The highest official round with non- daily challenge stuff is round 513 by marche on 3 times around, hard. It was not NAPS though, He used big bloon sabotage, bigger beacons, and tack awesomizer. He also used the tier 3 sniper specialty building.

In this video he showed round 510, but he went to round 513 until he messed up with his abilities and died.

check out this video, or try going to BTD5 leaderboard -> hard 3 times around.
