Aha, this is an argument for active pre-amps. Passive pre-amps presumably all have no gain.

So I guess that, given that my project is about exploring Class A with my speakers, that IF I buy a pre-amp, it too needs to be Class A.

And I suppose I find out whether there are any Class A DACs, because I think their analogue end must involve some gain.
