Hi,
i try to understand what is advantage of having VCA compressor in class a, especially sidechain electronics. It is about Focusrite Red 3, some of their statements:
The Focusrite Red 3 is a Class A VCA-based dual mono/stereo compressor/limiter.
The side-chain electronics are class A, ensuring superb transient response.

As i understand it, signal after sidechain VCA is rectified into dc, timed and then returned to main VCA. Of course there is more to it, don't have scehmatics to see how it is done, so can't assume it is similar to SSL 4k or THAT papers.
How can class a electronics in sidechain control do any good if it is dc and not audio ac signal? I mean dc is dc in this case, can't see any advantage in using class a op-amps if this is truth in Red 3, only complications and possible problems with reliability in the long run. I won't start on other class a claims, it just makes no sense to me knowing newer Focusrite a bit.
