a few weeks ago. I'm using it to add 2 additional speakers to my 9 channel receiver. My Denon receiver is equpped with preouts for 11 total channels. I keep the volume maxed out on the Fosi, have my receiver plugged into the master and the fosi plugged into the slave socket on a smart power strip so they power on and off simultaneously, and I calibrated everything with Audussey XT 32. I'm happy with it. I'm sure this little amp would work very similarly to the Fosi V3.
The Fosi ZA3 has a trigger, but it would be cheaper to use a smart power strip.

Knowing that, I love these things. They provide the ability to drive two quality bookshelf speakers at a fraction of the price of a traditional receiver. And a quality 2.1 (which this is just 2.0) setup is better than a budget "7.2 soundbar". I'm sure I'll get debated on that, but the fact remains that most media isn't 7.2. So most of the time, you're just funneling 2.0 or 5.1 audio into extra speakers for brag rights.
