I second Purist Audio, maybe you are lucky to pick up an used pair of Venustas slightly above your budget. HiDiamond is well rounded and their D7 falls into your budget.
Both are excellent, no fatigue at all.
Re NordOst, I would try their current version to avoid the sharp edges they sometimes display. Heimdall(2) may indeed be the sweet spot for you.
AS you have DIYed your own speakers, I trust you use prime quality parts for the cross over, otherwise I would (re)start there.
