yes I agree with your suggestion, which is in line with my first post.
@rajugsw does not agree.
And for your information, I run an integrated amplifier ( Soulution INT 330 )
for 2 channels music listening . I also used it ( home theater bypass )with my Acurus ACT4 20 channels ( 9.5.6 speakers layout )
home theater processor for video watching.
I think , I understand how it works.
