My Maximum equipment power level is 1557 and have run high level well spring, 3 crucible matches, and 3 vanguard ops with subclass matching the elemental burn. All three have dropped their pinnacle at 1557. Before it's asked I am not taking into account my seasonal artifact bonus levels. I am using DIM and destinyrecipes to see the max. power level, both state it is 1557 2/8ths.
