Must be nice to not have to fight the huge supply chain demand from NDSP, Line 6 etc., for the SHARC supply.

Pretty certain that SHARC DSPs are easier/cheaper to source than Keystone's - and SHARCs are usually much easier to incorporate into a design, as they require less accompanying hardware to work.
@FractalAudio might be kind enough to shed some light on why
but what's pretty amazing IMHO is that they still managed to hit the $700 price target. Nice job.

Get the kettle on, I'm coming round...
Too late I’ve already eaten the included chocolate Santa.
Time to play badly through a brilliant device.
Initial impressions are just wow.

The actual latency of the AM4 is:I don't why I watched this but the comments are hilarious
someone is claiming the latency of a Plexi is -70, that you actually hear the sound before you hit the strings
Unbelievable
No blocks: 1.33 ms
Amp only: 2 ms
Amp + Cab: 2 ms
Drive + Amp + Cab: 2.67 ms
The cab processing adds no latency. Any extra measured latency is due to the IRs themselves. IR's are inherently band-limited and therefore have "latency" between the IR beginning and the peak in the response. A real speaker cab has "latency" if your method of measurement is looking for the peak in the response (which is technically an incorrect method).
We could reduce the latency by using minimum-phase resampling (the Axe-Fx offers this as an option). Many products are minimum-phase resampling by default. However, minimum-phase resampling causes phase distortion which I personally find more objectionable than an extra ms or so of latency.
Regardless, an average latency of 2 ms is extremely low.
