Don’t know but I have the Fosi v3 stereo amp in my little desktop system. It is a top performer. I suspect it has output limits that may not cut it with some tougher speakers to drive but have not put it to the test yet.
The Fosi v3 amps are a steal in any case. No harm in trying a pair. If not quite up to snuff, you at least have a capable backup amp in case needed someday. Things break so always nice to have an effective spare around that cost relatively little and take up practically no space.
You might be pleasantly surprised and save a lot of money. You never know. Definitely a possibility for many.
