Just try to envision that there's more than a power inlet in there. Start thinking about the transformer. Next there are amplifiers against the side walls. Oh, there has to be a power supply somewhere.
And when some space is left, we need some input selection stuff and a bit of volume control (PCB) and that kind of thing.
This is at the best position I could think of, with the 100% clear notice (again !) that no secundary inputs (say other than from the D/A converter) will be treated as "the best ever" anyway. So when there is no BNC in order it is or XLR or RCA, and in case it is RCA it will be the rightmost ones.
I think it is optimal.
Of course not thinking in terms of a 42.5 x 42.5 case ...
Regards and thanks !
PS: My good old subject again : If you can incur for noise by means of the cable position at the back of the NOS1(a), you have another problem somewhere. Only when I lay out the lot the worst possible (like right over the transformer when testing something) I can *see* a bit of 50Hz creeping up towards -120dB (outside from what we always see). But hear something ? hahaha NEVER. By that time I'd need to let rise that noise or hum etc. with another 50-60dB. So go figure how one will be capable of that
. As said, when doing something else wrong (and not the slightest).
Btw, you can bet that I am super careless with the cabling and all the testing stuff I *always* have around, here. You see the pictures often pass by ...
(also loudspeakers did not degrade for sensitivity
