B&W 803D3

How would you rate the difference between 220 Pro and 440 Pro with the 802 D3?

I'm using 802D3 since 2016. I've tried 220-Pro, 440-Pro & 1000-Pro bi-wired. I also ran [2 x 440-Pro] bi-amped. For my current 32 Sq M room, I'm delighted with 440-Pro. 

220-Pro is under powered at least for my room size and won't bring forth the potential of the 802D3 in terms of soundstage dimensions, overall scale, strong dynamic shifts and an overall ease with smoothness that 440-Pro easily provides. 

I was bi-amping with 2 x 440-Pro but reverted to a single 440-Pro now upon adding a pair of REL G1-MKII subs. What the subs have brought forth cannot be matched by either bi-amping or moving UP to a 1000-Pro bi-wired.
