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.

I believe my old school rotel amp is rated somewhere around 100 WPC RMS at 4 ohms, I suspect the ratings for this are dynamic?

They have the 3E on closeout right now for $99

If you want a cheaper DAC I've used this Prozor one on a gaming setup and its nice, but not as good as the Modi. Its $14.

The cheap class D might not sound as good as an A/B for speakers. The new premium class D sounds very good with low distortion.

One powers rear surrounds in a 7.3.4 system. One powers Zone 2 on my covered porch. They work great for the use case.
I use it for a jump from 9.2 to 11.2 surround channels, I thought Audyssey calibration would make my height channels even but my Fosi class D has more bass and recessed highs
