I'm not suggesting headphones, I suggested connecting the speakers to the headphone output.Easy. Why suggesting me with large Kali and JBL? They have large hiss audible in a few meters. And why headphones in my own room? They harm ears.
I am exploiting zero-noise small monitor speakers within a few feet. Zero-noise, good sound and convenience are things PC folks can use of; what is wrong with that? Any regulations that PC DIYers are forbidden to make use of those speakers?
Also regarding the larger Genelec noise, some other people may also have questions. Larger ones have large noise because of much larger power gains in the amplifiers.
This hiss SPL at 10cm also suggests that larger model has larger noise within same series. https://docs.google.com/spreadsheets/d/1n62hGAdKptSSKC74_fIT_R7DxFJ60YR2_O9C8x-vYQI/edit#gid=0
What I'm saying that you are overanalyzing things and imagining possible problems by just endlessly reading stuff in internet. For example, do you know what the noise floor is in your listening room? I can barely hear the noise from the 8350 is I put my ear right next to the tweeter but hearing that from 1m away when there is air conditioning on, refrigerator is making noise or the computer is on? No way that is possible.
So, how about you order some JBL 308p speakers and see how you like it? Now you get some actual experience on the subject instead of keeping on analyzing stuff on internet.
What if you notice that they sound just great and the noise does not bother you at all? You just saved a lot of money not to mention time. If you can't stand the noise and the analog connection makes the sound unbearable you can send the speakers back and think about the next options.
