Treyhoss,
First of all, just keeping them powered on (there is no power switch, though) will help burn-in. So, you can expect the effect in a few weeks before 30 days.
And, the difference (improvement or not) should be instantly noticeable.
I believe (not experienced) that P3A would work well with your D/D, but P1A has future upgrade and that's what I expect so much.
Other choice would be Bel Canto and Birdland in a similar price range. Good luck
