I need a lesson on S/N ratio.
I'm not interested in the amp section of A10. (I only listen to it with IEM and on the go, so hiss and S/N do not have to be stellar.)
If I didn't understand wrong, what you'r saying, @ClieOS is that when I connect A10 to my E12 via LOD, if I chose low gain, then there would be less hiss?? (Yes, when I switch to low gain I do not hear the hiss) Does that mean that I'm better off with low gain and I get a better S/N ratio?
I want to get the best of A10 SQ wise. So far, A10 > LOD > E12 low gain seems to work OK.
Now, do I have a setup that is in the league of those hifi bricks as @castleofargh put it or not?
For that to happen, we have to assume that the SNR on the A10's line-out is good enough that, after E12's amplification (*which don't forget E12 has its own SNR as well), the final SNR will be better then A10's headphone-out. Usually when a DAP's line-out is high enough (which means the DAP is what we usually refer as a 'clean' source), that will be true. But given A10's line-out isn't actually that high, it can go both ways depends on the setup.
