I am coming to you as a person who has no knowledge, asking people who claim to have some, or even a lot of knowledge... whether A vs A\B has any impact on the DYNAMICs of the neve card, if it were wired to the output buffer of a compressor, or if it is static. Whether it would behave just the same run after the compressor (inline).
This, in a nutshell, is the issue you're having getting your question answered. The question as you've framed it, as someone who claims no knowledge, isn't making sense to those *with* knowledge - and believe me, you have had some serious electronic engineering heavyweights already respond to this thread. So let's try to unpack things a little.
The BA283 can't operate in Class A/B, so that part of your question is moot and we can leave that aside. It is a Class A output stage. I think you're then trying to ask whether the BA283 will affect the action of the compressor before it - no, I can't see that it would, particularly if there's a buffer between the sections.
I think you're also asking whether the BA283 stage will saturate in a level-dependent way, or independently of the output level of the compressor section. I'd expect it to be level-dependent. It may therefore smooth out some loud peaks slightly, depending on how hard it's driven.
If there's something else you're getting at, perhaps have a go at rephrasing it and we'll see what we can do. In particular, I don't understand your distinction between "wired to the output buffer of a compressor" and "run after the compressor (inline)", so any schematics you can point to in order to clarify that may help.
*Edit*: on rereading, I understand you're also asking whether there's any real point in having the BA283 in the same box as the compressor. Not a great deal, as far as I can see - you maybe avoid balancing and debalancing the signal if everything's in the same box, but that may not be particularly audible and is unlikely to change the action of the compressor or the tone of the BA283 (as long as all the impedances are handled properly). Convenience? Rack space?
