Lets you focus on the speakers and the room which are really where the high end is accessible for reasonable money.
I use their high power Bluetooth amp with a pair of hard to drive Cambridge Soundworks speakers and it drives them with ease.
I personally like their tube preamps which allow you to try out different tubes to see if you like the effect. It's often subtle, but I find it preferable to DSP. I've used super expensive tube preamps and would still pick one of the Fosi with Bluetooth and a remote as the performance is very similar to something costing $500-1000. As most things audio, it comes down to preference and gear used.

Also, I didn't realize this lets you do opamp rolling!
It's the digital equivalent of tube rolling and has an audible effect on sound. I've got Burson and Sparkos opamps I switch out occasionally in my way too expensive Burson pre amp and it really does change the sound signature more than you'd imagine.

If you buy them separate pay close attention to the power supply, as it has a large influence on output.
At 8 ohms these push an honest 35wpc with the 32/5a supply or 90wpc with the 48/5a supply, so the power supply is very important. 4 ohms is 60 / 140 watts based on the power supply.
Bridged isn't linear, 4 ohms in one channel is about 200 watts with the big power supply.
That's within spitting distance of most midrange AVRs, and better than most all of them on the low end.
They're doing this type of product really well, and I hope they keep it up.
