good sized room. keep the subs.
for good or ill, in this price range I've gotta submit were it me, I'd have a terribly hard time justifying buying either brand without having heard it myself as that is a fair to middlinn' stash of cash about to be in play.
on the DAs.... heard them in a smaller room to be sure with AR tubes and DCS front end.
IMO? mo' power was needed than the 150/160 AR monos supplied as the bottom end was noticeably loose. in demanding passeages.
otherwise, they sure make a memory and I'm not a huge Wilson supporter overall but have noted a penchant for their former sophia line..
the DA should work in your room but again, I'd really get out to hear them and tow along your go to powewr plants if possible.
sorry, I'm totally in the dark on the Rockports though i get the feeling they are a mite more forgiving than Wilsons up top. dunno.
very good luck..
