I am by no means a sound engineer, but the mid and low range frequencies are much richer on my passive Bang & Olufsen architectural speakers (which are powered by the Amp) when I stream through my Android TV versus other devices (laptop, tablet, phone, etc.) that aren’t directly connected to the Arc via eArc. I understand how many permutations are involved there. I have tried to control for as many of them as I can. What I am really wondering is if the Arc woofers produce frequencies from the passive speakers in certain configurations with the Amp and not in others that seem almost identical?
Thanks for any insights.
