These are exactly what I expected Fosi to develop based on the user input that was shared here. It's just a bit more expensive than I was hoping, but within ballpark and definitely at a price point that won't be a stopper for people who really want monoblocks. I wasn't expecting the shared power brick capability, that's a plus in my view, one less box.
The main stopper for me on this is that there is no matching solid state and multiple input preamplifier from Fosi to pair with it. Therefore, I'm going to sit on my hands and not be an early adopter of these, as the Fosi V3 and Aiyima A07/A07 MAX amps are still fulfilling my current small amp needs. By the time they get a good non-tube preamp built and offered, there will probably be the next generation version of these amps or a stereo one.
I think for people wanting more power, and XLR connections, but not wanting to pay $500+ for a Hypex Class D amp or a Schiit Vidar for $800, these are available at about 1/2 the cost. And that's enough of a difference that I am expecting them to sell pretty well, even apart from the FOMO buyers.
