The Knicks hit $103 million in 2004-05 and went over $120 million in 2005-06. I haven't been able to find more than that, and the 05-06 number contains the retired Allan Houston (but still officially on their payroll).
However, next year, when Kobe, Gasol, Nash, and Metta increase in salary and Dwight potentially signs an extension, the possibility is on the table.
