How did you got that?... well am human i listen with my ears and no by Numbers in sheets and lines...

i receive today the response i was looking for from the B&W team and this is what they said
" Good morning *******,
Thank you for your email regarding the Bowers & Wilkins MM-1.
If you decide to use an external DAC, you must use the Aux input of the MM-1. This will bypass the internal DAC of the speaker.
With kind regards."
Even tho it was a brief response, that was just what i was looking forward to hear...i didn't even had to wait that long to find the answer i was looking for. just by plugin in the external one, i knew their answer already...
i don't hear much the bass from the small 3 inch drivers, i use an external sub so i cant relate to that...
