“The CMA800R features an additional voltage-controlled current source and a current amplifier in front of a more traditional Class A output stage”
Cool so it looks like it’s not fully, but it honestly does sound more like one than the rest of their lineup (with the 800s at least). Still can’t find the output impedance though (since I’m now actually curious)
Typically you will find most current drive output impedance are in the hundreds, thousands, or even millions on some select amps. Lowest I’ve seen it go for a current drive amp is 40 ohms, so they are getting lower now, but if it’s really anything below that, it’s likely not
